# Connector Templates in Action

A JDBC sink connector has dozens of properties, which is where self-service provisioning stalls and the tickets start. In this demo we show how a connector template codifies the handful of settings that actually need Kafka Connect expertise, so a developer supplies only the part they know.

## What You'll Learn

- How a template fixes the settings that need Connect experience, like `upsert` keyed on the record key, `auto.create`, and `auto.evolve`
- How the developer starts from a vetted connector class instead of a blank form
- What's left for the developer to fill in: the source topic and where the data is going
