[jira] [Created] (HIVE-17306) Support MySQL InnoDB Cluster

Shawn Weeks created HIVE-17306:
----------------------------------

             Summary: Support MySQL InnoDB Cluster
                 Key: HIVE-17306
                 URL: https://issues.apache.org/jira/browse/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 tables.
