I don't doubt the need to remove the v1 code,My main focus is to *keep Doris stable* while removing the v1 code. 1 First, How to trigger the convert, can you briefly describe the main process? Is it automatic or requires manual operation? 2 Second, what is the cost of converting(will it take up too much cpu and disk IO?), especially when a Doris cluster has tens of millions tablets.
