> 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.
