faust.tables.manager

Tables (changelog stream).

class faust.tables.manager.TableManager(app: faust.types.app.AppT, **kwargs) → None[source]

Manage tables used by Faust worker.

persist_offset_on_commit(store: faust.types.stores.StoreT, tp: faust.types.tuples.TP, offset: int) → None[source]

Mark the persisted offset for a TP to be saved on commit.

This is used for “exactly_once” processing guarantee. Instead of writing the persisted offset to RocksDB when the message is sent, we write it to disk when the offset is committed.
