[jira] [Commented] (CALCITE-1725) Push Extraction function aggragation to druid.

    [ https://issues.apache.org/jira/browse/CALCITE-1725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15963060#comment-15963060 ] 

Julian Hyde commented on CALCITE-1725:
--------------------------------------

Can you fix the hanging close parentheses? They are inconsistent with Calcite code style. " )" does not occur elsewhere in Calcite.

The javadoc comments are not very informative. Mostly they seem to just write the name of the class or interface. But they don't actually explain what a "dimension specification" or "extraction function" is.
