Jiayu Shen updated CARBONDATA-4034:
-----------------------------------
Description:
In the update flow, horizontal compaction will be significantly slower when
updating with a lot of segments(or a lot of blocks).
There is a case whose costing is as shown in the log.

In this PR, we optimize the process between second and third row of the log,
by optimizing the method _performDeleteDeltaCompaction_ in horizontal
compaction flow.
