[teiid-issues] [JBoss JIRA] Commented: (TEIID-900) Refine option no cache behavior

[Steven Hawkins (JIRA)]

    [ https://jira.jboss.org/jira/browse/TEIID-900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12499117#action_12499117 ] 

Steven Hawkins commented on TEIID-900:
--------------------------------------

We should also require a no cache hint even for loads - e.g. select ... into st from x option nocache x.  Detecting a staging table into target requires the use of the select into syntax.

> Currently specifying option no cache with a particular group name cascades fully through all materialized views.  It would be better if it only applied to a single level.  Simply specifying option no cache without any specific groups would continue to behave the same way as it does currently, which bypasses cache for all materialized views.
> The materialized view scripts should be changed to SELECT ... INTO ... FROM x OPTION NOCACHE x so that the loads can take advantage of intermediate materialized view layers.
