Jonathan Ellis commented on CASSANDRA-6487: ------------------------------------------- There's essentially no performance gain from batching across multiple partitions. > 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 > Assignee: Lyuben Todorov > Priority: Minor > Fix For: 2.0.8 > > Attachments: 6487-cassandra-2.0.patch, 6487-cassandra-2.0_v2.patch > > > 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}} -- This message was sent by Atlassian JIRA (v6.2#6252)
