[jira] [Commented] (DRILL-5402) ServerMeta should be updated during the session, if the last has been changed.

["Laurent Goujon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-5402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15949393#comment-15949393 ] 

Laurent Goujon commented on DRILL-5402:
---------------------------------------

Like I mentioned in the pull request for DRILL-3510, I haven't seen this feature implemented by other JDBC drivers, so this might get some sense regarding priority. 

Another thing to consider I believe is that the servermeta object is big (contains all the function names for example), with these functions not changing. So from a protocol point of view, instead of forcing the user to call again {{GetServerMeta}}, user could request just the session, and the driver might combine both the metadata and the session to return the final value? or maybe extend GetServerMeta api with a flag to only return some of the fields?

> DRILL-5301 introduces a new server metadata API. 
> But clients can get from the server the current meta information only once, the next request returns the previous meta even if it was updated. For example, Identifier quote character can be changed by the user via one session.
> It would be good if the session is changed, the "getServerMeta()" will return updated server meta information.
