Building your modern crud app is still incredibly hard to get right while still being performant in any language. IMO, neither ruby nor the database are at fault.

- Materialization pipelines are hard, especially ones that need transactional constraints.

- Passing async connections from the http request all the way through to the database is hard.

- Data distributions can change which can impact indexes, join ordering, and the optimal materialization pipeline.
