Next: https://github.com/facebook/rocksdb/issues/14959. This PR adds `include/rocksdb/index_factory.h` as a source-compatible set of new names over the current experimental UDI API: - `IndexFactoryBuilder` -> `UserDefinedIndexBuilder` - `IndexFactoryIterator` -> `UserDefinedIndexIterator` - `IndexFactoryReader` -> `UserDefinedIndexReader` - `IndexFactoryOptions` -> `UserDefinedIndexOption` - `IndexFactory` -> `UserDefinedIndexFactory` - `kIndexFactoryMetaPrefix` -> `kUserDefinedIndexPrefix` This intentionally does not change table building, table reading, SST format, OPTIONS parsing, or the C API. Existing `UserDefinedIndexFactory` subclasses that only implement the old `NewBuilder()` and `NewReader(Slice&)` shape still compile and work through the new `IndexFactory` name. Validation: - `build_tools/rockstest.sh table_test --gtest_filter='IndexFactoryCompatibilityTest.*'` - `make check-sources` - GitHub Actions PR matrix passed on the current head Pull Request resolved: https://github.com/facebook/rocksdb/pull/14954 Reviewed By: jaykorean Differential Revision: D114358164 Pulled By: xingbowang fbshipit-source-id: 5c830dc1f9dfcf11373423a03103a595fd8ad921
RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

internal APIs may be changed without warning.
