Ariel Weisberg commented on CASSANDRA-9683: ------------------------------------------- How are you getting fraction of a millisecond latency operating on 300 megabyte rows? What is the workload that latency is being measured for in read/write? Can you provide more specific steps to reproduce? I can't tell what you are measuring and what your configuration is nor what the simplest configuration I can set up to see this is. How many nodes, how many DCs? > 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)
