Don’t need a full blown ORM, just need to execute `select *` queries and load records into memory

Are you sure you need relational database? If you just have a single "table", consider using Xodus for key-value base. It is embedded. As for single requests, you can use something like Jooq query builder, or the one in Exposed.

Anyway, I am not sure it is related to `datascience` topic

This isn’t related to `datascience` topic as well and I don’t think there’s `#xodus`  yet. but do you guys have any idea about the difference of <https://github.com/JetBrains/xodus#environments> and <https://github.com/JetBrains/xodus#entity-stores>?

Oops, nevermind, its in their wiki here: <https://github.com/JetBrains/xodus/wiki/Entity-Stores>
