Loic Lambiel commented on CASSANDRA-9683: ----------------------------------------- I've attached the schema and cfstats so you could have a better idea. I didn't had the opportunity yet to test it on a single node config. FYI our config is logs on SSD and data on 8* JBOD SATA disks. This cluster serves our S3 compatible object storage (http://pithos.io). > Get mucher higher load and latencies after upgrading from 2.1.6 to cassandra > 2.1.7 > ---------------------------------------------------------------------------------- > > Key: CASSANDRA-9683 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9683 > Project: Cassandra > Issue Type: Bug > Environment: Ubuntu 12.04 (3.13 Kernel) * 3 > JDK: Oracle JDK 7 > RAM: 32GB > Cores 4 (+4 HT) > Reporter: Loic Lambiel > Assignee: Ariel Weisberg > Fix For: 2.1.x > > Attachments: cassandra.yaml, cfstats.txt, os_load.png, > pending_compactions.png, read_latency.png, schema.txt, system.log, > write_latency.png > > > After upgrading our cassandra staging cluster version from 2.1.6 to 2.1.7, > the average load grows from 0.1-0.3 to 1.8. > Latencies did increase as well. > We see an increase of pending compactions, probably due to CASSANDRA-9592. > This cluster has almost no workload (staging environment) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
