# Portal batch processor

> Run Portal-native Squid SDK data sources with @subsquid/batch-processor.

Substrate squids do not use the Portal-native `@subsquid/batch-processor` runner. They configure a `SubstrateBatchProcessor` and drive it with `processor.run(db, handler)` — see the [Substrate processor reference](./substrate-processor/general). The `run()` machinery documented here applies to Portal-native chains only.
