Is your proposal related to a problem?

Currently, mutations are not supported for MySQL. Due to which, I am unable to upgrade to hasura 3.

Describe the solution you'd like

Complete mutation capabilities like it's supported for Postgres.

Thanks for this, @pravinprabhat — I've added a label for triage, but this is unlikely to be picked up.

The best suggestion I can offer is for you to:

1. Continue using v2.
2. Use a Lambda connector to write the mutations against the DB.
