Jiayu Shen created CARBONDATA-4034: -------------------------------------- Summary: Improve the time-comsuming of Horizontal Compaction for update Key: CARBONDATA-4034 URL: https://issues.apache.org/jira/browse/CARBONDATA-4034 Project: CarbonData Issue Type: Bug Reporter: Jiayu Shen
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] 2020-10-10 09:50:25,718 | INFO | [OperationManager-Background-Pool-28] | Horizontal Update Compaction operation completed for [ods_oms.oms_wh_outbound_order]. 2020-10-10 10:15:44,302 | INFO | [OperationManager-Background-Pool-28] | Horizontal Delete Compaction operation started for [ods_oms.oms_wh_outbound_order] 2020-10-10 10:15:54,874 | INFO | [OperationManager-Background-Pool-28] | Horizontal Delete Compaction operation completed 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
