unit of a consistent replication group, contains Consensus Module and Log Module. 2. The State Machine corresponds to the chunk in the CurveBS, and it applies the operations on the chunk (write, delete algorithm. The Copyset module encapsulates the RAFT Node of BRaft and implements the user state machine of BRaft. Take a write request as an example 1. The Client sends the request to the ChunkServer be applied. During apply, BRaft will call the function that we pass in through the user state machine to complete the disk write operation.
