adelapena opened a new pull request, #2321: URL: https://github.com/apache/cassandra/pull/2321
The patch adds a new guardrail for partition size that is checked when writing a sstable (flush, compaction, etc.) Triggering the failure threshold will emit an ERROR log message and a diagnostic event, but it won't abort the sstable write operation. This guardrail replaces the `compaction_large_partition_warning_threshold` property, which is now marked as deprecated. Both checks will exist until we remove `compaction_large_partition_warning_threshold` on the next major. The reason for keeping both properties and not just renaming `compaction_large_partition_warning_threshold` to `partition_size_warn_threshold` is that the behaviour, log messages, etc. are slightly different. It's worth mentioning that the existing `compaction_large_partition_warning_threshold`: * Isn't actually triggered only on compaction, but on any sstable write. * Cannot be dynamically updated. * Doesn't emit any kind of diagnostic events. -- This is an automated message from the Apache Git Service.
