[jira] [Commented] (CASSANDRA-6737) A batch statements on a single partition should not create a new CF object for each update

    [ https://issues.apache.org/jira/browse/CASSANDRA-6737?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13905931#comment-13905931 ]

-------------------------------------------

> BatchStatement creates a new ColumnFamily object (as well as a new RowMutation object) for every update in the batch, even if all those update are actually on the same partition. This is particularly inefficient when bulkloading data into a single partition (which is not all that uncommon).
