> We should not implement heavy schema change for cooldown, light schema change is done only in fe. We can enable light schema change when creating a table with property light_schema_change = true. light_schema_change is only useful in alter table add value, but not alter table add key, which is still used in old case, so we must change the implement in BE. you can't force user to create table with light_schema_change = true, when he want to use cold data in a old table, it doesn't work. This is used to compatible old table. -- This is an automated message from the Apache Git Service.
