Subject [jira] [Created] (GORA-167) Make Cassandra keyspace consistency configurable within gora.properties
Date Tue, 28 Aug 2012 14:58:07 GMT
Lewis John McGibbney created GORA-167:
-----------------------------------------

             Summary: Make Cassandra keyspace consistency configurable within gora.properties
                 Key: GORA-167
                 URL: https://issues.apache.org/jira/browse/GORA-167
             Project: Apache Gora
          Issue Type: Improvement
          Components: storage-cassandra
    Affects Versions: 0.2.1
            Reporter: Lewis John McGibbney
            Assignee: Lewis John McGibbney
            Priority: Minor
             Fix For: 0.3


Current in CassandraClient#checkKeyspace() consistency is hard coded such that consistency
level is .ONE which permits consistency to wait until one replica has responded. This could
be improved to enable users to specify other consistency profiles e.g. 


        ANY: Wait until some replica has responded.
        ONE: Wait until one replica has responded.
        TWO: Wait until two replicas have responded.
        THREE: Wait until three replicas have responded.
        LOCAL_QUORUM: Wait for quorum on the datacenter the connection was stablished.
        EACH_QUORUM: Wait for quorum on each datacenter.
        QUORUM: Wait for a quorum of replicas (no matter which datacenter).
        ALL: Blocks for all the replicas before returning to the client.

Configuration should be made available through gora.properties
