Re: MapReduce - sorting via the Java client

I was researching the same question and found the answer after some tinkering around. You need a JS source function. You must write the JS source code for the sort algorithm too. JSSourceFunction phaseFunction = new JSSourceFunction( "function(v) {" + "return v.sort(functio

Re: Evolving data model

It really depends on your use case. Guido's tips on not-null and ignore-properties will help. With *JsonIgnoreProperties* you can also specify which ones you would like to ignore. That helps check ignoring properties that you know *should* exist. Converting your documents to a new format is a lot

Bug on riak-client 1.0.6 - Riak index property not serialized

I switched to the java riak-client 1.0.6 to take it for a spin, and several test cases of mine failed. Upon further investigation I found that any member variable that contains the @RiakIndex annotation does not serialize into Riak anymore. You can reproduce the problem with the following type @Js

Indexes on 64 bit values

Hi folks, I have a query regarding riak indexes. My current understanding is that riak cannot index numbers whose representation needs more than 32 bits. There is an issue on the basho repo to address this - https://github.com/basho/riak-java-client/issues/112 . Do you have any idea when it will b

Re: Riak Production cluster

There is nothing in particular. Reading through loads of documentation and user experiences on the riak-users list should give you some idea of what to expect. I've been playing around with a production cluster of late. Here are some salient points off the top of my head based on load tests I ran r

Riak and host names

I took the AWS EC2 riak image for a spin today. I have a query regarding riak nodes and how they behave when the machine reboots. When an EC2 instance reboots, the internal ip / internal DNS / external DNS change. This renders the app.config and -name argument on vm.args incorrect. I was exploring

Perhaps I should ask the question differently. Can someone elaborate on what 'cluster replace' does and how the command is affected by node names that change after riak starts up ? Thanks -Deepak On Wed, Jan 2, 2013 at 1:13 AM, Deepak Balasubramanyam < deepak.b...@gmail.com>

A bitcask backend will allow you to set expiry for keys. Using multiple backends allows expired and persistent keys to co-exist. I searched the riak user list and fished out a thread discussing this. Let us know if that is wh
