Hi all,
I am running couple of months cluster of 5 Riak nodes on CentOs (Bitcask
backend).
Till today everything was fine, but today one of the nodes just stopped to
work.
When trying riak start/stop/ ... it just claims that node doesn't respond

Restart of server didn't help. What should
I did some tests and saw that it is correct only for very recent keys.
The DB becomes consistent for specific key very fast (few seconds) at
least for 5 nodes in 1Gbit network (which seems to be enough or almost
enough
for required capacity and throughput with bitcask backend).

Thanks a lot.

Hi all,
We are using Riak mainly as key-value storage for fast store/get
operations. However we would like
to use some of its search functionality. We need to run offline search
operations on some fields of
our JSON values. Our storage back end is bitcask cause it is better in
terms of
latency/thr

Hi all,
I have Riak cluster consisting of 5 nodes that contains about 30 millions
of keys (35% of capacity according to Riak Control).
Currently we have single JAVA client reading and writing records to same
node. I need some tips, how to use the client efficiently
to reach maximal throughput - I

Hi all experts,
I want to use Riak for caching and have few questions:
1) How faster is using memory back-end over bitcask back-end (on SSD)?
2) If throughput satisfying, is there any reason to use more than two nodes?
3) When my memory reaches preset limit (lets say 4Gb) what is going to
happen

Hi all,
Is there any multiget functionality in Riak (like in memcached)?

Hey fellows,
I have few questions:
1) I know that minimal recommended size of Cluster is 5 nodes.
However I have at this point only two servers.
a) Would the data be replicated among those two servers. If one node is
down,
would other node cover whole DB?
b) When I add new 3

Probably I don't get something.
Address: https://127.0.0.1:8069/admin assuming browsing on localhost.
However Riak is running on Linux server without Gnome/KDE.

Hi fellows,
I have cluster of 2 physical Riak nodes (I know it is not enough) running
on CentOS 6.
Now I am trying to configure Riak control - did everything according to
instructions:
1) Enabled HTTPS in app.config
* {https, [{"0.0.0.0", 8069 }]} *
*
*
2) Generated SSL certificate using this
