I'll write a mail to coordinate the time :-) > Optimize logical Table API plans in Calcite > ------------------------------------------- > > Key: FLINK-3225 > URL: https://issues.apache.org/jira/browse/FLINK-3225 > Project: Flink > Issue Type: Sub-task > Components: Table API > Reporter: Fabian Hueske > Assignee: Fabian Hueske > > This task implements the optimization of logical Table API plans with Apache > Calcite. The input of the optimization process is a logical query plan > consisting of Calcite RelNodes. FLINK-3223 translates Table API queries into > this representation. > The result of this issue is an optimized logical plan. > Calcite's rule-based optimizer applies query rewriting and optimization > rules. For Batch SQL, we can use (a subset of) Calcite’s default optimization > rules. > For this issue we have to > - add the Calcite optimizer to the translation process > - select an appropriate set of batch optimization rules from Calcite’s > default rules. We can reuse the rules selected by Timo’s first SQL > implementation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
