SOFAJRaft is a production-level, high-performance Java implementation based on the RAFT consistency algorithm that supports MULTI-RAFT-GROUP for high-load, low-latency scenarios. With SOFAJRaft you can focus on your business area. SOFAJRaft handles all RAFT-related technical challenges. SOFAJRaft is very user-friendly, which provides several examples, making it easy to understand and use.


  • Leader election and priority-based semi-deterministic leader election
  • Log replication and recovery
  • Read-only member (learner)
  • Snapshot and log compaction
  • Cluster membership management, adding nodes, removing nodes, replacing nodes, etc.
  • Mechanism of transfer leader for reboot, load balance scene, etc.
  • Symmetric network partition tolerance
  • Asymmetric network partition tolerance
  • Fault tolerance, minority failure doesn't affect the overall availability of system
  • Manual recovery cluster available for majority failure
  • Linearizable read, ReadIndex/LeaseRead
  • Replication pipeline
  • Rich statistics to analyze the performance based on Metrics
  • Passed Jepsen consistency verification test
  • SOFAJRaft includes an embedded distributed KV storage implementation


Compile requirement: JDK 8+ and Maven 3.2.5+ .



How to contribute


SOFAJRaft was ported from Baidu's braft with some optimizing and improvement. Thanks to the Baidu braft team for opening up such a great C++ RAFT implementation.
