[ https://issues.jboss.org/browse/TEIID-2584?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-2584: --------------------------------------- You would make a more granular transaction around a an isloading status flag. Whatever process can read the value as false and write it as true and commit in a txn block should do the writing. We've tossed quartz around before, but I can't say off hand if it's a good fit. There are also ejb timers in as 7. I think what you are really getting at is removing the maintenance concern from the processing logic. I think that is the right approach with external materialization (internal too if it's re-targeted at something that has a longer lifespan). The processing logic really should just be concerned if the materialization table is in a readable state and have a known outcome if it's not (wait, error, ignore and read anyway, etc.). -- This message is automatically generated by JIRA.
