Slides: https://www.slideshare.net/DataStax/the-missing-manual-for-leveled-compaction-strategy-wei-deng-datastax-cassandra-summit-2016 | In this presentation, we will look into JIRAs, JavaDocs and system log entries to gain a deeper understanding on how LCS works under the hood. We will explain what scenarios don't work well for LCS and (more importantly) why. We will leverage legacy TRACE/DEBUG level log for compaction related objects as well as some newer compaction logging information introduced in C* 3.6 (CASSANDRA-10805) to gain better insights.
