Hi Monty,<br>
<br>
Thank you for the feedback. I'm excited about getting these patches
upstream as everyone will be able to benefit from them.<br>
<br>
Thanks,<br>

<pre wrap="">Hi Folks,
I'm working on adding support for MySQL Cluster to the core OpenStack
services. This will enable the community to benefit from an
active/active, auto-sharding, and scale-out MySQL database. My approach
is to have a single configuration setting in each core OpenStack service
in the oslo.db configuration section called mysql_storage_engine that
will enable the logic in the SQL Alchemy or Alembic upgrade scripts to
handle the differences between InnoDB and NDB storage engines
respectively. When enabled, this logic will make the required table
schema changes around:
* Row character length limits 65k -> 14k
* Proper SQL ordering of foreign key, constraints, and index operations
* Interception of savepoint and nested operations
By default this functionality will not be enabled and will have no
impact on the default InnoDB functionality. These changes have been
tested on Kilo and Mitaka in previous releases of our OpenStack
distributions with Tempest. I'm working on updating these patches for
upstream consumption. We are also working on a 3rd party CI for
regression testing against MySQL Cluster for the community.
The first change set is for oslo.db and can be reviewed at:

Yay!
(You may not be aware, but there are several of us who used to be on the
MySQL Cluster team who are now on OpenStack. I've been wanting good NDB
support for a while. So thank you!)
