scalability: All content tagged as scalability in NoSQL databases and polyglot persistence
When reading it, I’ve jotted down:
- The good: using a combination of cloud and a NoSQL database (Couchbase) allowed OMGPOP to scale
- The bad: OMGPOP had to call in people from Couchbase to help out with scaling
Question is if you can throw in more iron and hire experts wouldn’t many other database solutions be able to cope with OMGPOP’s growth?

Interesting answers on Quora mostly expanding on Krishna Sankar’s short answer:
There are two ways one can address large scale computational problems:
- Task Parallelism : This is where MPI and so forth fit in
- Data Parallelism : This is the sweet spot for map/reduce

How many times have you got an answer that applies to your specific scenario when providing a short list of performance and scalability requirements? MySQL/InnoDB can do 750k qps, Cassandra is scaling linearly, MongoDB can do 8 mil ops/s. Is any of these the answer for your application?
How many times did you get all the requirements right at the spec time?
How many times did requirements remain the same during the development cycle?
How many times did production reality confirmed your bullet list requirements?
