In one embodiment, a system includes at least one processor and logic configured to receive a request to process data stored in one or more index records in a keyed index of a database, determine an active key range for the one or more index records, and group the one or more index records into a number of groups for parallel processing thereof. In another embodiment, a method for utilizing a keyed index includes receiving a request to process data stored in index records in a keyed index of a database, determining an active key range for the index records, grouping the index records into a number of groups without prior knowledge of a key distribution for dividing the one or more index records into key ranges for parallel processing thereof; and processing the groups of index records in parallel.
