We implemented a scheme for maintaining secondary indexes using
MapReduce and KeyFilters. It's written in Python but there's a
description of how the design works and a test script for validating
other implementations:

Hi David,
If you want both good performance and reliability you might look at somebody
like SoftLayer who will let you mix and match cloud and dedicated servers to
meet your needs. Both they and Voxel have cloud servers that beat the pants off

Is it possible to add a link phase when using key filters? Currently,
just using key filters combined with a reduce phase (built-in reduce
identity). Would like to add a link phase to pull all the linked keys
and pass them to the identity reduce as well. Thank you in advance.

Hi Guys,
I've put together a library for my company's needs to implement
secondary indexes in Riak transparently. It's built on top of Ray
Cote's great txRIak library, and should drop in transparently anywhere
txRiak is used. We've open sourced it in case it's useful for anyone

Through trial and error I think I've found the cause of my error...the
tokenize function. Is it possible to log the output of tokenize in a
job to compare what I think it should be outputting to what it

Hi,
I'm experimenting using key filters to implement indexes. My approach
is for each data key in bucket A, to create a new empty key in a
dedicated index bucket where the original key name and value of the
indexed field is encoded in the key name for a new index key.
Data key looks like this:

Hello,
I've been playing with implementing streaming support in the txRiak
library. However, I've noticed that when a map reduce error occurs
during a streaming map/reduce, Riak doesn't wrap the error in the

My benchmarks with Riak against Redis showed Riak is fast, but it's
never going to be as fast for caching as an in-memory only store that
doesn't have to do coordination. That said if your data set is larger
than RAM, Riak will likely be faster as it will scale to handle that
better.

Honestly the holding back of replication from Riak OS is the only real downside
to the product. Reminds me of the old adage there's those that will never pay
for OS software...and those that can't afford not to (because of things like

Hey Justin,
Since Riak is lockless, what is the best approach to pulling a
distributed FS snapshot of the bitcask files across nodes? I assume if
they're not close to each other, you'll have an issue if you have to
restore a cluster.

Is it smart enough to coordinate with the other partitions to ensure
not more than 25% (just a plug number) of the partitions are
compacting at the same time? It would seem to me there's the
possibility for a performance drop if you had the perfect storm of too

Does the bitcask back end handle crash recovery as well as the
