> May be create an mv in database A as select from a table in database B, when query the table, we should check all mv on this table, not only in database B. We have a cluster with more than 1,500 databases, and it takes more than 20 seconds to scan each select statement, no matter how simple the SQL. I wonder it should be placed in a specified database? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
