Struct WalConfig

Source

pub struct WalConfig {
    pub max_segment_size: usize,
    pub sync_on_write: bool,
    pub max_entries_per_segment: usize,
    pub checkpoint_interval: usize,
}

Expand description

Configuration knobs for WalWriteAheadLog.

Fields§

§max_segment_size: usize

Maximum byte size of a single segment buffer before it is considered full. 0 means unlimited.

§sync_on_write: bool

Whether each write should trigger an immediate sync (no-op for in-memory implementation, included for API completeness).

§max_entries_per_segment: usize

Maximum number of entries per segment before a new one is started. 0 means unlimited.

§checkpoint_interval: usize

How many entries to accumulate between automatic checkpoints. 0 disables auto-checkpointing.
