Why do we always go from one extreme to the other. Mongo is great at handling large volumes of schema-less data. Relational database are great at connecting two datasets. If you are just using one table with two fields (id/value and value contains a json object that changed) for logging perhaps a relational database isn't the right choice. Redis might be better / mongo might be better depending on what comes next. Let's stop the next cycle where everyone moves to postgres for everything only to throw it away for the next thing. I was using postgres in 2008 and it was great.. why did it take until 2019 for everyone else to discover? We are in the peak postgres cycle. I hope it doesn't get disgarded when the serverless hype kicks into gear.
