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.
