| Description |
|
If ALTER is performed with COPY algorithm (explicitly or implicitly) on a CONNECT table with (potentially) multiple underlying files, the contents of the underlying file gets duplicated. Maybe it would be happening for non-multiple tables too, but MDEV-30909 (COPY algorithm is not supported) doesn't allow to check it.
