[jira] [Created] (CASSANDRA-6569) Batchlog replays copy the entire batchlog table into the heap

Rick Branson created CASSANDRA-6569:
---------------------------------------

             Summary: Batchlog replays copy the entire batchlog table into the heap
                 Key: CASSANDRA-6569
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6569
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Rick Branson
            Assignee: Aleksey Yeschenko


The current batchlog replay path will read the entire batchlog table into the heap. This is pretty bad. This was compounded by CASSANDRA-5762, which caused the SELECT statement used by the batchlog replay to bring the entire row into memory instead of just the selected columns.
