             Summary: Support Transactions for DDL statements
                 Key: TRAFODION-1798
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1798
             Project: Apache Trafodion
          Issue Type: New Feature
            Reporter: Prashanth Vasudev


This work to support transaction for DDL operations started before Trafodion became part of incubation as Apache Trafodion.  The initial link to the blueprint is https://blueprints.launchpad.net/trafodion/+spec/dtm-ddl-support

Some of the implementation to support this feature is already in code base, however there are some more additional changes needed to support completely.
Additional changes include:

1. SQL executor changes to leverage transactional DDL support by transaction manager.
2. Issue with simultaneous transactional update to the table followed by drop. This manifests as a hang when a drop schema is performed.
3. Recovery in case of HA failure scenario.
