Rocksdb3 is a python bindings for rocksdb based on rust wrapper rust-rocksdb and PyO3.
This is a very early proof-of-concept version. Please do not use it in production.
There is already have python-rocksdb, so why create a new wrapper for rocksdb?
- It's fun
- I'm learning Rust, this is my exprience
- PyO3 is fun, too
- Python-rocksdb is not actively maintained
- Python-rocksdb is not released with statically-linked multiple-operating-system-supported wheel binaries
- Debugging out-of-bounds pointers is boring
- precompiled wheel binaries for Linux, Windows, macOS, on python 3.5, 3.6, 3.7, 3.8, 3.9, 3.10
- basic open/put/get/delete/close
- open as secondary instance
- destroy/repair
- iterator
- iterator with specific prefix
- write batch
- options
- open options
- read options
- write options
