Why teams connect BigQuery and Notion

Get the data locked inside Notion into BigQuery as live tables, and send results back where Notion can use them, without writing a pipeline.

Whatever Notion is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Databases / Data sources, Properties, Blocks, Formula and Rollup properties from Notion into tables in BigQuery continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in BigQuery can also be written back into fields in Notion where the tool can use them.

Common use cases

  • 01 Two-way sync a Notion projects or tasks data source with a Postgres table so engineers work in SQL while the team edits Pages in Notion, mapping status, date, and assignee properties both ways.
  • 02 Push rows from a warehouse or another database into a Notion data source as Pages so ops and leadership read live metrics in a familiar Notion view.
  • 03 Land CRM and ERP records in BigQuery continuously so dashboards reflect business systems without nightly batch jobs
  • 04 Activate modeled BigQuery tables by syncing computed attributes back into sales and marketing tools

Common sync patterns

History that outlives the tool

A continuously synced copy in BigQuery preserves a queryable record even as data ages out of Notion or gets changed inside it.

Analytics on Notion's data

Records and events from Notion land in BigQuery as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Notion's data with data from every other synced system to answer questions no single tool can.

What you can sync between BigQuery and Notion

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

BigQuery objects Notion objects How this pairing syncs
Datasets Organizational container — you pick which dataset’s tables to sync. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Datasets is specific to BigQuery and Properties to Notion — each maps to any object or custom field on the other side.
Projects Connection scope: the service account grants access per project. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Projects is specific to BigQuery and Blocks to Notion — each maps to any object or custom field on the other side.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Tables is specific to BigQuery and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.
Partitioned tables Synced like regular tables; partition columns map to target fields. Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Partitioned tables is specific to BigQuery and Users to Notion — each maps to any object or custom field on the other side.
Clustered tables Supported; clustering is transparent to the sync. Comments Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system. Clustered tables is specific to BigQuery and Comments to Notion — each maps to any object or custom field on the other side.

How changes propagate between BigQuery and Notion

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

BigQuery Notion Sub-second propagation

DetectionChanges in BigQuery are captured at the source via change data capture — no polling loop against its API. Real-time notification service deployed into your Google Cloud project: Eventarc ("a notification service that enables real-time updates to happen").

DeliveryEach detected change is written to Notion through its API, with automatic retries and rate-limit backoff.

Notion BigQuery Sub-second propagation

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

DeliveryEach detected change is applied to BigQuery as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • BigQuery: Subject to Google Cloud quotas on queries, DML, and streaming; DML is supported but the platform favors append-heavy batch and streaming loads over row-at-a-time writes.
  • Notion: Average of ~3 requests/second per integration with some bursts; 429 with a Retry-After header when exceeded. Payloads capped at 500 KB and 1000 block elements.
