Ideas to ask speakers
It would be great if you could investigate a couple of interesting technologies and report back:
1. Basho have recently carved out riak-core out of Riak to provide a common platform to build distributed services and the DB has become an app on top of riak-core (also called Riak KV); they then released Riak CS which is a cloud storage system built on top of riak-core. It would interesting to know more about riak-core and what it can do. And of course Riak CS.
2. They are currently integrating SOLR into Riak to provide distributed search capabilities. That is definitely worth having a look at.
Thare, you go, that's at least 3 interesting articles you can come back with :-)
