Speed.  I'm running 6 nodes on EC2 with load balancing and instance storage.
I'm seeing an average of 115 ms per using a single _bin index,
protocol buffers, and python client.  A regular get() is about 40 ms.  How
can I get faster access with 2i?

Subject:  Secondary Indexes - Feedback?

Hello Riak Users,

The Basho team recently released Riak 1.0 which introduced a new
feature called Secondary Indexes. This feature allows you to tag Riak
objects with additional metadata, and then later query the indexed
metadata to retrieve the objects.


Now that you've had a few weeks to investigate and experiment with
Secondary Indexes, I'm hoping to hear about your experiences to help
us focus future development efforts most effectively:
* Have you tried Secondary Indexes?
* Does the feature help solve your problems? If not, why not? Any concerns?
* What is your wish list for the future of Secondary Indexes?
Please feel free to respond either publicly or privately to this
email, and thanks for your help!
