Hi,
I am looking for documentation that describes how something like
matrix multiplication can be done using Riak MR using Java. This is to try
some algorithms for mining big pagerank matrices but
with smaller examples. Is this usecase applicable for Riak ?
I plan to install Riak on my lapt

Indexes have some overhead of their own, but they also have a reasonable limit
on doc count (hundreds of millions per node). To answer you question requires a
bit more knowledge of your use-case. One index can be more efficient, as long
as you're not creating hundreds of thousands of b
Hi Eric,
I think I will be running with a 10-30 thousands buckets, with some of them
almost empty (<10 keys) but some with hundreds of thousands of keys.
I'm pretty sure I can stay away from hundreds of millions docs per node
limit. Does it mean that I can simply grow my Riak cluster to split the
You can check if your object has siblings by performing a key get, and see if
two values return. If not, then it may be the index. Can you paste the response
where you get two values?
Thanks,

Go ahead and submit an issue. We'll take a look at it, but it could be months
before a fix ends up in a release. I'd take Ryan's suggestion for now and
replace spaces with another char like underscore (_).

Thanks,
Unfortunately I have few millions of keys in a live application and its
almost impossible to update them all without stopping the service. And it
can't be as simple as whitespace<->underscore replacement (what if there
will be a real underscore in the name?).

Hey Eric.
Awesome! Thanks so much for the feedback. I really appreciate the help.
I guess I'll have to test each method on our infrastructure to really know for
myself.
Cheers,
