Subject [jira] [Commented] (CASSANDRA-11488) Bug or not?: coordinator using SimpleSnitch may query other nodes for copies of local data
Date Wed, 06 Apr 2016 15:48:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15228500#comment-15228500
] 

Sylvain Lebresne commented on CASSANDRA-11488:
----------------------------------------------

bq. I think it's important to consider it

Consider what? As I said, dynamic snitch is the default which means that the snitch is pretty
much only used for determining the DC and rack of the nodes.

> As [~Stefania] explains [in this JIRA comment|https://issues.apache.org/jira/browse/CASSANDRA-11225?focusedCommentId=15221059&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15221059],
{{SimpleSnitch}} does not implement {{IEndpointSnitch.sortByProximity(localhost, liveendpoints)}},
so a query for data on the coordinator may query other nodes. That seems like unnecessary
work to me, and on that note, Stefania woonders [in this JIRA comment|https://issues.apache.org/jira/browse/CASSANDRA-11225?focusedCommentId=15223598&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15223598]
- should this be considered a bug?
> Stefania, I'm assigning you here -- could you find the right people to involve in this
discussion?
