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 the [Snappy](https://github.com/google/snappy), [LZ4](https://github.com/lz4/lz4), [Zstd](https://github.com/facebook/zstd), [Zlib](https://zlib.net), and [Bzip2](http://www.bzip.org) 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 The underlying RocksDB does allow 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 crate feature called `multi-threaded-cf`, which makes this binding's data structures to use RwLock by default. Alternatively, you can directly create `DBWithThreadMode` without enabling the crate feature.
