Subject [jira] [Created] (CASSANDRA-6487) Log WARN on large batch sizes
Date Sat, 14 Dec 2013 00:15:08 GMT
Patrick McFadin created CASSANDRA-6487:
------------------------------------------

             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
