      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.

      2020-10-10 09:38:10,466 | INFO | [OperationManager-Background-Pool-28] | Horizontal Update Compaction operation started for [ods_oms.oms_wh_outbound_order]

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