> 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:
> 0. Enable existing transactional DDL support in transaction manager. Also enable corresponding regression test.
> 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.
