[jira] [Created] (CASSANDRA-17109) CEP-15: (Accord) Transactions must be sent to an optimal number of replicas

Benedict Elliott Smith created CASSANDRA-17109:
--------------------------------------------------

             Summary: CEP-15: (Accord) Transactions must be sent to an optimal number of replicas
                 Key: CASSANDRA-17109
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17109
             Project: Cassandra
          Issue Type: Sub-task
          Components: Accord
            Reporter: Benedict Elliott Smith


Today Accord sends the complete transaction to every shard. This is unnecessary, Accord should instead nominate a single primary shard to replicate the transaction, with the other shards receiving only the {{(txnId,primary shard key)}} tuple as part of PreAccept.
