Hi dhatchayani, please find the comments below
1. Yes you are right, design document contains this, in datamap status file we will add the mapping of synchrinization of main table and datamap, based on that incremental load is done. 2. I will tell in general, if main table has 10 segments, and then you do lazy load, then first segment of datamap is created with 10segments data, after that 2 loads are done to main table, then for next lazy load, only two segments data of main table are loaded to second segment of datamap. For preaggregate we will keep same behavior as old. 3. Currently also, if you consider the MV datamap, it supports only lazy load. So when the main table data and the datamap data are not synced then the datamao is not selected for pruning, and everytime to decide this, we read the datamap status file and make the plan. So no issues in the reading status. I hope i cleared your doubts, if any more doubts or suggestions, please get back Thank you -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
