This blog post introduces upper/db, a data access layer written in Go with ORM-like features. It is now compatible with CockroachDB and has an adapter available for use. The author provides an example of how to connect to a local insecure node using the cockroachdb adapter. Transactions are also discussed, highlighting upper/db's client-side retry handling logic. A Hello World example demonstrates building a Go app with CockroachDB and upper/db.
