-----------------------------------------
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.
