Hi all,
I’d like to propose the single replica compaction in doris。 Since same operations are performed on all replicas in compaction, which leads to a lot of resource comsumption。I plan to support single replica compaction to reduce the usage of CPU and IO in cluster, do compaction in one replica and Other replicas only need to copy data from it. I will introduce some random factors so that different replica of a tablet will do compaction at different times, once a replica begin compaction, other related replicas just wait and then copy result file。 -- Best Regards.
