raft-hyperleveldb

Raft backend using HyperDex's HyperLevelDB

Use Case

Drop it in instead of BoltDB if your workload is highly concurrent and write intensive. See their writeup for more details

Example

logStore, _ := rafthyperleveldb.NewHyperLevelDBStore("/path/to/raft/db", rafthyperleveldb.High)

myRaft, _ := raft.NewRaft(config, (*fsm)(c), logStore, logStore, snapshots, transport)
