Frequently Asked Questions

Log compaction is a cleanup policy that retains only the most recent value for each key in a topic. Instead of deleting messages by time, it keeps the latest state of each record, making it ideal for state stores and changelog topics.

Use log compaction for topics that represent the current state of a key (like database changelogs, configuration data, or Kafka Streams state stores). Use time-based retention for event streams where you need to keep all events for a period.

The dirty ratio is the percentage of log data that contains duplicate keys and is eligible for compaction. A high dirty ratio means more storage is being used than necessary and compaction may be falling behind.

KLogic tracks compaction thread activity, dirty ratios, segment sizes, and compaction throughput. It alerts when compaction falls behind or when topics are using excessive storage due to compaction issues.

Common causes include insufficient compaction threads, large segment sizes, high write throughput, or broker resource constraints. KLogic identifies bottlenecks and provides optimization recommendations.

Yes, KLogic allows you to monitor compaction metrics for individual topics or groups of topics. You can set up alerts specific to critical compacted topics like state stores or configuration topics.
