-------------------------------------
Summary: Add JDK9 new CRC32C checksum
Key: CASSANDRA-13908
URL: https://issues.apache.org/jira/browse/CASSANDRA-13908
Project: Cassandra
Issue Type: Improvement
Components: Local Write-Read Paths
Reporter: Yingqi Lu
Dear All,
JDK9 introduces a new API java.util.zip.CRC32C. It has an optimized
implementation using IA crc32c instruction. Our early data show CRC32C provides
additional performance benefits over CRC32 checksum.
We are proposing to add CRC32C as one of the checksum types in addition to
Adler32 and CRC32. Performance data and prototype code changes will be
submitted here soon. At the meantime, please feel free to provide your feedback
and comments.
Thanks,
Yingqi Lu
