grocksdb, RocksDB wrapper for Go

This is a Fork from tecbot/gorocksdb. I respect the author work and community contribution. The LICENSE still remains as upstream.

Why I made a patched clone instead of PR:

• Supports almost C API (unlike upstream). Catching up with latest version of Rocksdb as promise.
• This fork contains no defer in codebase (my side project requires as less overhead as possible). This introduces loose convention of how/when to free c-mem, thus break the rule of tecbot/gorocksdb.

Install

Prerequisite

• librocksdb
• libsnappy
• libz
• liblz4
• libzstd
• libbz2 (optional)

Please follow this guide: https://github.com/facebook/rocksdb/blob/master/INSTALL.md to build above libs.

Build

After installing both rocksdb and grocksdb, you can build your app using the following commands:

CGO_CFLAGS="-I/path/to/rocksdb/include" \
CGO_LDFLAGS="-L/path/to/rocksdb -lrocksdb -lstdc++ -lm -lz -lsnappy -llz4 -lzstd" \
  go build

Or just:

go build // if prerequisites are in linker paths

If your rocksdb was linked with bz2:

CGO_LDFLAGS="-L/path/to/rocksdb -lrocksdb -lstdc++ -lm -lz -lsnappy -llz4 -lzstd -lbz2" \
  go build
