Prashanth Vasudev updated TRAFODION-1798:
-
Description:
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.
