Contributing

Feedback and pull requests welcome! If a particular feature of RocksDB is important to you, please let me know by opening an issue, and I'll prioritize it.

Usage

This binding is statically linked with a specific version of RocksDB. If you want to build it yourself, make sure you've also cloned the RocksDB and compression submodules:

git submodule update --init --recursive

Compression Support

By default, support for Snappy, LZ4, Zstd, Zlib, and Bzip2 compression is enabled through crate features. If support for all of these compression algorithms is not needed, default features can be disabled and specific compression algorithms can be enabled. For example, to enable only LZ4 compression support, make these changes to your Cargo.toml:

[dependencies.rocksdb]
default-features = false
features = ["lz4"]

Multithreaded ColumnFamily alternation

RocksDB allows column families to be created and dropped from multiple threads concurrently, but this crate doesn't allow it by default for compatibility. If you need to modify column families concurrently, enable the crate feature multi-threaded-cf, which makes this binding's data structures use RwLock by default. Alternatively, you can directly create DBWithThreadMode<MultiThreaded> without enabling the crate feature.

Switch between /MT or /MD run time library (Only for Windows)

The feature mt_static will request the library to be built with /MT flag, which results in library using the static version of the run-time library. This can be useful in case there's a conflict in the dependecy tree between different run-time versions.
