oslo.db is apparently required, but it is unclear what kind change is required in each project.
It should start in oslo.db or as a cross project spec.

Bug description:
  oslo.db assumes that a MySQL database can only have a storage engine
  of InnoDB. This causes complications for OpenStack to support other
  MySQL storage engines, such as MySQL Cluster (NDB). Oslo.db should
  have a configuration string (i.e. mysql_storage_engine) in the oslo_db
  database group that can be used by SQLalchemy, Alembic, and OpenStack
  to implement the desired support and behavior for alternative MySQL
  storage engines.

  I do have a change-set patch for options.py in oslo_db that will add
  this functionality. I'll post once I'm added to the CLA for OpenStack.
