Hi everbody,
I'm using riak to store large numbers of FX rates, to allow for deep
backtests of trading strategies. My code seems to be working, except
that I don't get any keys back from 2i range requests.
Here's the code which puts the rate into riak (the rate is itself a

A single node deployment of the memory backend will certainly work,
but will not be as performant as Redis.
Here are some suggestions for running the memory backend in production:
1. Since you are running a single node cluster, set your n_val to 1 [1]
2. Make sure you set the max_memory parameter
Follow the white rabbit:

Sounds like zdbbl.. I'm running 1.3.1 but it started after added 6 more
nodes to the previously 12 node cluster. So maybe it is because of a 18
node cluster?
I'll try the zdbbl stuff. Any other hint would be cool (if the new
kernel parameters are also good for 1.3.1.. could you provide them?).

Btw, another alternative is to use the leveldb memory-backend impl

Since Redis was designed with that use more in mind, I would guess a single
node of Redis would be faster than a single node of RIak with N=1. If you
still want to run Riak, you'd want to lower the ring size to maybe 8 so you
weren't running 64 vnodes on a single node. This would obviousl

Yes, it has similar rules. Nested objects have their fields joined by '_'.
Arrays become repetitive field names, which should map to a multi-valued
field. You can use the URL I provided in the last response to see exactly
how field-values are extracted.

Does the JSON extractor work in a similar fashion, or does it follow its

Forgot to mention, with N=2 should he be able to have only 4 nodes and

I know is not recommended but shouldn't N=2 reduce the minimum

Since the data he is requiring to store is only "transient", would it
make sense to set N=2 for performance? Or will N=2 have the opposite
effect due to amount of nodes having such replica?

Is it possible to add a node to cluster only for enabling riak control and

As Eric said, the XML extractor causes the nested elements to become
