See full text

Storing data in a distributed database management system. The distributed database management system includes a first set of database tables, wherein data of a logical database table is distributed among the first set of database tables according to a first distribution key. A second set of database tables is maintained using a second distribution key that is different from the first distribution key. Furthermore, at least one performance metric value for the stored query when executing a query is maintained, and the second distribution key is determined based on the at least one performance metric value.
