Paulo Motta commented on CASSANDRA-11522:
-----------------------------------------
>From my understanding the main concern here was to make the behavior of
>{{batch_size_fail_threshold_in_kb}} consistent between single batch inserts
>and ordinary inserts, but this was already fixed on CASSANDRA-10876, but
>Sylvain will probably be able to clarify best.
We already have {{max_mutation_size_kb}} with a hard limit for mutation size,
so IMO we shouldn't include another artificial limit or warning given it would
be hard to define a soft limit (since it can vary with hardware and load) so it
could potentially confuse more than help (while for batches, a few kilobytes of
multi-partition batches can already be catastrophic so that's why the warn and
fail threshold are important in that case).
> batch_size_fail_threshold_in_kb shouldn't only apply to batch

> I can buy that C* is not good at dealing with large (in bytes) inserts and
> that it makes sense to provide a user configurable protection against inserts
> larger than a certain size, but it doesn't make sense to limit this to
> batches. It's absolutely possible to insert a single very large row and
> internally a batch with a single statement is exactly the same than a single
> similar insert, so rejecting the former and not the later is confusing and
> well, wrong.
> Note that I get that batches are more likely to get big and that's where the
> protection is most often useful, but limiting the option to batch is still
> less useful (it's a hole in the protection) and it's going to confuse users
> in thinking that batches to a single partition are different from single
> inserts.
> Of course that also mean that we should rename that option to
> {{write_size_fail_threshold_in_kb}}. Which means we probably want to add this
> new option and just deprecate {{batch_size_fail_threshold_in_kb}} for now
> (with removal in 4.0).
