[GitHub] [carbondata] manishnalla1994 opened a new pull request #3182: [WIP] [CARBONDATA-3343] Compaction for Range Sort

manishnalla1994 opened a new pull request #3182: [WIP] [CARBONDATA-3343] Compaction for Range Sort
URL: https://github.com/apache/carbondata/pull/3182

Problem: To support Compaction for Range Sort in correct way as earlier it was grouping the ranges/partitions based on taskId which was not correct.

Solution: Combine all the data and create new ranges using Spark's RangePartitioner and using them give each range to one task and apply the filter query to get the compacted segment.
