[jira] [Commented] (FLINK-16079) Primary key should use a deterministic name by default

    [ https://issues.apache.org/jira/browse/FLINK-16079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17037818#comment-17037818 ] 

Jark Wu commented on FLINK-16079:
---------------------------------

Maybe we can use underscore to concat the primary key fields as the primary key name, that will be more readable?

> Right now if a name for primary key is not provided a UUID will be used. We should change it to be a deterministic identifier, e.g. a hash of all columns of the primary key.
