Indhumathi Muthumurugesh updated CARBONDATA-4183:
-------------------------------------------------
Description: Currently, number of tasks for partition table local sort
load, is decided based on input file size. In this case, the data will not be
properly sorted, as tasks launched is more. For compaction, number of tasks is
equal to number of partitions. If data is huge for a partition, then there can
be chances, that compaction will fail with OOM with less memory configurations.
