Multiple datasets for Actors

Actors can now output to multiple datasets, each with its own schema and validation rules. Keep your data clean, structured, and purpose-built.

Website Content Crawler  uses multiple datasets to store details about URLs it failed to scrape, making it easier to debug crawl issues without digging through the main output.

• Define datasets in actor.json under storages.datasets
• Each key becomes an alias that refers to that dataset within the run
• A default alias is required; all others are optional
• Each dataset automatically follows the run’s data retention policy
• Reference datasets in your output schema via template variables, e.g. {{storages.datasets.categories.apiUrl}}

• JS SDK ≥3.7.0: await Actor.openDataset({alias: 'categories'})
• Python SDK ≥3.3.0: await Actor.open_dataset(alias='categories')
• Without SDK: Read dataset IDs from the ACTOR_STORAGES_JSON environment variable
