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.
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 --recursiveBy 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"]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.
RocksDB's build, unlike Cargo, will default to setting -march=native, which
generate code that fully takes advantage of build machine's CPU's features.
This may create a binary that isn't compatible with other CPUs on the same
architecture. For example, building on a machine with AVX512 support will create
a binary that fails with SIGILL on machines without AVX512.
Set the portable feature on this crate to pass PORTABLE=1 to RocksDB's build,
which will create a portable binary at the cost of some performance.
