2013-08-04 Thread Massimiliano Ciancio
Hi all, I'm new to Riak and I'm evaluating its use in a project in which I've to map some many-to-many relationship with millions of link. That is, imagine you have objects of type X={x_0,x_1,...,x_n} and objects of type Y={y_0,y_1,...,y_m} that are related. Xs are connected to millions of Ys and v

Riak 2.0 Sets

2013-12-16 Thread Massimiliano Ciancio
Hi all, I've two questions about new Riak 2.0 sets: 1) how many elements can be added to a set? Are 1-10-100 millions of keys, about 20-30 chars each, reasonable for a single set? 2) is it possible to do union/intersection/diffs with a riak set? Any update about 2.0 availability? Thanks MC ___

1.4 or 2.0?

2014-02-15 Thread Massimiliano Ciancio
Hi all, I've a big question... if you have to go in production in the next two months (about at the half/end of April) you use Riak 1.4 or 2.0 pre-x ??? How hard will it be to upgrade from 1.4 to 2.0? At the moment I don't need new features (crdt) of 2.0 version. Maybe only new simpler configuratio
