Subject [jira] [Created] (DRILL-1525) Use XXHash algorithm for hash functions
Date Fri, 10 Oct 2014 20:20:34 GMT
Mehant Baid created DRILL-1525:
----------------------------------

             Summary: Use XXHash algorithm for hash functions
                 Key: DRILL-1525
                 URL: https://issues.apache.org/jira/browse/DRILL-1525
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Mehant Baid
             Fix For: 0.7.0


Currently we are using murmur hash algorithm for performing hash operations. We would like
to move to XXHash which is a fast non-cryptographic  hash algorithm. More information can
be found here: https://code.google.com/p/xxhash/

The implementation should also eliminates an extra copy of the ByteBuf to be consumed by the
hash function.
