Stamatis Zampetakis commented on CALCITE-2741: ---------------------------------------------- Thanks for the clarification [~hhlai1990]! It appears that you have made quite a lot of progress on it. Maybe it would be a good idea to submit a PR so that we can discuss on something more concrete. > Add operator table with Hive-specific built-in functions > -------------------------------------------------------- > > Key: CALCITE-2741 > URL: https://issues.apache.org/jira/browse/CALCITE-2741 > Project: Calcite > Issue Type: New Feature > Components: core > Reporter: Lai Zhou > Assignee: Julian Hyde > Priority: Minor > > [~julianhyde], > I extended the native enummerable implemention of calcite to support Hive sql > ,include UDF、UDAF and all the SqlSpecialOperator,which inspired by apache > Drills. > I modified the parser,type systems,and bridge the hive operator . > How do you think of supporting a direct implemention of hive sql like this? > I think it will be valueable when someone want to migrate his hive etl jobs > to real-time scene. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
