------------------------------------------
Summary: Log WARN on large batch sizes
Key: CASSANDRA-6487
URL: https://issues.apache.org/jira/browse/CASSANDRA-6487
Project: Cassandra
Issue Type: Improvement
Reporter: Patrick McFadin
Priority: Minor
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
