--------------------------------------------
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.
