RethinkDB is my favorite piece of my current tech stack. I tell everybody I know about it, and I'm soon to release some blog posts and speak at a Meetup showing off what it is good at and how to get started - I really just can't say enough good stuff about these guys. A high level overview from someone who has used it in production since 1.10 (about six months): Pros: * ReQL is a beautiful DSL that makes querying and using my data simpler than anything I've ever had before. * An amazing UI lets you quickly do the things you do the most (verify a query, cherry pick some results, add/drop tables, indexes, shards, etc). * Unparalleled support. During almost any reasonable hour, a RethinkDB employee will quickly field any question you have on #rethinkdb (freenode), their User Group, or email. * Quick releases. These guys ship major releases every 60 to 90 days. Each release offers huge features, performance improvements, and bug fixes. They do a great job of listening to what people want and implementing them fast. Cons: * Database is still technically "beta" - great for side projects and prototyping, but be mindful if you intend to use it in production. * Works great on tables of a few GB, but performance really degrades on the next order of magnitude. It looks like there were major changes in 1.12 addressing this. * Only three officially supported clients (JS, Python, Ruby). That's a good start for their target market, but it is limiting for some. RethinkDb is an archetype for startups - building what people want, shipping fast, always talking to customers, and clearly passionate about what they do. Even if you don't use their product, we all can learn from these guys. I hope they do well.
