So basically we need a system where we can have incredible write and read performance but also a system that is elastic in nature. Most importantly, it has to be available. Before I go into more details, MongoDB is great for most people wh…

Now that asyncio is production ready (we really have had a d…

HN discussionAlways see posts with titles such as "Why We Moved From MongoDB to PostgreSQL" and rarely "Why We Moved From PostgreSQL to MongoDB". MongoDB is simply unreliable with data and struggles to scale. A few companies that have moved away from MongoDB: shippable, dzone, theguardian, olery, urban airship, bump, etsy, viber, shareaholic, videoamp, digidoc 1. http://blog.shippable.com/why-we-moved-from-nosql-mongodb-to... 2.…
