Hi guys,
This is mnesia operation in the following:
mnesia:dirty_match_object({comments,{Node, ItemId, '_'},
'_'}).
Now, I want to get it from riak.
For example:The KEY is {node, itemid, comment1} and {node,itemid,
comment2}.
I want to get comment1 and c
Sorry for top posting you, but I run a riak cluster behind two separate virtual IPs on my load balancer (an F5 LTM), one on a private IP that I write to and one on a public IP that can be read from. I control that behavior with iRules, though I'm sure other LBs have their own mechanism for the same
Hi all,
As the mid-July release of Riak looms large, the Basho team has been
discussing our continued support of the Innostore backend. Embedded
InnoDB was long ago abandoned by Oracle. We have not been actively
working on it either.
We believe that alternative designs (like LevelDB) are the futu
Hi Basho,
We have a running cluster of 5 nodes which accidentally was configured with
a default setting
"{ ring_creation_size: 64 }".
As suggested in documentation we cannot scale this cluster more than 6
machines,
so the only option is to migrate to a new cluster with a
larger ring_creation_size
Great, thanks!
Kaspar

Hi,
For testing purposes it would be awesome if Riak supported indexes in the
in-memory backend, are there any plans to implement this at some point?
Thanks,

Hi,
The high-level API in the Java client library (IRiakClient) does not allow
one to use byte[] arrays as keys, only Strings, whereas the underlying PBC
and http APIs (e.g. com.basho.riak.pbc.RiakClient) do, via the
fetch(ByteString, ...) methods. Any reason for this? Is it planned to add

^^ The Basho one is the correct one. Russel Brown (the repo owner below) works
for Basho and most likely just had a private fork for his work.

Hi,
I have found two Java libraries so far, and I'm not sure what their
connection is or which one I'm supposed to use:
https://github.com/basho/riak-java-client
https://github.com/russelldb/riak-java-client (last commit August 2011, so
probably outdated?)
Any hints?
Kaspar
My client is multi threaded. Instead of haproxy I had ELB in from of my

I used ephemeral storage without any improvement.
Also iotop and iostat did not show any saturation.
After talking with Sean Cribbs on IRC, I tried disabling nagle in riak
config, changed IO scheduler to noop, decreased cache size to 1 MB from 372
MB, removed load balancer.
After doing all this

Not being familiar with basho bench, these might seem like stupid
questions, but here goes:
What are the sizes of the operations that you're performing?
How have you configured your EBS storage?
A single EBS volume can only perform about 100 I/O operations per second,
give or take. A single host

What does your basho_bench config file look like?
Seeing a low number of ops/sec is usually an indicator that you're
hitting a bottleneck on the I/O path -- typically due to random reads.
LevelDB has a number of characteristics that can make this worse --
what happens if you use bitcask?

Hello,
Here is my setup of Riak 1.1.4
- 5 Nodes
- ami-a29943cb (EC2 AMI)
- m1.large (7.5GB Ram, 4 EC2 compute instances)
- EBS storage
- LevelDB backend
- Python Client with Protobuf (on a separate machine)
While loading data I am getting around 50 ops/sec.

Scale out - zerg rush your data.
Many smaller systems means that, in theory, you're going to be affected
less by poor performance of any single instance.
When you're building out instances in EC2 always remember that the largest
instance in a class of instances is most likely to be the only VM on

Hi, Venkatesh. As you have noticed, Riak does not support
partial-update operations.
