Link-Walking + Replication Factor
Hi, I've been experimenting with Riak and I've run into unexpected behavior when using link-walk. Basically link-walking stops working for a bucket that is set with replication factor of 1. The replication factor was always set before using the bucket (filling it with data), both on a per-bucket basis and on a global basis (on app.config) and the result is the same. I'm running Riak 0.14.1 on Mac OS X and I'm using Ruby's client. It's not a client problem though since the same problem exists when I issue the link-walk directly through the http interface (using curl). It's possible that this behavior is expected but I couldn't find anything on it, so spare me my ignorance ;-) Regards, André Silva ___ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
Re: Link-Walking + Replication Factor
Hi André, You are correct; there is an issue with link walking when N=1. Bug #975 has been filed to address this issue: https://issues.basho.com/show_bug.cgi?id=975 Thanks, Dan Daniel Reverri Developer Advocate Basho Technologies, Inc. d...@basho.com On Fri, May 20, 2011 at 4:12 AM, André Silva wrote: > Hi, > > I've been experimenting with Riak and I've run into unexpected behavior > when using link-walk. > Basically link-walking stops working for a bucket that is set with > replication factor of 1.

Riak Recap for May 18 - 19
Afternoon, Evening, Morning to All - For today's Recap: some great content from #riak, an upcoming Riak talk in Chicago and more. Enjoy and have a great weekend. Mark Community Manager Basho Technologies wiki.basho.com twitter.com/pharkmillups Riak Recap for May 18 - 19 = 1) We merged a great contribution into Riak Search from gpascale et al. * Details are in this commit here ---> https://github.com/basho/riak_search/pull/56 Thanks! Keep the code coming. 2) Q --- Before I go an write one from scratch, I figured I should ask: Does anyone have a script/Erlang snippet for discarding and completely rebuilding a Riak Search index? (from joell via #riak) Anyone have anything to share? I would love to get something like this in contrib.basho.com if it exists... 3) dambalah, aphyr and Vaganond had a quick chat in #riak that started with, "Is riak susceptible to some kind of 'injection attack'? If so, what's an example and what do application developers need to do to prevent these?" Read here ---> https://gist.github.com/983702 4) Q --- Lets say I have several new nodes to add, is the recommended procedure to add them one at a time and wait for all transfers to finish, or can you actually add several? A --- The current recommended procedure is to add one node at a time and wait for the partition transfers to finish before proceeding to the next node addition. Specifically: * Use the "riak-admin join" command to kick off the cluster expansion * Run "riak-admin transfers" periodically to keep an eye on the nodes awaiting or passing off partitions (this may take a bit to complete); an alternate (and less expensive) way to keep an eye on on this is to just watch the logs. * When "riak-admin ringready" prints "TRUE ..." to let you know that all nodes agree on the ring state, you're good to go. See http://wiki.basho.com/Command-Line-Tools.html for all the command line tools. (It's worth nothing that making this process smoother and more fluid is high on our list of priorities.) 5) It looks like Susan Potter (@susanpotter) will be giving a talk about Riak and Link Walking at the WindyCityDB in Chicago at the end of June. * Details here ---> http://windycitydb.org/sessions/#potter Anyone else planning to be at this event? 6) Version 0.1501 of Linkfluence's Perl Client was just released. * Details here ---> https://twitter.com/#!/cpan_new/status/71176812394328064 ___ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
