Subject [jira] Created: (CASSANDRA-2235) Counter AES performance issue
Date Thu, 24 Feb 2011 08:09:38 GMT
Counter AES performance issue
-----------------------------

                 Key: CASSANDRA-2235
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2235
             Project: Cassandra
          Issue Type: Bug
            Reporter: Chris Goffinet
            Assignee: Chris Goffinet
             Fix For: 0.8


We noticed tonight when trying out AES for Counters in trunk, there is a serious performance
issue when inlining the SSTables. We found that the way we are seeking in the file, BRAF keeps
flushing out its buffer of 8MB, and we call dfile.sync() on every row. We are finalizing a
patch to write a new SSTable on rebuild, instead of inlining.
