Firstly, thanks to everyone who attended yesterday’s MapReducing Big Data With Luwak Webinar. Here’s the recorded screencast of the webinar along with several other MapReduce and Luwak resources.
Basho Senior Engineer Bryan Fink has been doing some exceptional work with MapReduce and Luwak, Riak’s large-object storage interface. Recently, he wrote up two extensive blog posts on the specifics of Luwak and the powerful tool it makes when combined with Riak’s MapReduce engine.
Many thanks to commenter Mike for taking up the challenge I offered in my last post. The flaw I was referring to was, indeed, the possibility that Luwak would split one of my records across two blocks.
A few days ago, I announced a tool that I assembled last weekend, called luwak_mr. That tool extends Riak’s map/reduce functionality to Luwak files.
