Original Pull Request: https://github.com/langchain-ai/langgraph/pull/6784

State: closed
Merged: Yes

Summary

  • Add "keep_latest" to ThreadTTLConfig.strategy to match langgraph-api support for pruning old checkpoints while retaining the thread and its latest state
  • Add sweep_limit to ThreadTTLConfig where the API actually reads it (was previously a no-op on CheckpointerConfig)
  • Regenerate schema.json / schema.v0.json

Test plan

  • make format && make lint passes
  • make test passes (85/85)
