Stefania created CASSANDRA-12919: ------------------------------------ Summary: Fix inconsistencies in cassandra-stress load balancing policy Key: CASSANDRA-12919 URL: https://issues.apache.org/jira/browse/CASSANDRA-12919 Project: Cassandra Issue Type: Bug Components: Tools Reporter: Stefania Assignee: Stefania Priority: Minor Fix For: 3.0.x, 3.x
The default load balancing policy in cassandra-stress is null, which means that the driver will currently wrap {{DCAwareRoundRobinPolicy}} with {{TokenAwarePolicy}}. However, when a white list of nodes or a data center are specified in the command line options, then either {{WhiteListPolicy}} or {{DCAwareRoundRobinPolicy}} are used respectively, without wrapping them in a TokenAwarePolicy. This means that in the default case token aware routing is applied, but in some cases it is not. Token aware routing could give a performance boost of up to 2.5 times on bare metal, making comparisons of workloads problematic. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
