Hi, Stamatis Because we have a number of internal clusters already using and installing presto. And we want use calcite to optimize the parser and push it down to presto, spark and other calculation engines or olaps. Utilize the sql optimization function of calite in combination with distributed computing engines or distributed olaps such as presto. In this way, each performance can be exerted.
