OffsetSyncStore

crabka_replicator::offset_sync_store

Struct OffsetSyncStore 

Source 
pub struct OffsetSyncStore { /* private fields */ }
Expand description

Accumulates OffsetSync records and translates committed source offsets to their corresponding target offsets.

Implementations§

Source§

impl OffsetSyncStore

Source

pub fn ingest(&mut self, s: OffsetSync)

Ingest one offset-sync record, replacing any prior entry for the same (topic, partition, upstream) triple.

Source

pub fn translate( &self, topic: &str, partition: i32, committed: i64, ) -> Option<i64>

Translate a committed source offset to its target offset.

Returns None when:

  • the (topic, partition) pair has no syncs, or
  • committed is below every known upstream offset (un-replicated data).
