> Currently, in DSv2 {{RefreshTableExec}}, we only invalidate metadata cache but not all the caches that referencing the table to be refreshed. This may cause correctness issue if these caches go stale and get queried later.
> Note that since we don't support caching a v2 table yet, we can't recache the table itself at the moment.
