>
> 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}}
