Struct WalConfig 

Source 
pub struct WalConfig {
    pub sync_policy: SyncPolicy,
    pub snapshot_seq: u64,
}
Expand description

WAL writer configuration.

Fields§

§sync_policy: SyncPolicy

Flush and fsync schedule.

§snapshot_seq: u64

Highest WAL sequence covered by the snapshot this file extends.

Written into the file header on a fresh file, and used to seed last_sequence so the first appended entry receives sequence snapshot_seq + 1. On reopen, the on-disk header is the source of truth and the config value is ignored — recovery never moves a snapshot watermark backward.

Implementations§
