You can read only database files created by ObjectBox. I do not think that Navicat can read ObjectBox DBs yet, so I would guess you are trying to feed ObjectBox with an alien DB.

Having 230,000 objects is not a challenge. It rather depends on how complex the query is.

No, SQLite DBs cannot be read. We might provide a tool that helps migrating at some point.
