"Bucket type" is shared metadata across a set of buckets. That metadata needn't necessarily define a datatype. In fact, there are many cases where you might not. For example, you would use a bucket type for strong consistency, or associating a search index with many buckets.
In other words: bucket type == higher-level bucket namespace (http://docs.basho.com/riak/2.0.0/dev/advanced/bucket-types/) datatype == a description of how a stored object's type, like a map/set/counter (http://docs.basho.com/riak/2.0.0/dev/using/data-types/) Hope that helps, Eric On Aug 17, 2014, at 11:12 AM, Alex De la rosa <alex.rosa....@gmail.com> wrote: > Hi Eric! > > Thank you very much! this certainly solved it! :) however, I have to say that > is very non intuitive as "bucket_type" would look like the data type > (counter, set, map) and the "bucket" part the name of the bucket you > created... so it looks as it should work exactly the contrary as how it has > to be done (><). > > However, is finally fixed and I can finally use counters! thank you so much. > > Thanks! > Alex > > > On Sun, Aug 17, 2014 at 8:04 PM, Eric Redmond <eredm...@basho.com> wrote: > Alex, > > looking through your previous emails, it looked like you created a bucket > type named "likes".
