Difference between Partition With Key and Round Robin Partition

Partition With Key: Partition With Key is often also referred to as Hash Partition. This technology of partitioning is taken into use when keys are found to be diverse. If the key is available in very much volume then there is a chance of the existence of large data skew. The Hash Partition is comfortable for data processing in parallel.

Round Robin Partition: Round Robin Partition is the technology of partitioning where the data is evenly distributed on each destination of data partitions. The skew comes out to be zero when the number of partitions completely divides the number of records.
