Subject [jira] [Created] (CASSANDRA-6890) Remove mmap'ed i/o from read path
Date Wed, 19 Mar 2014 20:45:43 GMT
Joshua McKenzie created CASSANDRA-6890:

             Summary: Remove mmap'ed i/o from read path
                 Key: CASSANDRA-6890
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Joshua McKenzie
            Assignee: Joshua McKenzie
            Priority: Minor
             Fix For: 3.0

Since we actively unmap unreferenced SSTR's and also copy data out of those readers on the
read path, the current memory mapped i/o is a lot of complexity for very little payoff.  Clean
out the mmapp'ed i/o on the read path.
