Accessing existing obj in pre commit?

Well, I worked around my last issue and I'm looking at risk again, in order to use the disambiguating logic I want I need to do a pre commit validation that involves the new state that is being committed and the old state that is currently stored. I believe couch gives you both of these in pre

Re: Secondary indexing

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: https://github.com/williamsjj/txriakidx Nor sure if that will help...it's reas

Secondary indexing

In my application, I have a frequent need to store collections of data where I rarely access the items individually, but much more commonly in aggregate form. In principle, the mapreduce feature is well suited to this, but it must be fed a set of {bucket,key} pairs to consume, and maintaining these

Re: How to install an erlang module for use with map reduce

There is a good description of how to do it two ways here: http://contrib.basho.com/usage.html You can do it on the fly, but for most purposes adding the add_paths directive to your app.config in the riak_kv section ({add_paths, "/path/to/modules"},). Riak will load the Erlang modules located in

How to install an erlang module for use with map reduce

I am sure this is written down somewhere but I can seem to find it with Google. Where do I install an erlang module so that I can use it with a mapred query? Thanks, Eric Moritz ___ riak-users mailing list riak-users@lists.basho.com http://lists.basho.

Re: riaksearch + mapreduce cannot query more than 20K entries

You need to increase the amount of memory allotted to the JS VMs, the relevant setting is js_thread_stack in the riak_kv section of your app.config. I would suggest increasing this to 32 or 64 to start, you may always want to increase the heap size as well as the number of VMs. You can find more
