-# RocksDB Code Generation and Review Guidance
-
-This document provides guidance for generating and reviewing code in the RocksDB project, derived from analysis of code review feedback across hundreds of complex merged Pull Requests. Use this as a reference when writing code with AI assistants or conducting code reviews.
-
---
-
-## General Best Practices
-
-### Code Quality and Maintainability
-
-**Clarity and Readability:** Write clear, self-documenting code. Use meaningful variable names, add comments for complex logic, and structure code to minimize cognitive load. Avoid clever tricks that sacrifice readability for marginal performance gains unless absolutely necessary.
-
-**Consistent Style:** Follow existing code style conventions. RocksDB uses `.clang-format` for formatting, specific naming conventions, and structural patterns. Deviations from these patterns are frequently flagged in reviews.
-
-**Error Handling:** Ensure robust error handling throughout the codebase. Use RocksDB's `Status` type consistently, propagate errors appropriately, and avoid silently ignoring failures. Reviewers pay close attention to edge cases and failure modes.
-
-### Testing Philosophy
-
-**Comprehensive Coverage:** Every change should include appropriate test coverage. This includes unit tests for isolated functionality, integration tests for component interactions, and stress tests for concurrency and performance validation. Reviewers will ask for additional tests if coverage is insufficient.
-
-**Edge Cases and Failure Modes:** Tests should explicitly cover edge cases, boundary conditions, and potential failure scenarios. This is especially important for changes affecting core database operations, compaction, or recovery logic.
-
-**Platform-Specific Testing:** RocksDB supports multiple platforms (Linux, Windows, macOS) and compilers (GCC, Clang, MSVC). Changes should be tested across relevant platforms, particularly when touching platform-specific code or using compiler-specific features.
-
-### Performance Considerations
-
-**⚠️ PERFORMANCE IS CRITICAL:** RocksDB is a high-performance storage engine where every CPU cycle and memory access matters. When writing code, always evaluate from a performance perspective. This is not optional—performance-aware coding is a fundamental requirement for all contributions.
-
-**Benchmarking and Profiling:** Performance claims should be backed by empirical evidence. Use RocksDB's benchmarking tools (e.g., `db_bench`) to validate improvements. Reviewers will request benchmark results for changes that could impact performance.
-
-**Memory Allocation:** Minimize dynamic memory allocations, especially in hot paths. Prefer stack allocation over heap allocation. Reuse buffers when possible. Consider using arena allocators or memory pools for frequent small allocations. Every `new`, `malloc`, or container resize has a cost.
-
-**Memory Copy:** Avoid unnecessary memory copies. Use move semantics, `std::string_view`, `Slice`, and pass-by-reference where appropriate. Be aware of implicit copies in STL containers and function returns. Prefer in-place operations over copy-and-modify patterns.
-
-**CPU Cache Efficiency:** Design data structures and access patterns to be cache-friendly. Keep frequently accessed data together (data locality). Prefer sequential memory access over random access. Be mindful of cache line sizes (typically 64 bytes) and avoid false sharing in concurrent code. Consider struct packing and field ordering to improve cache utilization.
-
-**Loop Optimization:** Look for opportunities to collapse nested loops, reduce loop overhead, and minimize branch mispredictions. Hoist invariant computations out of loops. Consider loop unrolling for tight inner loops. Batch operations when possible to amortize per-operation overhead.
-
-**SIMD and Vectorization:** Leverage SIMD instructions (SSE, AVX) for data-parallel operations when appropriate. Structure data to enable auto-vectorization by the compiler. Consider explicit SIMD intrinsics for critical hot paths like checksum computation, encoding/decoding, and bulk data processing.
-
-**Branch Prediction:** Minimize unpredictable branches in hot paths. Use `LIKELY`/`UNLIKELY` macros to hint branch prediction, e.g. for error cases and other rare or otherwise costly cases, but NOT for predicting popular configurations. Consider branchless alternatives for simple conditionals. Order switch cases and if-else chains by frequency.
-
-**Memory and Resource Management:** Be mindful of memory allocations, especially in hot paths. Use RAII patterns, smart pointers, and RocksDB's memory management utilities appropriately.
-
-**Hot Path Analysis:** When deciding how aggressively to optimize code, consider whether it's on a hot path:
- **Hot path** (executed thousands+ times, e.g., data access, iteration, compaction loops): Performance is paramount. Apply all optimization techniques—loop collapsing, SIMD, cache optimization, pre-allocation, etc. The cost of each operation is multiplied by execution frequency.
- **Cold path** (executed rarely, e.g., DB open, configuration parsing, error handling): Maintainability and clarity are more important. Prefer readable code over micro-optimizations. Complex optimizations here add maintenance burden with negligible performance benefit.
- **Warm path** (moderate frequency): Balance both concerns. Use profiling data to guide optimization decisions.
-
-**Avoid Premature Optimization:** While performance is critical, focus on correctness first, then optimize based on profiling data. However, be performance-aware from the start—choosing the right algorithm and data structure upfront is not premature optimization. Use the hot path analysis above to decide how much optimization effort is warranted.
-
-### API Design and Compatibility
-
-**Backwards Compatibility:** RocksDB maintains strong backwards compatibility guarantees. Breaking changes are rare and require extensive justification. When deprecating features, follow the project's deprecation policy (typically spanning multiple releases).
-
-**API Consistency:** New APIs should be consistent with existing patterns. Use similar naming conventions, parameter ordering, and return types. Reviewers will suggest changes to improve consistency with the broader codebase.
-
-**Documentation:** Public APIs must be thoroughly documented. Include usage examples, parameter descriptions, and notes on thread safety, performance characteristics, and compatibility considerations.
-
---
-
-## Component-Specific Guidance
-
-### Database Core (`db`)
-
-The database core handles write-ahead logging (WAL), memtables, compaction, and recovery. This component receives the most scrutiny in code reviews.
-
-**Concurrency and Thread Safety:** Database operations are highly concurrent. Reviewers carefully examine locking strategies, atomic operations, and memory ordering. Document synchronization assumptions clearly. Use appropriate memory ordering semantics (`acquire`/`release` vs. `seq_cst`).
-
-**Compaction Logic:** Changes to compaction are complex and high-risk. Ensure that compaction logic respects configured parameters, handles edge cases (empty databases, single-file compactions), and maintains correctness under concurrent operations.
-
-**Error Propagation:** Database operations can fail in many ways (I/O errors, corruption, resource exhaustion). Ensure that errors are properly propagated, logged, and handled. Avoid assertions in production code paths.
-
-**Testing:** Database core changes require extensive testing, including unit tests, integration tests, and stress tests. Test with various configurations, compaction styles, and concurrent workloads.
-
-### Public Headers (`include`)
-
-Public headers define RocksDB's API surface. Changes here have the highest compatibility impact.
-
-**API Design:** New APIs should be intuitive, consistent with existing patterns, and well-documented. Consider how the API will be used in practice and avoid adding unnecessary complexity.
-
-**Backwards Compatibility:** Breaking changes to public APIs require extensive justification and a deprecation plan. Maintain ABI compatibility for bug fixes and patch releases.
-
-**Documentation:** Every public API must be thoroughly documented with usage examples, parameter descriptions, and notes on thread safety and performance characteristics.
-
-**Deprecation:** When deprecating APIs, follow the project's policy. Mark deprecated APIs clearly, provide migration guidance, and maintain support for at least one major release.
-
-### Internal Utilities (`util`)
-
-Internal utilities provide common functionality used throughout the codebase.
-
-**Code Reuse:** Utilities should be general-purpose and reusable. Avoid duplicating functionality that already exists elsewhere in the codebase.
-
-**Error Handling:** Utility functions should handle errors robustly and propagate them appropriately. Consider edge cases like overflow, underflow, and invalid inputs.
-
-**Testing:** Utility functions should have comprehensive test coverage, including edge cases and failure modes. Consider adding death tests for assertions.
-
-**Performance:** Utilities are often used in hot paths. Ensure that implementations are efficient and avoid unnecessary allocations or copies.
-
-### Table Management (`table`)
-
-Table management handles SST file format, block-based tables, and table readers/writers.
-
-**Block Format and Checksums:** Changes to block format require extreme care. Ensure that checksums are computed and verified correctly. Test with various compression algorithms and block sizes.
-
-**Iterator Correctness:** Table iterators are used throughout the codebase. Ensure that iterator semantics (Seek, Next, Prev) are correct, especially at boundaries and with deletions.
-
-**Caching and Prefetching:** Table readers interact with the block cache and prefetching logic. Ensure that cache keys are unique and that prefetching respects configured limits.
-
-**Performance:** Table operations are performance-critical. Benchmark changes that could impact read or write performance.
-
-### Utilities (`utilities`)
-
-Utilities include optional features like transactions, backup engine, and checkpoint.
-
-**Feature Isolation:** Utilities should be self-contained and not introduce unnecessary dependencies on core database internals.
-
-**Deprecation and Cleanup:** Legacy features are being phased out. When removing deprecated code, ensure that migration paths are documented and that users have sufficient warning.
-
-**Cross-Platform Compatibility:** Utilities often interact with OS-specific APIs. Ensure that code works on all supported platforms.
-
-### Options and Configuration (`options`)
-
-Options define RocksDB's configuration system.
-
-**Type Safety:** Use appropriate types for options (e.g., `uint32_t` for flags, scoped enums for enumerated values).
-
-**Deprecation Policy:** When deprecating options, follow the project's policy. Document the deprecation, provide migration guidance, and maintain support for at least one major release.
-
-**Dynamic Configuration:** Some options can be changed dynamically. Ensure that dynamic changes are thread-safe and take effect correctly.
-
-**Validation:** Validate option values and provide clear error messages for invalid configurations.
-
-### Cache (`cache`)
-
-Cache management is critical for RocksDB's performance.
-
-**Concurrency:** Cache operations are highly concurrent. Ensure that implementations are thread-safe and use appropriate synchronization primitives.
-
-**Performance:** Cache operations are in the hot path. Optimize for low latency and high throughput. Benchmark changes carefully.
-
-**Memory Management:** Cache implementations must manage memory carefully to avoid leaks and excessive allocations.
-
-**Eviction Policies:** Changes to eviction policies should be well-tested and benchmarked to ensure they improve overall performance.
-

-
-## Code Review Checklist
-
-When reviewing RocksDB code (or preparing code for review), use this checklist:
-
-### Contract Boundaries
- [ ] Is each behavior owned by the right layer? High-level policy (for example,
-  "compaction wants this I/O mode") should live at the caller/policy layer, while
-  lower layers should expose generic mechanisms (for example, "open a fresh
-  reader", "skip shared cache insertion", or "use these FileOptions").
- [ ] Do comments and names describe local contracts rather than leaking a
-  specific caller's rationale into reusable APIs? Generic code should not need to
-  know about one current use case unless the API itself is intentionally
-  use-case-specific.
- [ ] Does each flag or parameter control one coherent behavior? If one boolean
-  starts implying ownership, cache policy, I/O mode, prefetching, and caller
-  identity, split it into explicit flags or an options struct.
- [ ] Could a future caller use this lower-level API without accidentally
-  inheriting assumptions from compaction, backup, user reads, or a particular
-  table format? If not, tighten the contract with assertions, clearer names, or
-  a narrower API.
- [ ] Are implementation details not being used as policy signals? Prefer an
-  explicit contract over inferring behavior from incidental fields such as file
-  options, cache handles, or current table-reader state.
-
-### Correctness
- [ ] Does the change preserve database semantics (e.g., snapshot isolation, key ordering)?
- [ ] Are all error cases handled appropriately?
- [ ] Is the change thread-safe? Are synchronization primitives used correctly?
- [ ] Are there any potential data races or deadlocks?
-
-### Testing
- [ ] Does the change include appropriate test coverage?
- [ ] Are edge cases and failure modes tested?
- [ ] Have the tests been run on all supported platforms?
- [ ] Are stress tests passing?
-
-### Performance
- [ ] Are there benchmark results for performance-sensitive changes?
- [ ] Does the change avoid unnecessary allocations or copies?
- [ ] Are hot paths optimized appropriately?
-
-### API and Compatibility
- [ ] Is the change backwards compatible?
- [ ] Are new APIs consistent with existing patterns?
- [ ] Is the public API documented?
- [ ] Are deprecated features handled according to policy?
-
-### Code Quality
- [ ] Does the code follow RocksDB's style conventions?
- [ ] Is the code clear and maintainable?
- [ ] Are comments and documentation sufficient?
- [ ] Are there any code smells or anti-patterns?

-## Common Review Feedback Patterns
-
-The following patterns emerged as frequent sources of review feedback:
-
-1. **Test Coverage:** Reviewers frequently request additional tests for edge cases, platform-specific behavior, and failure modes. Complex changes require comprehensive test coverage including unit tests, integration tests, and stress tests.
-
-2. **Error Handling:** Ensure proper error propagation using RocksDB's `Status` type. Avoid silent failures and provide clear error messages that include context about what failed and why.
-
-3. **API Design:** New APIs should be consistent with existing patterns. Use descriptive names that follow established conventions. Avoid breaking changes without strong justification and a clear deprecation plan.
-
-4. **Documentation:** Public APIs must be documented with usage examples and notes on thread safety, performance characteristics, and compatibility considerations. Complex internal logic should also be well-commented.
-
-5. **Performance:** Performance-sensitive changes require benchmark results to validate improvements. Use `db_bench` and other profiling tools to measure impact. Avoid premature optimization that adds complexity without measurable benefit.
-
-6. **Concurrency:** Thread safety is critical in RocksDB. Document synchronization assumptions clearly. Use appropriate memory ordering semantics. Consider potential race conditions and deadlocks.
-
-7. **Code Style:** Follow existing conventions for naming, formatting, and structure. Use `.clang-format` for consistent formatting. Prefer scoped enums (`enum class`) over unscoped enums.
-
-8. **Backwards Compatibility:** RocksDB maintains strong compatibility guarantees. Breaking changes require extensive justification. When deprecating features, provide migration guidance and maintain support across multiple releases.
-
-9. **Refactoring:** Reviewers appreciate refactoring that improves code readability and maintainability. Look for opportunities to deduplicate code and simplify complex logic.
-
-10. **Platform Compatibility:** Ensure changes work correctly on all supported platforms (Linux, Windows, macOS) and with all supported compilers (GCC, Clang, MSVC).
-
-11. **Contract Boundary Leaks:** When a change plumbs a new option or use-case
-specific behavior through multiple subsystems, review the call chain for
-contract leaks. Caller-specific rationale belongs at the call site or public API
-documentation; reusable layers should expose precise, layer-local capabilities.
-Watch especially for comments mentioning one caller in generic code, booleans
-that silently bundle several behaviors, and downstream code inferring policy
-from an implementation detail instead of an explicit option.

-## Important tips
-
-### Build system
-* There are 3 build system. Make for git clones, BUCK (meta internal) for hg
-  clones, and CMake for some special cases.
-* When a new .cc file is added, update Makefile, CMakeLists.txt, src.mk, BUCK.
-* Don't manually edit BUCK file, after updating src.mk, run
-    /usr/local/bin/python3 buckifier/buckify_rocksdb.py to update it
-* For -j in make command, use the number of CPU cores to decide it.
-
-### Avoiding mixed build modes with Make (use `AUTO_CLEAN=1`)
-
-Object files are written to the same paths regardless of build flags, so
-reusing objects from a prior build with different flags causes confusing
-linker errors, etc. This problem is essentially avoidable by ALWAYS using
-`AUTO_CLEAN=1 make -j<n> <something>` for manual make invocations. This
-will automatically clean object files if the build parameters/flavor have
-changed. The `build_tools/rockstest.sh` / `rocksptest.sh` helpers described
-below set `AUTO_CLEAN=1` for you.
-
-### Source checks
-* Run `make check-sources` before committing. This catches non-ASCII
-    characters in source files and other source-level issues that CI will
-    reject. In particular, **do not use Unicode characters** (em dashes,
-    smart quotes, etc.) in comments or strings -- use ASCII equivalents
-    (`--` instead of em dash, `'` instead of smart quote, etc.).
-
-### License headers
-* Every new source file needs a license header. For a file that does **not**
-    carry an outside/third-party copyright, use the standard Meta dual-licensed
-    header (the dual-license designation is required -- a bare
-    "All Rights Reserved" copyright is not an acceptable open-source header):
-    ```
-    //  Copyright (c) Meta Platforms, Inc. and affiliates.
-    //  This source code is licensed under both the GPLv2 (found in the
-    //  COPYING file in the root directory) and Apache 2.0 License
-    //  (found in the LICENSE.Apache file in the root directory).
-    ```
-    Use a `#` comment prefix instead of `//` for shell, Python, and Makefile
-    fragments.
-* Files derived from an external source (e.g. LevelDB) keep their original
-    upstream copyright line in addition to the header above.
-
-### RTTI and dynamic_cast
-* Production code and `db_stress` must build in **release mode
-    (`-fno-rtti`)**. Do not use `dynamic_cast` anywhere except unit tests.
-    Use `static_cast_with_check` from `util/cast_util.h` (validates with
-    `dynamic_cast` in debug builds, plain `static_cast` in release).
-* Unit tests (`*_test.cc`) are built in debug mode with RTTI enabled.
-
-### Cross-platform / portability
-Local `make` only exercises Linux with GCC/Clang, but CI
-(`.github/workflows/pr-jobs.yml` and `nightly.yml`) gates on a much wider
-matrix, so portability breaks are invisible locally until CI fails. Code must
-build (and where noted, run tests) across:
-
-| Axis | Must support |
-|------|--------------|
-| OS | Linux (x86_64 + ARM), macOS, Windows |
-| Compiler | GCC, Clang (libstdc++ **and** libc++), AppleClang, **MSVC (VS2022)**, MinGW (Linux cross-compile, build-only, no gflags) |
-| Build system | Make, CMake, and BUCK (internal) -- keep all in sync (see "Build system" above) |
-| Config | release (`-fno-rtti`), `ASSERT_STATUS_CHECKED`, ASAN/UBSAN/TSAN, folly, unity build, JNI/Java |
-
-Treat these as constraints to satisfy and infer the specifics from them before
-adding any system header, libc call, or compiler-specific construct. The most
-common trap: anything that compiles under GCC/Clang on Linux but not under
-**MSVC/MinGW** -- e.g. unguarded POSIX-only headers/functions (`<unistd.h>`,
-`<sys/*.h>`, `getpid`, `_exit`, ...) or GCC/Clang extensions
-(`__attribute__`, `__builtin_*`, VLAs, `alloca`). Prefer the `port::`/`Env`
-abstractions; otherwise guard with `#ifdef OS_WIN` (POSIX `<unistd.h>` ->
-Windows `<process.h>`). Because libc++ is also tested, include what you use
-rather than relying on libstdc++ transitive includes.
-
-### Unit Test
-* After all of the unit tests are added, review them and try to extract common
-    reusable utility functions to reduce code duplication due to copy past between
-    unit tests. This should be done every time unit test is updated.
-* Don't use sleep to wait for certain events to happen. This will cause test to
-    be flaky. Instead, use sync point to synchronize thread progress.
-* Cap unit test execution with 60 seconds timeout.
-* To build and run unit tests locally, prefer these helper scripts:
-    * `build_tools/rocksptest.sh <test_binary> [more_binaries...] [args...]`
-        builds the binary(ies) with parallel make and `AUTO_CLEAN=1` and runs
-        them under gtest-parallel, sharding the test cases across CPUs. Prefer
-        this whenever running more than a couple of test cases, e.g.
-        `build_tools/rocksptest.sh table_test` or
-        `build_tools/rocksptest.sh db_test env_test --gtest_filter=*Foo*`.
-    * `build_tools/rockstest.sh <test_binary> [args...]` builds with parallel
-        make and `AUTO_CLEAN=1` and runs the binary directly (serially).
-        Use it only for a very small number of test cases, e.g.
-        `build_tools/rockstest.sh db_test --gtest_filter=*MixedSlowdown*`.
-* After writing a test, stress-test for flakiness (AUTO_CLEAN handles the
-    rebuild needed by the `COERCE_CONTEXT_SWITCH=1` flag change):
-    ```bash
-    COERCE_CONTEXT_SWITCH=1 build_tools/rockstest.sh {test_binary} -r100 \
-        --gtest_filter="*YourTestName*"
-    ```
-* For CI-style flaky tests that do not reproduce with `gtest_parallel.py`,
-    `--gtest_repeat`, or normal coerce-mode runs, inspect
-    `tools/gtest_parallel_repro.py --help`.
-
-### Unit test dedup guidelines
-* Extract helper functions for repeated patterns such as object
-    construction, round-trip (encode → decode → verify), and common
-    assertion sequences.
-* Use table-driven tests (struct array + loop) when multiple test cases
-    share the same logic but differ only in input/expected data.
-* Prefer randomized tests over exhaustive parameter permutations. Use
-    `Random` from `util/random.h` (not `std::mt19937`). Use a time-based
-    seed with `SCOPED_TRACE("seed=" + std::to_string(seed))` so failures
-    are reproducible.
-* Keep deterministic edge-case tests separate from randomized tests
-    (error paths, boundary conditions, format verification).
-* Methods only used in tests should be private with `friend class` +
-    `TEST_F` fixture wrappers. In wrappers, always fully qualify the
-    target method to avoid infinite recursion.

-### Adding new public API
-    Refer to claude_md/add_public_api.md
-
-### Adding new option
-    Refer to claude_md/add_option.md
-
-### Removing deprecated option
-    Refer to claude_md/remove_option.md
-
-### Metrics
-* When adding a new feature, evaluate whether there is opportunity to add
-    metrics. Try to avoid causing performance regression on hot path when adding
-    metrics.
-
-### Stress test
-* When adding a new feature, make sure stress test covers the new option.
-
-### Component docs
-* For component-level design notes and implementation walkthroughs, start with
-    `docs/components/index.md`.
-* Documentation under `docs/components/` is organized by subsystem in
-    `docs/components/<area>/`.
-* Each subsystem directory should have an `index.md` entry point plus focused
-    chapter files for deeper topics.
-
-### DB bench update
-* When adding a performance related feature, support it in db_bench
-
-### Adding release note
-* Release note should be kept short at high level for external user consumption.
-
-### Blog posts (docs/_posts)
-* Blog post authors must be defined in `docs/_data/authors.yml` to be displayed
-
-### Final verification of the change
-* Execute `AUTO_CLEAN=1 make check` to build all of the changes and execute all
-    of the tests. `AUTO_CLEAN=1` ensures a clean rebuild if your previous build
-    used different parameters. Note that executing all of the tests could take
-    multiple minutes.
-* Run `AUTO_CLEAN=1 ASSERT_STATUS_CHECKED=1 make check` to verify all Status
-    objects are properly checked. This catches missing error handling that can
-    lead to silent data corruption.
-
-### Monitoring make check progress
-* Use `make check-progress` to get machine-parseable JSON progress while
-    `make check` is running. This is useful for Claude Code to monitor long
-    builds without timeout issues.
-* Run `make check` in background, then poll progress:
-    ```bash
-    AUTO_CLEAN=1 make check &
-    # Poll periodically:
-    make check-progress
-    ```
-* The output shows current phase and progress:
-    ```json
-    {"status":"running","phase":"compiling","completed":300,"total":919,...}
-    {"status":"running","phase":"testing","completed":1500,"total":29962,"failed":0,"percent":5,...}
-    {"status":"completed","phase":"testing","completed":29962,"total":29962,"failed":0,"percent":100,...}
-    ```
-* Phases: `compiling` -> `linking` -> `generating` -> `testing` -> `completed`
-* Key fields: `status`, `phase`, `completed`, `total`, `failed`, `percent`
-* When tests fail, `failed_tests` array shows details (up to 10 failures):
-    ```json
-    {"status":"running",...,"failed":3,"failed_tests":[
-      {"test":"cache_test-CacheTest.Usage","exit_code":1,"signal":0,"output":"...test log..."},
-      {"test":"env_test-EnvTest.Open","exit_code":0,"signal":11,"output":"...Segmentation fault..."}
-    ]}
-    ```
-* `exit_code`: non-zero means test assertion failed
-* `signal`: non-zero means test was killed (e.g., 9=SIGKILL, 6=SIGABRT, 11=SIGSEGV)
-* `output`: last 50 lines of test log including error messages and stack traces
-
-### Executing benchmark using db_bench
-* Since the goal is to measure performance, we need to build a release binary
-    using `AUTO_CLEAN=1 DEBUG_LEVEL=0 make db_bench`. If there is an engine
-    crash due to a bug, switch back to a debug build with
-    `AUTO_CLEAN=1 make dbg`; `AUTO_CLEAN=1` handles the release<->debug rebuild
-    automatically.
-
-### Formatting code
-* After making change, use `make format-auto` to auto-apply formatting without
-    interactive prompts (Claude Code friendly).

+# RocksDBLite
+
+RocksDBLite is a project focused on mobile use cases, which don't need a lot of fancy things we've built for server workloads and they are very sensitive to binary size. For that reason, we added a compile flag ROCKSDB_LITE that comments out a lot of the nonessential code and keeps the binary lean.
+
+Some examples of the features disabled by ROCKSDB_LITE:
+* compiled-in support for LDB tool
+* No backupable DB
+* No support for replication (which we provide in form of TransactionalIterator)
+* No advanced monitoring tools
+* No special-purpose memtables that are highly optimized for specific use cases
+* No Transactions
+
+When adding a new big feature to RocksDB, please add ROCKSDB_LITE compile guard if:
+* Nobody from mobile really needs your feature,
+* Your feature is adding a lot of weight to the binary.
+
+Don't add ROCKSDB_LITE compile guard if:
+* It would introduce a lot of code complexity. Compile guards make code harder to read. It's a trade-off.
+* Your feature is not adding a lot of weight.
+
+If unsure, ask. :)

 Even though Windows provides its own efficient thread-pool implementation we chose to replicate posix logic using `std::thread` primitives. This allows anyone to quickly detect any changes within the posix source code and replicate them within windows env. This has proven to work very well. At the same time for anyone who wishes to replace the built-in thread-pool can do so using RocksDB stackable environments.

 For disk access we implemented all of the functionality present within the posix_env which includes memory mapped files, random access, rate-limiter support etc.
-The `use_os_buffer` flag on Posix platforms currently denotes disabling read-ahead log via `fadvise` mechanism. Windows does not have `fadvise` system call. What is more, it implements disk cache in a way that differs from Linux greatly. It's not an uncommon practice on Windows to perform un-buffered disk access to gain control of the memory consumption. We think that in our use case this may also be a good configuration option at the expense of disk throughput. To compensate one may increase the configured in-memory cache size instead. Thus we have chosen  `use_os_buffer=false` to disable OS disk buffering for `WinWritableFile` and `WinRandomAccessFile`. The OS imposes restrictions on the alignment of the disk offsets, buffers used and the amount of data that is read/written when accessing files in un-buffered mode. When the option is true, the classes behave in a standard way. This allows to perform writes and reads in cases when un-buffered access does not make sense such as WAL and MANIFEST.

 We have replaced `pread/pwrite` with `WriteFile/ReadFile` with `OVERLAPPED` structure so we can atomically seek to the position of the disk operation but still perform the operation synchronously. Thus we able to emulate that functionality of `pread/pwrite` reasonably well. The only difference is that the file pointer is not returned to its original position but that hardly matters given the random nature of access.

-# Build RocksDB unit test binaries and run them under gtest-parallel,

-#
-# Hardened version of a simple `make <bin> && gtest-parallel ./<bin>` helper:
-#  * AUTO_CLEAN=1 so the Makefile automatically runs a clean when the build
-#    parameters (DEBUG_LEVEL, sanitizers, ASSERT_STATUS_CHECKED, RTTI, etc.)
-#    have changed since the last build, preventing stale/mixed object files.
-#  * Parallel build with -j<NCORES>, computed the same way the Makefile does.
-#  * Uses the gtest-parallel checked in alongside this script (build_tools/),
-#    so it works regardless of PATH.
-#  * `set -euo pipefail` so any failure stops the script.
-#
-# Run from the repository root.
-#
-# Accepts one or more test binaries (gtest-parallel pools all their test cases
-# into one shared worker queue). The leading non-option arguments are treated as
-# binaries; everything from the first option onward is forwarded to
-# gtest-parallel / the test binaries.
-#
-# Example usage:
-#   build_tools/rocksptest.sh db_test
-#   build_tools/rocksptest.sh db_test -r1000 --gtest_filter=*MixedSlowdown*
-#   build_tools/rocksptest.sh db_test env_test db_basic_test

Maysam Yabandeh	3c0bb7fdd4	Fix SeekForPrev bug with Partitioned Filters and Prefix (#5907 ) Summary: Partition Filters make use of a top-level index to find the partition that might have the bloom hash of the key. The index is with internal key format (before format version 3). Each partition contains the i) blooms of the keys in that range ii) bloom of prefixes of keys in that range, iii) the bloom of the prefix of the last key in the previous partition. When ::SeekForPrev(key), we first perform a prefix bloom test on the SST file. The partition however is identified using the full internal key, rather than the prefix key. The reason is to be compatible with the internal key format of the top-level index. This creates a corner case. Example: - SST k, Partition N: P1K1, P1K2 - SST k, top-level index: P1K2 - SST k+1, Partition 1: P2K1, P3K1 - SST k+1 top-level index: P3K1 When SeekForPrev(P1K3), it should point us to P1K2. However SST k top-level index would reject P1K3 since it is out of range. One possible fix would be to search with the prefix P1 (instead of full internal key P1K3) however the details of properly comparing prefix with full internal key might get complicated. The fix we apply in this PR is to look into the last partition anyway even if the key is out of range.

Iterator verification in stress tests sometimes fail for assertion table/block_based/block_based_table_reader.cc:2973: void rocksdb::BlockBasedTableIterator<TBlockIter, TValue>::FindBlockForward() [with TBlockIter = rocksdb::DataBlockIter; TValue = rocksdb::Slice]: Assertion `!next_block_is_out_of_bound \|\| user_comparator_.Compare(*read_options_.iterate_upper_bound, index_iter_->user_key()) <= 0' failed. It is likely to be linked to https://github.com/facebook/rocksdb/pull/5286 together with https://github.com/facebook/rocksdb/pull/5468 as the former PR makes some child iterator's seek being avoided, so that upper bound condition fails to be updated there. Strictly speaking, the former PR was merged before the latter one, but the latter one feels a more important improvement so I choose to revert the former one for now.

Yanqin Jin	ada6e87f5a	Support loading custom objects in unit tests (#5676 ) Summary: Most existing RocksDB unit tests run on `Env::Default()`. It will be useful to port the unit tests to non-default environments, e.g. `HdfsEnv`, etc. This pull request is one step towards this goal. If RocksDB unit tests are built with a static library exposing a function `RegisterCustomObjects()`, then it is possible to implement custom object registrar logic in the library. RocksDB unit test can call `RegisterCustomObjects()` at the beginning. By default, `ROCKSDB_UNITTESTS_WITH_CUSTOM_OBJECTS_FROM_STATIC_LIBS` is not defined, thus this PR has no impact on existing RocksDB because `RegisterCustomObjects()` is a noop.

Levi Tamasi	222f84e2c3	Fix regression affecting partitioned indexes/filters when cache_index_and_filter_blocks is false (#5705 ) Summary: PR https://github.com/facebook/rocksdb/issues/5298 (and subsequent related patches) unintentionally changed the semantics of cache_index_and_filter_blocks: historically, this option only affected the main index/filter block; with the changes, it affects index/filter partitions as well. This can cause performance issues when cache_index_and_filter_blocks is false since in this case, partitions are neither cached nor preloaded (i.e. they are loaded on demand upon each access). The patch reverts to the earlier behavior, that is, partitions are cached similarly to data blocks regardless of the value of the above option.
