Abstract
Disclosed is a method and system for joining datasets in a distributed computing environment. The system comprises a memoryand a processor. The processoridentifies a skewed dataset from two or more datasets to be joined. The processoridentifies a replication parameter from a configuration file. The processorthen assigns a randomly assigned machine number to each chunk of the skewed dataset owned by the nodes/machines involved in the join operation. The processorforms copies of the non-skewed dataset equal to the replication parameter and adds the copy number to each sample of the copy of the non-skewed dataset formed. Further, the processormerges each non-skewed dataset into the final copy of the non-skewed dataset, forming a single non skewed dataset. The processorthen repeats these steps for all the non-skewed datasets involved in the join operation resulting in generation of merged copies of all the non-skewed datasets and then performs the joining operation.
