Subject [jira] [Created] (IGNITE-12248) Apache Calcite based query execution engine
Date Mon, 30 Sep 2019 15:32:00 GMT
Igor Seliverstov created IGNITE-12248:

             Summary: Apache Calcite based query execution engine
                 Key: IGNITE-12248
                 URL: https://issues.apache.org/jira/browse/IGNITE-12248
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Igor Seliverstov
            Assignee: Igor Seliverstov

Currently used H2 based query execution engine has a number of critical limitations Which
do not allow to execute an arbitrary query.

The ticket aims to show potential of a new, Calcite based, execution engine which may act
not worse than current one on co-located queries, provide a boost for queries, using distributed
joins, and provide an ability to execute arbitrary queries, requiring more than one map-reduce
step in execution flow.
