1. A method implemented by a computing device comprising:

  • partitioning a database with a first partition function; and

    repartitioning the database by;

    creating a record of key membership for data entries located in partitions existing at a time of repartitioning;

    adding one or more new partitions associated with a second partition function;

    defining a composite partition function for subsequent database operations configured to;

    apply the first partition function for data having key values found in the record of key membership; and

    apply the second partition function for data having key values not found in the record of key membership, wherein the repartitioning is performed such that the data entries located in partitions existing at the time of repartitioning keep their respective locations.
