[teiid-issues] [JBoss JIRA] Commented: (TEIID-992) Improve update of source costing statistics

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12606612#comment-12606612 ] 

Steven Hawkins commented on TEIID-992:
--------------------------------------

As of 7.4, stats are manually updatable/retrievable through system procedures, see the reference.  However for updates to be persistent, a MetadataRepository is required.  Also there are no gathering routines.  An example of what that may look like is on TEIID-245.

> It is very important that we support the ability to update source statistics at runtime.  This is important due to the changing nature of read/write sources and differences between a development data source and a production data source.  
> The following options should be possible:
>   1) Update model/source statistics on VDB deployment. 
>   2) Update model/source statistics on connector startup.
>   3) Update model/source statistics on at a scheduled time.
>   4) Update model/source statistics upon a manual request.
