For instance, > {{WRITE_ID < high_txn_id AND WRITE_ID NOT IN (x, y, ...)}}. Then the > rewriting will do the rest of the work by creating a partial rewriting, where > the contents of the MV are read as well as the new contents from the source > tables. > This mechanism will not work only for ALTER MV... REBUILD, but also for user > queries which will be able to benefit from using outdated MVs to compute part > of the needed results. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
