Subject [jira] Commented: (CASSANDRA-197) Expose ring map to client for more direct access
Date Sat, 22 Aug 2009 22:57:14 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12746517#action_12746517
] 

Jeff Hodges commented on CASSANDRA-197:
---------------------------------------

I'm assuming then that the type of the return value of get_string_property (or get_string_list_property)
would change to accommodate a map instead of a simple string? Or am I missing something?

> For certain applications, it would be nice if a read is sent to a node that owns the
data locally. This saves an extra network hop. To do that, a client will need to cache the
ring map and use it to figure out the nodes owning a row.
