Can someone explain the difference between the get_update_metadata and
get_metadata functions in the Erlang PB Client for Riak? It's very
confusing...
Thanks,
Andrew

The more fields the better. I like this change.

What do your config files look like? Do you have proper permissions on the
Riak directory?

Hello,
I'm wondering if anyone has explored the idea of using Zookeeper in front
of Riak to handle locking. My thought is that a client goes to Zookeeper
to get a lock on a key before updating. Any other client that wishes to
update the same key must check for the existence of a lock. If it ex

Bryan,
What version of Erlang? You should check this out:

I was curious if anyone has any thoughts on what is more performant, links
or key filters in terms of secondary links. For example:
I want to be able to look up a user by id and email:

Two buckets: user and user_email, where id is the key of user and email is

Yes, but this would be a bucket where each key would only ever have one link
pointing back to the original user.

I don't totally understand what you're doing in your code, but it looks like
you have the map phase before the link phase which doesn't make sense since
you want the data from the link phase passed on to the map phase, not the
other way around.

I'm curious if there has been any talk to drop the protocol buffers

which support more languages, like Bert (http://bert-rpc.org/) or

I'm thinking that maybe it's better to store documents just as the record

Hello,
I'm having issues link walking using the Map Reduce link function. I am
using HEAD from Git, so it's possible that's the issue, but here is what is
happening.
I've got two buckets, user and user_email where user_email contains a link
to the user.
When I run this:
{
"inputs": [
voke_anon_js,3},{riak_kv_js_vm,handle_call,3},{gen_server,handle_msg,5},{proc_lib,init_p_do_apply,3}]}
Offender:

And related, does Bitcask have any sort of compression built into it?

Has there been any talk of using compression, maybe something like
Snappy (http://code.google.com/p/snappy/) since it's fast and
shouldn't affect performance too much?

Nevermind on the lists:sort issue below as I realized that list:umerge
requires that the lists be sorted.

They should exist on each node (server-side). You set up the code
path using http://wiki.basho.com/Configuration-Files.html#add_paths or
-pz in vm.args for each node. Once you do that you (assuming Erlang),
you would just compile the file and put the beams in the directory you
stated in the path
So much better than the old API!! Thanks for the hard work on this.

It seems to me that you need to put weights on your requirements
because I think it's going to be pretty tough to meet all of them with
just one solution. For example, you can use something like Redis to
do fast writes, but it doesn't have Map-Reduce queries. So, you can

I just want to make sure I'm totally clear on this. Bob's solution
would work well with my design. So basically, this would be the

Hello,
I'm currently using the Riak Erlang client and when I do a get_index I
only get the keys back. So, my question is, is it better to get the
keys, loop through them and run a get on them one by one, or is it
better to write my own MapRed job which queries the index and then
runs a map phase

You should look into using HAProxy in front of your nodes. Let HAProxy
load balance between all your nodes and then if one goes down, HAProxy just
pulls it out of the load balancing cluster automatically until it is
