[jira] [Commented] (LENS-1019) Return same handle for repeated query from same user

["Lavkesh Lahngir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LENS-1019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15272272#comment-15272272 ] 

Lavkesh Lahngir commented on LENS-1019:
---------------------------------------

1. There is no need to check for sync queries, because they are very short lived. Or there will be a timeout of a fixe duration which will cancel the query which are not completed. 
2. We have to check if the user provided conf is the same for the previous query. 
QueryContext class has a lensconf which is updated with all the configurations. So the user-conf is merged in the lensConf. There is no separate way to get the user-conf. We can store the user-conf in QueryContext or if we want to optimise, we could just store a md5-hash of the conf.

> If query is repeated from user - with same query, same name, same conf on the same session
> and earlier is still queued or running, then return the same handle.
