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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
