In order to support split queries for map-reduce jobs, we need a way to send queries to specific shards. But we cannot assume that there will be physical keyspace_id column in the table, which will prevent us from specifying a keyrange on it. So, we introduce the KEYRANGE construct which is a boolean expression that VTGate can use to match the range to a set of shards. Since the construct is not understood by VTTablet or MySQL, VTGate will also strip the construct before passing the query down. |
