> Key: CASSANDRA-1426
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1426
> Project: Cassandra
> Issue Type: New Feature
> Affects Versions: 0.7 beta 1
> Reporter: Edward Capriolo
>
> The problem with big rows in 6.0 and 7.0 is they tend to cause OOM with row
> cache and other memory problems. CFStats shows us the MaximumSizedRow but it
> does not show which row this is. Applications that have to scan all the data
> on a node to turn up a big row are intensive and while they are running they
> lower cache hit rate significantly.
> Even though Cassandra 7.0 can accommodate larger rows then 6.X, most use
> cases would never have rows that go over 2 MB.
> Please consider bringing this feature back and setting it low.
> <RowWarningThresholdInMB>10</RowWarningThresholdInMB>. With this admins can
> monitor logs and point out large rows before they get out of hand and cause
> mysterious crashes.
