Migrating from Mongo to Riak at Shareaholic
basho.comVery interesting. I wonder if they tried running MongoDB on SSD. I would think that might mitigate having to have their working set in memory and potentially make the cold start problem a bit better. It'd certainly seem easier than migrating datastores.
Thanks for watching. We didn't try running Mongo off of SSDs. We're on AWS, and we were using Mongo long before SSD storage was available. I suspect SSDs would help quite a bit with cold starts, albeit at a significant additional cost.
If anybody would like a copy of the slides (sans video), I've made them available here: http://rob.by/2012/migrating-to-riak-at-shareaholic
Overall a great talk by @freerobby. One little nit... The Riak search feature is not built on lucene but modeled after it in terms of api. The search itself is not as robust as lucene but useful for most applications.
Thanks for the clarification. I got confirmation on this from Ryan Zezeski as well. Riak-search used to be built on Lucene, but now it's all built by Basho, using Lucene's query syntax.
