Hey, quick recommendation question.
Embedded DBs?

I want something simple, file based, could be key/value or more complex.
Ideally it would let me serialise custom objects automatically.
Nitrite+Potassium Nitrite seemed perfect, but I'm getting way too many dependency conflicts due to using apache spark in the same project (jackson is being a pain to get right in terms of versions, which breaks all the serialisation for NO2)

This is basically a project that I'm converting form Scala to Kotlin. The scala version used SQLite with an ORM, which is a perfectly reasonable slution. In which case, is there an ORM you'd recommend?

Sorry, this ended up being longer than I expected 😂

Hey there! I am using Kotlin Expose. It´s quite nice so far.
https://github.com/JetBrains/Exposed

Currently supported database dialects:

PostgreSQL
MySQL
Oracle
SQLite
H2
SQL Server

It´sdefinitely worth a look!

Why not continue using SQLLite with Kotlin?

Exposed is a DSL, rather than an embedded DB, but your question ended up a bit unfocused, so answers will be a bit spotty w/o further clarification.

You might also check out Square’s SQLDelight https://github.com/square/sqldelight, @jw gave a great talk about it at KotlinConf last year

If a key/value store and some serialization support is sufficient, I find com.sleepycat:je to be a decent option, too.

And if you want an SQL interface, something like H2 has the advantage over SQLite that it doesn't need native binary libraries.

And also the massive disadvantage that it operates in a managed environment

Depends on what you want and how hard your deployment target makes the integration of native code, I guess.

Thanks for your replies and sorry that the question was a bit all over the place. I'll probably try Exposed with SQLite or H2. I completely forgot about H2. I used it before and actually might fit the bill! 👍
