PARTITION KEY ADJUSTMENT BASED ON QUERY WORKLOAD

Abstract:

Disclosed is a computer-implemented method to adjust partition keys. The method includes identifying a target table that is a target of a query, the target table including a set of initial partitions. The method also includes determining a set of common queries, wherein each of the common queries are configured to retrieve data from the target table. The method further includes identifying a plurality of core ranges. The method includes merging the core ranges into a new set of partitions. The method further includes setting, in response to the merging, updated partition keys. Further aspects of the present disclosure are directed to systems and computer program products containing functionality consistent with the method described above.
