| Description |
|
Add a configuration option for a multi um deployment to always use the local exemgr rather than round robinning between the exemgrs. The system default value should remain as round robin as this can still be useful if a customer does not use the multiple mysqld instances. |

This type of query control is requested by a customer. I don't know if it can be done as part of this feature. https://support.mariadb.com/view.php?id=13592 Ok, so say we set it so UM2 does not route queries. And all the others queries came in on UM1. Would UM1 route queries to UM3, and if a UM4 existed to UM4, but not to UM2? |

Implementing this feature by updating the ExeMgr Ip address accordingly in the Columnstore.xml, so no code changes are required at the connector leave. Also will look at implementing to allow based on the comment from 2017-02-28. |
