Hi Akash, 1. For preaggregate table deprecation as part of subtask 7 can specific details be provided in the design doc. 2. Will alter table add partition supported now for table that has timeseries MV datamap ?If not supported it can be updated in the design doc. 3. Would Complex datatypes for timeseries MV datamap be supported ? If not supported it can be updated in the design doc.
