Hello Veronika -
We're actively working on the YCSB project located at [0]. It should work
fine with Riak 1.4. Since the existing implementation of YCSB is a
work-in-progress, you can't trust any results it gives you until we get it
merged upstream with the official YCSB repo. I'm not sure what's causing the
"Read timed Out" exception, can you provide any logs?
Cheers -Dave

Thank you for reply. Of course I can try new version but will I be able to run
YCSB for 1.3 over 1.4? This is my concern. What is the minimal RAM required for
Riak to work correctly? I mean, what I am doing is inserting 100.000 records at
once.

Subject: Re: Riak 1.3 YCSB Read Time Out
Hi Veronika,
Riak 1.4.0 was released yesterday, with the new streaming features
nodes will stream keys to you instead of working with the whole
result in memory, which will probably avoid the timeout.
Though your RAM and specially using a VM could be a limiting factor,
still worthy a try.
Once your node is up type riak-admin diag and see if some parameters
need to be adjusted.
For more information on tuning:

HTH,
Guido.

Greetings,
I am currently testing different NoSQL databases and now I
was starting Riak. I downloaded and installed Riak 1.3 and was
executing YCSB over it. But after some time (40 sec) of
loading data, I got "Read timed Out" exception.
How can I solve it? I am working locally, on same machine
so my connection is to localhost. Is that lack of RAM that
causing that? Since I am using VM and I only have 2GB RAM for
it. Or it is something else I can configure?
Regards, Veronika
