[teiid-issues] [JBoss JIRA] (TEIID-2253) Multi-source issues

[ https://issues.jboss.org/browse/TEIID-2253?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-2253: --------------------------------------- I've been spending some time with trying to make the multi-source logic more consistent as part of this overhaul. It looks like we'll end up with a very different implementation than we do now. Of current logic is based upon the idea that the plans will be mostly pushdown/simple such that the effect of the multi-source operation can be localized to the access nodes. In general this is not the case, for example if multi-source tables end up on both sides of a join, in a with clause, on both sides of an insert into, etc. the current logic does not correctly interpret the intent. The approach of disabling all ordering/aggregate capabilities is also not ideal as it should only affect the user query. -- This message is automatically generated by JIRA.
