Take segments in singleton rowset into consideration upon cumulative compaction#1866
Merged
Conversation
…compaction In previous compaction, only rowsets will be taken into consideration. Doing streaming load, the singleton rowset may is made up of many overlapping segments. Scanning these overlapping segments will result in read amplification. To address this problem, overlapping segments should be taken into consideration when doing cumulative compaction to reduce read amplification.
