A lovely "good morning" to you, too. > as part of my evaluation of Riak, I am looking at the M/R capabilities and I have several questions: 1/ the doc states that " Riak MapReduce is intended for batch processing, not real-time querying." But as of now, you always get the results and cannot automatically store them in a bucket like you would do with MongoDB for example. Is taht something that is on the roadmap? > This isn't something that's on the roadmap. That doesn't mean we won't do it, but no one is working on code that does this at the moment. That said, I'm told by one of our smart, busy minds here that works on m/r that it would not be the most complicated addition. It may well end up being part of future work but, again, there's no timeline on it. In the mean time, any use case details you could share (short of "like you would do with MongoDB") that would help inform the development would be stellar. If you were feeling adventurous and wanted to write some erlang code, this behavior could be written as part of map or reduce job. > 2/ Basho blog has two articles from last year on Hadoop on top of Riak. Is this project still live? It is on github, so I can always dig it up and work on it, but I am wondering if there is something like Yokozuna for Hadoop integration. > The work on this specific code has stalled. That said, there are some people using Riak in production alongside hadoop, and we have plans to build deeper integration between the two at some point. As an aside, if you're looking for lower latency responses on implementation questions, you might want to consider hanging out in #riak on freenode.
