Controls when snapshot_latest is saved automatically.
There are two kinds of snapshots:
snapshot_latest: A single mutable snapshot that is overwritten on each save. Used to
resume the most recent conversation state (e.g. after a crash or restart). Always reflects
the last saved point in time.
Immutable snapshots: Append-only snapshots with unique IDs (UUID v7), created only when
snapshotTrigger fires. Used for checkpointing — you can restore to any prior state, not
just the latest.
SaveLatestStrategy controls how frequently snapshot_latest is updated:
'invocation': after every agent invocation completes (default; balances durability and I/O)
'message': after every message added to the conversation (most durable, highest I/O)
'trigger': only when a snapshotTrigger fires (or manually via saveSnapshot)
