Sam Tunnicliffe updated CASSANDRA-16360:
----------------------------------------
Impacts: Clients (was: None)
> 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
> Assignee: Alexey Zotov
> Priority: Normal
> Labels: protocolv6
> Fix For: 4.0.x
>
>
> 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).
