Connector SDK v2: write a source in 80 lines

Connector SDK v2 ships today. If you wrote a v1 source, migration is mechanical — a one-day task for most sources.

import { defineSource } from "@dxdata/sdk";

export default defineSource({
  name: "postgres",
  async discover({ config }) { /* ... */ },
  async snapshot({ table, since }) { /* ... */ },
  async stream({ table, cursor }) { /* ... */ },
});

What changed

The biggest change is that the SDK now owns backpressure, retry, and checkpointing. You describe the three lifecycle hooks; the SDK runs them. This removed the majority of custom error-handling code from every source we have seen in the wild.
