Struct PersistenceConfig 

pub struct PersistenceConfig {
    pub strategy: PersistenceStrategy,
    pub flush_policy: FlushPolicy,
    pub max_buffered_entries: usize,
}

Configuration parameters for log persistence behavior

Fields

strategy: PersistenceStrategy

Strategy for persisting Raft logs

This controls the trade-off between durability guarantees and performance characteristics. The choice impacts both write throughput and recovery behavior after node failures.

flush_policy: FlushPolicy

Flush policy for asynchronous strategies

This controls when log entries are flushed to disk. The choice impacts write performance and durability guarantees.

max_buffered_entries: usize

Maximum number of in-memory log entries to buffer when using async strategies

This acts as a safety valve to prevent memory exhaustion during periods of high write throughput or when disk persistence is slow.
