Hi! Is there a good persistence library (preferably a Kotlin one) for working with postgres’s json columns?

People (full disclosure: not me) seem to have used #exposed for that, even though it's not yet officially supported: https://github.com/JetBrains/Exposed/issues/127

What precisely are you looking for? I’m using JDBI and it seems to be doing a decent job of serialising/deserialising instances of Kotlin data classes into JSON/JSONB columns… but I’m guessing you might be looking for something more than that…

serialize/deserialize and some form of (basic) querying
and its a plus if its officially supported
What made you guess i’m looking for more 😄?

I definitely recommend checking out JDBI then. It’s a fairly thin wrapper over JDBC which I’ve only just started playing with but it seems to just work and I like it a lot. And the JSON stuff has worked well for me (even though I feel like I’m not doing much with it… just serialising/deserialising to/from Postgres JSON/JSONB column).

(I haven’t tried queries on fields in JSON objects but I assume that’ll work OK as well because that’s handled by the DB and not the library.)
