Sorock

A Multi-Raft implementation in Rust language.

Documentation (mdbook)

Features

• Supports Multi-Raft. Mutliple Raft processes can coexist in a single OS process so they can share resources efficiently.
  • Tested with 1000 shards per node.
  • Heartbeats in shards are batched to reduce the network overhead.
• Based on Tonic and efficient gRPC streaming is exploited in log replication and snapshot.
• Efficient default backend implementation using redb.
  • Writes in shards are batched in one transaction.
• Phi Accrual Failure Detector is used for leader failure detection.
  • The adaptive algorithm allows you to not choose a fixed timeout number before deployment and to deploy Raft node in even geo-distributed environment where the latency between nodes isn't identical.
