> 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
> Assignee: Prashanth Vasudev
> Attachments: TransactionsDDL_Apache.pdf
>
>
> 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.
