Thanks Alex,
I'm thinking I might just have to start with 16 nodes just to reduce the
number of vnodes i.e. with a partition size of 1024 and then scale up to 64
nodes. Not sure what I'm going to do when I move away from Cloud Servers where

A few billion? Pssh. You know what's cool? A Trillion.

heffergm,
Would it be possible to get a peek at your logs -- the information you
provided is insufficient to make any conclusive determination.
Thanks,

Copying the list back in, just in case someone smart has a response ;)

Riak Recap for February 17 - 22

I'm trying to figure out whether there's an easy way to accomplish
something like a "recursive/looping map-reduce query" in Riak.
A use case for this is when the objects in the database form a linked
list, tree, or graph of some kind, and you want to look up a set of
objects whose depth from the i

No, nothing similar in our case. No crashes either for that matter, although
non-functional MR is just as bad.

I also discovered MR issues during a rolling upgrade to 1.1.0 last
night. We had so many MR errors that the 1.1 node crashed altogether,
and I had to roll it back to 1.0.3. Basho support is working on that
problem.

After upgrading to 1.1, we've had all kinds of MR issues (essentially all
failing). I'm seeing tons of these in the logs. Any ideas? We've rolled back

Thanks *Russel* for a very clear and detailed explanation.
Also I would like to know if it is possible to query on 2 or more indices
in a single indexQuery ?

I am running following IndexQuery :
IntIndex intIndex=IntIndex.named("points");
IndexQuery iQuery = new IntRangeQuery(intIndex,"fkUsers",1100,1300);
MapReduceResult
resultInt=client.mapReduce(iQuery).addReducePhase(NamedErlangFunction.REDUCE_IDENTITY).execute();

Thank you Jeff! Will try that tomorrow at work.

Hi all,
We're seeing a new timeout error after upgrading our cluster to Riak
1.1. The error message:
{"phase":0,"error":"[timeout]","input":"{{<<\"service_profiles\">>,<<\"8fh/2\">>},{struct,[{<<\"key\">>,<<\"s-10925\">>}]}}","type":"forward_preflist","stack":"[]"}
Sean indicates that the "forwa
Rohman,
You'll also need to enable HTTPS (and SSL) in the riak_core section of the
app.config file. Also, don't forget to change the port used for HTTPS to
something different (I personally use 8069).
Note the required changes to the app.config file in the README:

Thanks Jon and congratulations for the new release,
We will be available to fill any missing info and iterate on this. I the
meantime we will be progressing in the port to the new version, so that we get
a more precise idea of the implications.
Cheers,

Hi Rajat,
I would construct two secondary indexes (2i) when Post objects are created in
the form of
* userid_timestampOfPost
* timestampOfPost
This gives you the ability to do a range query for posts created by a specific
user and a general range query to posts by all users made within
Considering I have Buckets for Users and Posts and I want to get users
postsin last
24 hours, how should I go about it.
Post's json data has a key postTime. How to filter search based on value's
key value ?
