[teiid-issues] [JBoss JIRA] (TEIID-2052) Add Problem/Resolution to query problem using the query plan

[Ramesh Reddy (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12694713#comment-12694713 ] 

Ramesh Reddy commented on TEIID-2052:
-------------------------------------

I think there seems to be two goals here

1) explain the query plan
2) What a translator developer needs to know to implement a pushdown

This issue started out with (2), so IMO we may have to add relevant section as needed to both translator guide/ExecutionFactory javadoc and reference guide.

> Adding content that could be used for query problem resolution.   The initial attachment does the following:
> -  states the query problem (i.e., not pushing down the "IN" clause)
> -  provides the query plan (and debug log) for the query being submitted
> -  provides recommendations for resolving the problem
> -  then indicates how this problem was resolved and what the resulting query plan / debug log
> The idea here is to continue to add other problem scenarios so that this information is really useful for resolving issues.
