Paulo Motta commented on CASSANDRA-17768: ----------------------------------------- I think the original problem CASSANDRA-11841 was intended to solve is when operators are using networks/firewalls they have little/no control of (ie. cloud/vpn providers), and can't set recommended net.ipv4.tcp_keepalive* settings. The idea is to have an app-layer keep-alive to ensure we don't depend on network settings to keep long-lived cross-datacenter connections alive. This is certainly a niche feature, but I don't know if it's still useful or not. A few pointers to conextualize the use-case being addressed by that setting: - CASSANDRA-12830 - [https://www.mail-archive.com/user@cassandra.apache.org/msg54529.html] - [https://docs.datastax.com/en/archived/cassandra/2.0/cassandra/troubleshooting/trblshootIdleFirewall.html] > streaming_keep_alive_period is not used after [CASSANDRA-16927] CEP-10 Phase > 1: Refactor Streaming > -------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-17768 > URL: https://issues.apache.org/jira/browse/CASSANDRA-17768 > Project: Cassandra > Issue Type: Bug > Components: Legacy/Streaming and Messaging > Reporter: Ekaterina Dimitrova > Assignee: Aleksey Yeschenko > Priority: Normal > Fix For: 4.1-beta, 4.1.x, 4.x > > > While working on another ticket I noticed that after [CASSANDRA-16927] CEP-10 > Phase 1: Refactor Streaming > streaming_keep_alive_period is not used anymore, except to print it in error > message > [here|https://github.com/apache/cassandra/blob/cassandra-4.1/src/java/org/apache/cassandra/streaming/StreamSession.java#L689] > If the property should not be used anymore, we need to deprecate it and fix > the error message as it is misleading. > [~benedict] , [~samt] , [~aleksey] , can you, please, check and take care of > this one as authors of that patch? > Thank you in advance! -- 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
