Subject [jira] [Created] (HIVE-17306) Support MySQL InnoDB Cluster
Date Sat, 12 Aug 2017 14:05:00 GMT
Shawn Weeks created HIVE-17306:

             Summary: Support MySQL InnoDB Cluster
                 Key: HIVE-17306
             Project: Hive
          Issue Type: Improvement
            Reporter: Shawn Weeks
            Priority: Minor

To support high availability of the Hive Metastore using a highly available database is required.
To support the MySQL InnoDB Cluster it looks like we're just missing a couple primary keys
as we were already using InnoDB tables for the metastore. It looks like it's primarily the
transaction tables that don't have primary keys like TXN_COMPONENTS and COMPLETED_TXN_COMPONENTS.
The primary keys can be surrogate sequences if there really is no unique identifier in these
