MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Virus-Checked: Checked by ClamAV on apache.org I would think that compaction_throughput_kb_per_sec does have indirect impact on disk IO. High number means or setting it to 0 means there is no throttling on how much IO is being performed. Wouldn't it impact normal reads from disk during the time when disk IO or util is high which compaction is taking place? -- View this message in context: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/how-does-compaction-throughput-kb-per-sec-affect-disk-io-tp6831711p6832308.html Sent from the cassandra-user@incubator.apache.org mailing list archive at Nabble.com.
