I know it's not good to use RIAK in VMs, but even so I would like to get
some support in one scenario:
We have a 4 node RIAK cluster, each one in different VMs. In case one of
the VMs goes down and needs to be restarted in a different machine (so it
won't have the same data as the node it's replac
D'oh. I meant 400 bytes.

Very interesting!
Regarding feature #1: I don't understand how an ets based index adds up to 400k
per posting; as your write up suggests. Did you mean 400b? I thought ets was
reasonably memory efficient. Do you use very large keys?

I've been experimenting with a port of my application from single-node
BerkeleyDB backend to Riak, with some promising results. Features #1 and #3
are excellent news, and will definitely result in increased performance.
Thanks for keeping us posted on your work,

So, actually, it turns out that's not exactly the command I typed. I
actually typed:
curl -v -XPUT -H "Content-Type: application/json" -d '{"terms": "",
segments: "d do doc docs"}' '

That is, I left out a pair of quotation marks, so my

I reproduced this at the command line. Here I'm storing two documents, with
IDs 'doc8' and 'doc9', into a search-enabled bucket named 'test-search'.
# This command works, even though 'lsh' is empty. I believe this is because
I've never put a field named 'lsh' in this bucket, 'test-search'.

Hi Bhuwan,
That error usually means that you are overloading your cluster in some
fashion.
To fix this you could try a rolling restart of your nodes.
To find the root cause though, can you reply with the following information:
What are the ulimit settings on your riak machines?
Are you running a
I'm seeing tons of errors in our log files and not sure what they mean

I think it might not be much of a problem to not repeat Maps... From this example on their site:
---from disco.core import Job, result_iterator
def map(line, params): for word in line.split(): yield word, 1
def reduce(iter, params):
Thank you! is pretty interesting, will have to try and see : )

What's interesting is that Pavlo Baron mentions a heavily modified Disco,
that he altered to make it run alongside each Riak node. I wonder if those
mods are available?
It would be great to talk to him about this.

Hi,
I've been following the Disco Project for a couple of years. The tricky part
with using Disco with Riak would be to make sure each map phase is not executed
multiple times over the same data*. Also, since each map phase would
(preferably) run on the same host as its data (for data locality)

Is written in Erlang ( the core app ) but the MR jobs are written in
Python... in the same way that Riak is written in Erlang but the MR jobs
are written in JavaScript ( also can be written in Erlang though )

Oh no, spoke to soon, it is 50% Erlang… I just happened to be looking at the

Hello everybody,
Has anyone tried to use Riak with Disco? [

RIAK-HADOOP connector project seems not going anywhere ) and I think
Disco is quite interesting, moreover is written in Erlang same as Riak.

Ok, we got it. We have made a fix that is working for us handling the
result.
Thanks for your time and responses around this!

Yes, but also include funs in Riak and could be enabled by
passing sending. To enable regex matching the args might contain a 'regex'
atom. Taking the my previous example you could match a timerange by
passing a term [{datetime, [{month, [8], {hour, [{8, 16}]}]}] which
translates to anything in aug
Olav,
Do you mean similar to passing a map function into M/R, but a function
which is applied to the term rather than the object? I agree that would be
neater, and much more powerful ... I just don't know how to do it.

Hi Christian,
Thanks for the reply!
That code snippet is very similar to what I had, except I was missing the
ack_keys call. That leads to the trivial question of why is there two keys
messages, {Id, From, {keys,Keys}} and {Id, {keys,Keys}}? I guess the ack

Hi guys,
Russell is correct. In CI we gather the responses as they come in, in
whichever order they're received. We make some effort to flatten the
result, but we take the approach of being "smart enough to get you the
results, but no smarter".
We don't do anything to reorder or manage the result

Thanks for your help. Your query returned the same number over and over
again just as expected.
I think I have found the reason for my problem though. The client lib
CorrugatedIron seems to wrap each document in the MapReduce result into a
array turning the result into a nested array looking like:
