> Key: TRAFODION-25
> URL: https://issues.apache.org/jira/browse/TRAFODION-25
> Project: Apache Trafodion
> Issue Type: Bug
> Reporter: Qifan Chen

> Labels: performance

> In Trafodion, insert, delete and update operators do not use a specialized cost method that model the true operation involved.
> As a result, these operators can be assigned a zero cost and the query plan may not be optimal. In one example, a delete query against a partitioned table may get a serial plan.
