ThreadTTLConfig

Action taken when a thread exceeds its TTL.

• "delete": Remove the thread and all its data entirely.
• "keep_latest": Prune old checkpoints but keep the thread and its latest state.

Default TTL (time-to-live) in minutes for checkpointed data.

Interval in minutes between sweep iterations. If omitted, a default interval will be used (typically ~ 5 minutes).

Maximum number of threads to process per sweep iteration. Defaults to 1000.
