Spark How To Choose Number Of Partitions. Learn how to partition data in spark (pyspark) using coalesce and repartition functions. We can adjust the number of partitions by using transformations like repartition() or coalesce(). Then, we can easily compute the total number of partitions we need and allocate blocks of partitions to different event types. No of partitions = input stage data size / target size; Desired partition size (target size)= 100 or 200 mb; Normally you should set this parameter on your shuffle size(shuffle read/write) and then you can set the number of partition as 128 to 256 mb. These allow increasing or decreasing the number of partitions based on data. Spark partitions can be dynamically changed using repartition() and coalesce() methods.
