[jira] [Created] (CASSANDRA-8615) Create -D flag to disable speculative retry by default

J.B. Langston created CASSANDRA-8615:
----------------------------------------

             Summary: Create -D flag to disable speculative retry by default
                 Key: CASSANDRA-8615
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8615
             Project: Cassandra
          Issue Type: Improvement
            Reporter: J.B. Langston


Some clusters have shown increased latency with speculative retry enabled.  Speculative retry is enabled by default when upgrading from 1.2 to 2.0, and for large clusters it can take a long time to complete a rolling upgrade, during which time speculative retry will be enabled. Therefore it would be helpful to have a -D flag that will disable it by default during an upgrade.
