[jira] [Commented] (FLINK-10689) Port UDFs in Table API extension points to flink-table-common

["Bowen Li (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-10689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16672359#comment-16672359 ] 

Bowen Li commented on FLINK-10689:
----------------------------------

Thanks [~twalthr] ! I read the code and your comment makes sense.

As a result of the discussion to parallelize the work, I re-scoped this subtask to only UDFs and created FLINK-10755 to migrate external catalogs. [~xueyu] This task can be proceeded without any dependency now.

An alternative which not only unblocks the hive catalog work and but also doesn't introduce much migration overhead for new code, is that new code/feature or any necessary refactor related to hive and should be written in java and be placed in {{flink-table}}'s java package.

> After FLINK-10687 and FLINK-10688 have been resolved, we should also port the remaining extension points of the Table API to flink-table-common. This includes interfaces for UDFs and the external catalog interface.
> This ticket is for porting UDFs. This jira does NOT depend on FLINK-16088 so it can be started at anytime.
