Adrien Grand commented on CASSANDRA-5862: ----------------------------------------- bq. What is the gain from switching to xxHash ? [...] Specifically, I'm interested in hash diversity. xxHash happens to pass all tests of the SMHasher test suite (http://code.google.com/p/smhasher/wiki/SMHasher, see scores and speed of some common hash function at http://code.google.com/p/xxhash/) which has many tests including hash diversity. > Switch to adler checksum for sstables > ------------------------------------- > > Key: CASSANDRA-5862 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5862 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Jonathan Ellis > Assignee: T Jake Luciani > Fix For: 2.0.1 > > Attachments: 5862.txt > > > Adler is significantly faster than CRC32: > http://java-performance.info/java-crc32-and-adler32/ > (Adler is weaker for short inputs, so we should leave the commitlog alone, as > it checksums each mutation individually.) -- This message is automatically generated by JIRA.
