Remove session/user scoped materialized views --------------------------------------------- Key: TEIID-5427 URL: https://issues.jboss.org/browse/TEIID-5427 Project: Teiid Issue Type: Task Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 11.1 TEIID-2507 added session scoped materialized views - which are now not well aligned with any other materialization strategy. They have to be unmanaged and internal only. It would be best to completely remove the feature and recommend instead that users create global temporary tables instead.
