1. An apparatus, comprising:

  • a reception module to retrieve multiple rows of a database in response to receiving a request to execute an aggregate user defined function (UDF) over the multiple rows; and

    a processor to sort each of the multiple rows into common groups, to group together individual ones of the multiple rows that share one of the common groups, and to send UDF execution requests to apply the aggregate UDF to aggregate buffers of the common groups to produce an aggregate result, so that one of the UDF execution requests and one context switch are used to process each of the aggregate buffers used within one of the groups to provide at least one intermediate result that can be processed to form the aggregate result.
