Alex - I suspect you may be looking at some older documentation. AFAIK all HTTP functionality is now (Riak 2.0) supported via PBC so you can pick either transport or the other for all of your communication. In the past there was some functionality available only via HTTP. There are now some direct queries to the Solr API which are available only via HTTP, but that’s outside of Riak’s core [1].
I’m sure those more in the know will correct me if I’ve misspoken.

I can see how to do it now: bucket = client.bucket_type('counter_bucket').bucket('counters') Will be checking it more to see what can I do that is not yet documented. The Python documentation says at one point: "Some requests are only valid over 'http', and will always be sent via those transports, regardless of which protocol is preferred.". Can I know which requests are HTTP only? is it for something in particular? or they will be made into PBC at some point?

I know it's annoying because it's just raw Markdown at the moment, but this will be deployed to our normal docs site soon. Hope that helps!

So mainly the contents to store (json or not json) is not PB encoded semantically, but is encoded as a "body" field in the Message. That's good though. Another question... is there any estimated date for Riak 2.0 to be released? I'm playing with 2.0 beta 1 and the "list" object is a must-have for me (same as the "counter" object that can be found in Riak 1.4). Is crucial for me to decide which technologies to use in my new project; so far Riak 2.0 seems a great option, but I can not build under a beta. Another question now that I talk about "counters"... how do you do it with Python's PBC? I can see the functions: RiakClient.get_counter() and RiakClient.update_counter()... but... how do you create a new counter? how do you specify the special connotations to the bucket?

The protocol buffers are only used on the wire to encode Riak's protocol. If you want to use your own protobuffs messages, I suggest two things: 1. Decide on a `content_type` property for each of your data types and be sure to assign that to each key as you create it. I've used 'application/pb-person' as an example below. 2. Register encoder and decoder functions [1] on the RiakClient object, like so: client.set_decoder('application/pb-person', Person.ParseFromString) client.set_encoder('application/pb-person', lambda x: x.SerializeToString()) [1] http://riak-python-client.readthedocs.org/en/latest/client.html#serialization Cheers, On Mon, Jun 23, 2014 at 9:19 AM, Alex De la rosa <[email protected]> wrote: Hi there, I just installed RIAK 2.0 beta 1 and was playing with the Python library using 'pbc' (Protocol Buffers). test.py --------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+-------- import riak client = riak.RiakClient(host ='127.0.0.1', http_port = 8098, pb_port = 8087, protocol = 'pbc') bucket = client.bucket('people') key = bucket.new('alex', data={"username":"Alex","age":33}) key.store() print bucket.get('alex').encoded_data --------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+-------- it works perfectly and it prints {"username": "Alex", "age": 33} as it should print.

I'm a bit confused at the moment as it changed the way I normally would use Protocol Buffers.
