Just to clarify: I'm not saying there is a significant difference between map views and indices, I'm saying I prefer the directness of programming with them over trusting the query planner and table statistics. In couch, to do a table scan, I need to program it as such, otherwise I'm forced to use a view - things like forgotten indices for some edge cases are impossible. Sure takes longer to do things, but when performance issues arise it's easy to reason about while with SQL based DBs I've seen a lot of time being spent at that stage. They work well 99%, and then that remaining 1% takes 99% of your time. |
