Forcing the use of AWS Aurora Parallel Query

Get Help
1

AWS Aurora RDS for MySQL has a feature known as Parallel Query which will improve latencies for Analytics Workloads.

We can force Aurora to use Parallel Query for a session using
SET SESSION aurora_pq_force = on;

which will ensure that it is used for all the queries run in that session.

Is there a way to ensure that all queries going from Metabase use this setting by configuring anywhere.
I could not even use this as a separate SQL statement while building dashboards.

Or perhaps try using 1 instead of on.

Multi-statements are currently not supported, though it's possible to enable for MySQL:
