grocksdb, RocksDB wrapper for Go

Go Report Card Coverage Status godoc

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.
