Afternoon, Evening, Morning to All, For today's Recap: new MapReduce code for Luwak, a new C driver, the birth of "bashobot", and some questions from #riak.
Enjoy, Mark Community Manager Basho Technologies wiki.basho.com twitter.com/pharkmillups ---- Riak Recap for Jan. 14 - 16 1) seancribbs and ossarah had a very brief chat in #riak that started with "Is there some way, in a map phase, to fetch the object that a link refers to?" * Gist here ---> https://gist.github.com/783629 2) Piotr Nosek has started work on another C Driver for Riak. * Code on GitHub here ---> https://github.com/fenek/riak-c-driver * Added to the wiki here - http://wiki.basho.com/Community-Developed-Libraries-and-Projects.html#Client-Libraries-and-Frameworks Thanks, Piotr, for both the code and the wiki updating. 3) There is all sorts of good stuff happening with Luwak and MapReduce. * Basho Hacker Bryan Fink put together something called "luwak_mr" which will be a much-appreciated piece of code for anyone who is trying to run MapReduce jobs over data in Luwak. Repo here ---> https://github.com/beerriot/luwak_mr * He also added a function to Riak Function Contrib for doing MapReduce over your Luwak data. Function here ---> http://contrib.basho.com/luwak_mr.html *For those of you who aren't familiar with Luwak, see: https://github.com/basho/luwak and http://wiki.basho.com/Luwak.html 4) Q --- Does riak support ttl expiration of objects? (from heckacopter via #riak) A --- Yes. See "riak_kv_cache_backend" towards the bottom of http://wiki.basho.com/Configuration-Files.html#app.config 5) Q --- Is it possible to implement transitive closures by link walking? (from cirwin via #riak) A --- Hard to give a definite "no" without knowing exactly what you're trying to do. However, if you're trying to compute reachability between arbitrary objects in constant time using link walking, then you'll probably want a more specialized graph database. Links weren't made to handle these type of algorithms. 6) We have a new bot in #riak. Sean Cribbs wrote and released bashobot - https://github.com/basho/bashobot/ - and it's now up and running in #riak. Hop into the #riak IRC room on irc.freenode.net and type "!help" to see it in action or check out the repo's README for a complete list of commands. 7) Justin Sheehy answered a question on Quora about the nature of buckets in Riak.
