Sean Bridges created CASSANDRA-8177: ---------------------------------------
Summary: sequential repair is much more expensive than parallel repair Key: CASSANDRA-8177 URL: https://issues.apache.org/jira/browse/CASSANDRA-8177 Project: Cassandra Issue Type: Bug Reporter: Sean Bridges This is with 2.0.10 The attached graph shows io read/write throughput (as measured with iostat) when doing repairs. The large hump on the left is a sequential repair of one node. The two much smaller peaks on the right are parallel repairs. This is a 3 node cluster using vnodes (I know vnodes on small clusters isn't recommended). Cassandra reports load of 40 gigs. We noticed a similar problem with a larger cluster. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
