Tom van der Woerdt commented on CASSANDRA-16232:
------------------------------------------------
It seems that the specific case that's not handled in the batch_size_* settings
is the situation in which a single-partition LWT batch is large. A normal
logged batch to a single partition gets turned into an unlogged batch, but when
that same batch contains a LWT write it's effectively still as heavy as a
logged batch and the limits (or some other configuration key) should probably
apply.
> Need something like batch_size_fail_threshold_in_kb for LWTs

> Subject probably says it all, but basically there's a
> batch_size_warn_threshold_in_kb and batch_size_fail_threshold_in_kb in the
> config but these don't apply to LWTs.
> So of course I found a situation in which devs were doing LWT operations of
> many megabytes :D
> Can we make it possible to forbid these, the same way it can be done for
> batches?
