Coracle.Raft

Clusterize your functionality and build your own replicated state machine using this completely extensible implementation of the Raft consensus algorithm in .NET.

Features

• Control important functionality
  • Extend Coracle.Raft.Engine.Remoting.IOutboundRequestHandler for Outbound Remote Operations without any restrictions on protocols and data-transfer formats
  • Extend Coracle.Raft.Engine.Discovery.IDiscoveryHandler for initial discovery of other Coracle nodes
  • Extend Coracle.Raft.Engine.Command.IStateMachineHandler for maintaining the State Machine, i.e your cluster's core state functionality
  • Extend Coracle.Raft.Engine.States.IPersistentStateHandler for managing crucial persistent properties, state snapshots, and the replicated log using any data storage technology
• Supports configuration changes using the cited "Joint-Consensus" approach
• Supports quick catch-up of newly added nodes using InstallSnapshotRPC
• Fine-grained control over internal processing using IEngineConfiguration settings
• Extensive and rich logging of all internal workflows
  • Control log Level and integrate extensible Log sinks
  • For consistency, IActivityLogger can be used again for capturing logs from implementations of the aforementioned handlers
• Easy DI registration
