Nuno Campos d661d528b2 Avoid repeated runtime calls to get_type_hints 
- Replace get_type_hints logic with much simpler implementation which only collects annotated keys (not the annotations themselves)
- Cache annotations in a WeakKeyDictionary

Nuno Campos 0afc4ebda3 Flip default for checkpoint_during 
- Now defaulting to False, ie. saving only the final checkpoint
- All features other than time travel into an intermediate step are supported by checkpoint_during=False so this is a better default for almost all use cases

Nuno Campos 936176eb21 Remove Checkpoint.writes 
- This has been superseded by saving the individual writes of each task through put_writes()
- Removing this speeds up checkpoint operations as it was duplicating data saved elsewhere already
 2025-05-25 19:06:46 -07:00
Nuno Campos 4e8fbe4525 Remove Checkpoint.pending_sends 
- Instead store sends in a Topic channel, removing the need to fetch sends as writes against the parent checkpoint
- Remove deprecated/unused functions in langgraph-checkpoint (will require bumping min range for langgraph-checkpoint in langgraph lib)
- Implement migration of old pending sends in langgraph-checkpoint-postgres
- Ensure parent config of `checkpoint_during=False` checkpoints always points to checkpoints that were also saved

Nuno Campos 85522ec6a6 Pregel: Add NodeBuilder class to replace Channel.subscribe_to

Nuno Campos bc17c3522b Remove old checkpoint test fixtures 
- Now all tests fully migrated to more recent sync_checkpointer and async_checkpointer fixtures for parametrising on checkpointer
- Use sync/async_store fixtures where tests used only in memory store
- Remove unused "should snapshot" check for older versions of langchain core no longer tested against
