I find it ironic that one of Uber's original impetus for migrating off Postgres (which I still have serious doubts about) was not being able to "trust" the system [1]. Given my limited failed experience with playing with docker + postgres (and various volume stores including flocker) I have continued doubts about Uber's choices. I suppose they are having success but I wonder at what cost. Specifically the quote on [1]: Finally, our decision ultimately came down to operational trust in the system we’d use, as it contains mission-critical trip data. Alternative solutions may be able to run reliably in theory, but whether we would have the operational knowledge to immediately execute their fullest capabilities factored in greatly to our decision to develop our own solution to our Uber use case. This is not only dependent on the technology we use, but also the experience with it that we had on the team. [1]: https://eng.uber.com/schemaless-part-one/ https://eng.uber.com/schemaless-part-one/
