Subject [jira] [Created] (CASSANDRA-8709) Convert SequentialWriter from using RandomAccessFile to nio channel
Date Fri, 30 Jan 2015 17:59:34 GMT
Joshua McKenzie created CASSANDRA-8709:
------------------------------------------

             Summary: Convert SequentialWriter from using RandomAccessFile to nio channel
                 Key: CASSANDRA-8709
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8709
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Joshua McKenzie
            Assignee: Joshua McKenzie
             Fix For: 3.0


For non-mmap'ed I/O on Windows, using nio channels will give us substantially more flexibility
w/regards to renaming and moving files around while writing them.  This change in conjunction
with CASSANDRA-4050 should allow us to remove the Windows bypass code in SSTableRewriter for
non-memory-mapped I/O.

In general, migrating from instances of RandomAccessFile to nio channels will help make Windows
and linux behavior more consistent.
