[teiid-issues] [JBoss JIRA] (TEIID-1801) Async Event Processing: Reset and Re-run plan

[Mark Addleman (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12646067#comment-12646067 ] 

Mark Addleman commented on TEIID-1801:
--------------------------------------

Regarding the time window & re-runing:  I don't particularly care if these options are exposed to the client via a method or a query hint as long as the data is available to the translator via the execution context.  My gut feel is that a query hint is conceptually better.

Regarding the result set caching:  This issue seems dominated by internal Teiid considerations.  My only input is that the result sets are potentially large so keeping the clause open may not a good solution.  I'm perfectly comfortable with requiring a hint to indicate that a cache should be used.

> In order to processing a stream of events aggregated within a specified time window, the engine should provide some way of specifying the time period (analogous to a window), reset and re-rerun the plan for every time period.  There should also be an engine to translator callback indicating that the plan has been reset as opposed to closed.
