7±2 things you didn't know about Exposed
summary
Seven concrete takeaways about Exposed include how many‑to‑many uses the via function to infer join columns, date handling requires choosing Joda Java time or kotlinx‑datetime, and logging differentiates between the transaction logger and prepareSQL which returns SQL with placeholders not parameters. Coroutine support uses newSuspendedTransaction with subtle nesting semantics that can reuse or create independent transactions. There are typed null literals, entity mapping helpers that avoid detached entities, entity hooks for auditing, and an exec escape hatch.
