[jira] [Commented] (CALCITE-2046) Support "CREATE FUNCTION" DDL

    [ https://issues.apache.org/jira/browse/CALCITE-2046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16383271#comment-16383271 ] 

Shuyi Chen commented on CALCITE-2046:
-------------------------------------

Hi [~julianhyde], similar to "CREATE TYPE", I am thinking maybe we need add library into the JSON model as well, and keep the fullClassPath for each library added, and this is used to remove all added functions when drop or alter is invoked. What do you think?
