Non-blocking mode I/O either transfers at least one byte or returns immediately with an error or end of stream. Non-blocking algorithms refer to use of concurrency without the usual mutual exclusion primitives, guaranteeing that thread operations will not block indefinitely. This is usually handled with atomic value modification (increment/decrement) and/or reading (compare-and-exchange) operations.. It isn't clear which this tag is intended for.

Can SQLAlchemy be configured to be non-blocking?
I'm under the impression that database calls through SQLAlchemy will block and aren't suitable for use in anything other than synchronous code. Am I correct (I hope I'm not!) or is there a way to configure it to be non-blocking?
