…onnections (#6702) When using an `AsyncConnectionPool`, connections are most likely† never shared by `_cursor()`. Calling `AsyncConnectionPool.connection()` removes the connection from the pool, so it cannot be used by any concurrent calls. As such, the lock inside `_cursor()` is redundant. If the pool allows more than one connection, then `_cursor()` should be allowed to be concurrently called. As far as I can tell, the only way for that to occur is between `_execute_batch()` and `sweep_ttl()`. In the current setup, if the `sweep_ttl()` operation is slow, then that delays all batch operations. This might be the trigger of the behaviour I was seeing in #6701. † In theory, someone could implement `AsyncConnectionPool` to return a shared connection, but that would be redundant in langgraph.
