Is that true? The default limit on concurrent function executions is 1000. The existing Aurora (MySQL) should be able to handle cycling through those connections without issue.

It’s not that the DB servers can’t handle it, it’s that establishing a connection is slower than re-using an existing one.

You also forgo certain optimizations within the DB designed to make fetching things for the given connection/scope faster, such as temp tables.
