Hi, I am pleased to announce the release of robaho/leveldb <http://www.github.com/robaho/leveldb> It is a key-value store using LSM trees based on my original keydb but has been updated to use an api which is very similar to Google’s C++ LevelDB.
It has some features still under development, like sequence/snapshots and reverse iteration, but it is stable. The performance is excellent. Running tests on the same hardware/os: Google LevelDB fillseq : 5.487 micros/op fillsync : 11305.127 micros/op fillbatch : 2.338 micros/op readrandom : 5.595 micros/op readseq : 0.130 micros/op Robaho LevelDB fillseq : 4.392 micros/op fillsync : 48.591 micros/op fillbatch : 1.220 micros/op fillnoflush : 1.439 micros/op (a special “unsafe” mode) readrandom : 3.649 micros/op readseq : 0.111 micros/op There is also a remote access module to allow sharing of a db across processes (uses gRPC) available robaho/leveldbr <http://www.github.com/robaho/leveldbr> leveldb contains a lock-free for read skip-list data structure which may be useful to some on its own. btw, the race detector reports 0 issues :) Also, I am not certain why the fillsync is so drastically different - the fillsync in robaho/leveldb uses O_SYNC for writing the backing log file - it may be that Google LevelDB uses a higher level that syncs meta data as well. Still, robaho/leveldb has several test to ensure resiliency against failure during write/close. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
