Maxim Muzafarov commented on CASSANDRA-16360: --------------------------------------------- [~samt], [~benedict] Since we've finished with the CASSANDRA-18255 and dropped the jdk8 support, so I think there is nothing stopping us from continuing to work on this issue, right? It has been quite a while since the last message, so I wonder if there are any new details that have come up since the last message. If so, please, share. I have perused the above discussion and Alexei's plan and it makes sense to me to proceed with preparing the patch. > 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 > Priority: Normal > Labels: protocolv6 > Fix For: 5.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). -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
