Jack Krupansky commented on CASSANDRA-6487:
-------------------------------------------
Is this something important enough that an Ops team might want to monitor in an
automated manner, like with an mbean, for OpsCenter and other monitoring tools?
Maybe count of batch size warnings, largest batch size seen, most recent batch
size over the limit.
> Log WARN on large batch sizes

> Large batches on a coordinator can cause a lot of node stress. I propose
> adding a WARN log entry if batch sizes go beyond a configurable size. This
> will give more visibility to operators on something that can happen on the
> developer side.
> New yaml setting with 5k default.
> {{# Log WARN on any batch size exceeding this value. 5k by default.}}
> {{# Caution should be taken on increasing the size of this threshold as it
> can lead to node instability.}}
> {{batch_size_warn_threshold: 5k}}
