Original topic: 分区表要改列类型DDL要做reorg,TiDB为什么一直不支持呢?
The change column type DDL was already released in version 5.1, but even until version 7.5, partitioned tables are still not supported. Why is it always a half-finished project? Is there a plan to support it? Or what is the reason for not planning to support it?
Plans will be made and tackled one by one.
It feels like TiDB hasn’t been fully defined yet and is constantly iterating.
It should be in the plan…
Just needs to be scheduled~
After internal friction, restart and be patient.
Have you considered handling it indirectly? Add a column, then delete a column!
How should this kind of data be handled?
Queries, inserts, or updates are all possible. Please give a thumbs up if you’re satisfied!
This will require stopping the business, and if there is a lot of data, the time might be quite long, which is probably unacceptable.
