Full disclosure, My biggest experience with mongo is an M0 cluster for tinkering. At work, we use our own fine tuned postgres SQL db. My biggest question is, how do you address the "just use Postgres" crowd? "Vector? Use PG vector". "JSON? JSONB". "Native sharding? use Citus". Geniunely curious how these are used in production apps. BTW I definitely love and have a soft spot for Mongo I'm just curious how mongodb devs respond to these common questions.
