Fixes #3229, but the bigger issue is that migrations didn't use transactions at all the whole time 🤯

Now we have a global transaction cut to start a migration - registering both the journal and db_slice callbacks while the datastore is under a global lock and no commands are running

but soon they will preempt. is there any problem with this design have the callbacks preempting?

//! Registers the callback to be called for each change.

could you add a comment that this function should be called in the global transaction only

uint32_t id = next_cb_id_++;
change_cb_arr_.emplace_back(id, std::move(cb));
return id;
lock_guard lk(cb_mu_);

Why do you need it. I thought with global transaction we don't need it anymore

True, but we still need the mutex for deletes, becase we unregister arbitrarily

But for db_slice we don't need it?

Yes, because there is no code path form those callbacks that can unregister itself

Somewhat fragile, I agree

why do we cancel all blocking commands if we migrate only specific slots? we should cancel only the blocking commands only on this slots
