- don't create contextvars.Context/asyncio.Task in RunnableSeq (not needed as each step creates it if necessary)
- don't run in-memory-saver methods in background threads (no point as they hold the gil)
- avoid calling should_interrupt when no interrupts set
- This should only be used in very specific circunstances, sqlite or
postgres adapters much more appropriate in most circunstances

- Keep old code path for compatibility with existing checkpoints
- Keep a similar order of application of updates, in some cases there will be no visible change
- Update task path for Sends to contain the path of all the parent tasks (multiple parents when a Send task creates another Send)
- That lineage path is used to ensure order of application of updates respects their logical lineage (ie updates from parents always applied before their child tasks)
- Move Interrupt writes to use negative indexes, which allow replacing/shadowing (when task is re-run it may interrupt again, or succeed)
- Runner will now attempt to schedule new Send tasks as soon as the write is received (ie while the originating node is still running)
- Update kafka scheduler to support new Send behavior
* Implement serialization with msgpack library
- encode custom python objects with a msgpack extension type, with constructor path string, and args encoded as nested msgpack doc
* Smaller msgpack extension types
* Update lock files
* lock
* Don't delegate to pydantic json
* Fix kafka serde
- should use our serializer to load, as inputs to subgraphs are serialized using it
* Performance improvements in checkpointer libs
- Use sha1 instead of md5 for hashing (faster in python 3.x)
- Use orjson instead of json for json dumping (sadly can't use for json loading)
* Update tests
* Update
* Use random number instead of hash for get_version_number
* Avoid saving writes for the last task to complete in each step
- only when possible, exceptions for ERROR, INTERRUPT, SEND
* Make Channel.from_checkpoint a regular function
- context manager no longer needed since Context became a managed value
* Use __slots__ for Channels
* Fix for kafka
* Remove unused fil;e
* Add benchmark-fast command for running locally
* Small improvements to jsonplus serializer
* Don't use PregelNode.mapper when schema is a typed dict
- All it would do is create a new copy of same dict
* Avoid copying checkpoint when fetching at beginning of loop
* Fix needs array
* Update tests
