Erick Ramirez commented on CASSANDRA-9643:
------------------------------------------
The previous message format included the offending partition key (yep, that's a
43GB partition in production):
{noformat}
INFO CompactionController Compacting large row acmeKS/veryWideTable:key5678
(45262476248 bytes) incrementally
{noformat}
It would be great if we could maintain this format since it makes it easy to
identify the table and partition without having to trawl through the cfstats
output.
> Warn when an extra-large partition is compacted

> Key: CASSANDRA-9643
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9643
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Jonathan Ellis

> Fix For: 2.1.x

>
> We used to log a warning when compacting an extra-large row
> (CompactionController.getCompactedRow) but took that out as part of
> CASSANDRA-6142. Let's add back a warning. (Perhaps in SSTW.append, since
> MetadataCollector.update doesn't know the partition key and we will want to
> include that in the log.)
> Row size should be configurable in cassandra.yaml and default to 100MB.
