Hi, xm_zzc As I know, the principle of Major and Minor data compaction is the same. But Major compaction is based on segment size and Minor compaction is based on segment number.
There is switch named "carbon.enable.auto.load.merge" which will enable compaction when loading data. This only support Minor compaction. Besides, Carbondata support alter table compact [minor | major]. Just specify the compact type you want then it will trigger compaction. Regards. Chenerlu. -- View this message in context: http://apache-carbondata-user-mailing-list.3231.n8.nabble.com/What-is-the-difference-between-Minor-Compaction-Level-1-and-Minor-Compaction-Level-2-tp23p26.html Sent from the Apache CarbonData User Mailing List mailing list archive at Nabble.com.
