For some reason I thought we had talked about this. Give me queries and
an id block to return results back to a client and we can have parallel
query. I favor reserving four bytes in the header for this. We might
have an issue with transaction context depending on the engine (I need
to look into this still).
You need multiple threads per session, and probably more synchronization
on the session level. This is probably doable?
But I think that it is better to implement serial execution of
statements before concurrent execution. Arbitrary execution order may
sometimes cause transaction deadlocks.
