--------------------------------------
Summary: CRC32 is inefficient on x86
Key: CASSANDRA-16360
URL: https://issues.apache.org/jira/browse/CASSANDRA-16360
Project: Cassandra
Issue Type: Improvement
Components: Messaging/Client
Reporter: Avi Kivity
The client/server protocol specifies CRC24 and CRC32 as the checksum algorithm
(cql_protocol_V5_framing.asc). Those however are expensive to compute; this
affects both the client and the server.
A better checksum algorithm is CRC32C, which has hardware support on x86 (as
well as other modern architectures).
