Methods, systems, and computer program products are provided for generating application-aware data partitioning to support parallel computing. A label for a user defined data partitioning (UDP) key is generated by a labeling process to configure data partitions of original data. The UDP is labeled by the labeling process to include at least one key property excluded from the original data. The data partitions are evenly distributed to co-locate and balance the data partitions and corresponding computations performed by computational servers. A data record of the data partitions is retrieved by performing an all-node parallel search of the computational servers using the UDP key.
