From an email with Paul, what's seen in the logs is "Loaded materialized view table #MAT_PARTSVIRTUAL.SUPPLIERINFO from cached contents from another clustered node.". However the only entry that can be present is the current value.

Materialized View cache TTL (in a transformation) does not expire/invalidate the cache automatically ---------------------------------------------------------------------------------------------------- Key: TEIID-1728 URL: https://issues.jboss.org/browse/TEIID-1728 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.4.1 Environment: SOA-P 5.2 ER3, Production configuration Reporter: Paul Nittel With the following transformation SQL, regardless of the time allowed to elapse, the cache does not expire/invalidate. I'm running the production profile. Here's the transformation SQL text: /*+ cache(ttl:30000) */ SELECT PartsSourceA.SUPPLIER_PARTS.SUPPLIER_ID, PartsSourceA.SUPPLIER_PARTS.PART_ID, PartsSourceA.SUPPLIER_PARTS.QUANTITY, PartsSourceA.SUPPLIER_PARTS.SHIPPER_ID, PartsSourceB.SUPPLIER.SUPPLIER_NAME, PartsSourceB.SUPPLIER.SUPPLIER_STATUS, PartsSourceB.SUPPLIER.SUPPLIER_CITY, PartsSourceB.SUPPLIER.SUPPLIER_STATE, CONCAT2(PartsSourceB.SUPPLIER.SUPPLIER_CITY, CONCAT2(', ', PartsSourceB.SUPPLIER.SUPPLIER_STATE)) AS City_State FROM PartsSourceA.SUPPLIER_PARTS, PartsSourceB.SUPPLIER WHERE PartsSourceA.SUPPLIER_PARTS.SUPPLIER_ID = PartsSourceB.SUPPLIER.SUPPLIER_ID It's not expiring/invalidating the cache unless I CALL SYSADMIN.refreshMatView(viewname=>'PartsVirtual.SupplierInfo', invalidate=>true)
