Today I drove up to Boston for the day to attend NoSQL Live . My experience so far within the NoSQL community has been limited to what we've built in-house at Disney and ESPN over the past decade to solve our scaling issues, more recently has been ESPN's use of Websphere eXtreme Scale , and the very latest has been my own experimentation with HBase which hasn't gotten much further than setting up a four node cluster. I've read a little about Cassandra, memcached, Tokyo Cabinet and that's about it. So before the sandman wipes away most of my first impressions of the technologies discussed today, I wanted to record my thoughts for posterity or, at the very least, tomorrow. Cassandra Cassandra seems to be the hottest NoSQL solution this month with press about both Twitter and Digg running implementations. My impression, I'm wary of "eventual consistency". I don't feel I understand the risk and ramifications well enough to design a system properly...
