Struct StateMachineWorker 

Source 
pub struct StateMachineWorker<T: TypeConfig> { /* private fields */ }
Expand description

State Machine Worker

Decouples state machine apply operations from CommitHandler. Runs in independent task, allowing apply_chunk I/O to not block commit processing.

On shutdown:

  • Drains remaining entries from sm_apply_rx until channel closes
  • Completes all pending applies before shutdown
  • This ensures no data loss and all results are propagated to Leader
