Summary: Distributed query engine
Key: KYLIN-4214
URL: https://issues.apache.org/jira/browse/KYLIN-4214
Project: Kylin
Issue Type: Sub-task
Components: Query Engine
Reporter: yiming.xu
Sql through calcite analysis optimization will generate a tree of OLAP rel,
and spark's catalyst is also generated by parsing SQL after a tree,
automatically optimized to become a dataframe to calculate, if the plan of
calcite can be converted into a spark plan, then we will achieve
distributed computing, calcite is only responsible for parsing SQL and
returning result sets, reducing the pressure on the kylin server side.
