------------------------------------------
Summary: Remove mmap'ed i/o from read path
Key: CASSANDRA-6890
URL: https://issues.apache.org/jira/browse/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.
