[teiid-issues] [JBoss JIRA] (TEIID-2467) thread waits for matview loads

[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2467?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-2467.
-----------------------------------

    Resolution: Done


The issue was actually specific to the handling of time slice expiration.  Changed the time slice exception to be a blocked exception (which somewhat reduces its effectiveness, but that's ok since it's a weak mechanism) to have consistent handling through out the engine - for example TEIID-2430 also requires expired time slice to be a blocked exception since there is no explicit handling for the time slice exception.

> While a matview is loading other threads attempting to query the same matview are held as waiters on the table info lock.
> Also the mat table loading thread is marked is not allowed to throw a blocked exception and is tied to the current loading work.
