The most efficient way to get Bluesky data into BigQuery is by consuming the **Jetstream** firehose. It is a compressed, filtered version of the AT Protocol stream that significantly reduces bandwidth and processing costs compared to a full relay sync. You should deploy a lightweight consumer—written in Go or Python—on a service like Cloud Run. This consumer listens for specific event types, batches them into JSON files, and pushes them to a Google Cloud Storage (GCS) bucket. From there, a BigQuery Load Job or the BigQuery Data Transfer Service can ingest the files into your tables. The primary trade-off here is between data volume and query costs. Ingesting the entire global firehose is a waste of resources for most use cases. To keep the project feasible, you must filter the stream at the source for specific collections (like `app.bsky.feed.post`) or specific actors. Additionally, because AT Protocol data is nested JSON, you should use BigQuery’s native `JSON` data type for initial ingestion. This avoids the overhead of complex schema mapping upfront and allows you to flatten only the fields you need for specific reports later. For a production-ready setup, prioritize reliability over complexity. Use a Pub/Sub architecture between your firehose consumer and BigQuery if you need real-time streaming, or stick to GCS batching if hourly updates suffice. Batching is generally more cost-effective for large-scale analytics. Start with a small-scale pilot to
