Why teams connect BigQuery and Tableau

Flow Tableau data into BigQuery in real time — no exports, no schedulers, no custom scripts.

Tableau is a read-only source: Stacksync reads its data in real time and delivers it into BigQuery, so BigQuery always reflects the current state of Tableau — without exports, scripts, or schedulers.

Tableau is where teams explore, visualize, and report; BigQuery is the store of record that holds the raw tables and full history behind those views. The two overlap wherever the same events, users, and metrics matter to both, and when the bridge between them is a nightly export or a hand-built extract, dashboards lag the warehouse and analysts spend the morning arguing over whose number is right.

Common use cases

  • 01 Read Databases, Tables, and Fields from the Metadata API to populate a data catalog with Tableau lineage and column definitions.
  • 02 Mirror the Projects and Workbooks content hierarchy into an internal catalog so teams discover dashboards from a central index.
  • 03 Maintain a customer master table in BigQuery joined across CRM, billing, and support sources
  • 04 Feed ML feature tables in BigQuery from operational systems on a continuous schedule

Common sync patterns

One number both sides agree on

Metrics and aggregates stay aligned between the two systems, so a figure shown in Tableau matches the BigQuery table it was built from instead of drifting between refreshes.

Where BigQuery holds the source tables: live data in the reporting layer

Records maintained in BigQuery flow into Tableau as they change, so dashboards and reports read current rows rather than an overnight extract.

Where Tableau produces segments or scores: results back to the warehouse

Cohorts, segments, and computed metrics defined in Tableau write to BigQuery as tables the rest of the stack can query and join.

What you can sync between BigQuery and Tableau

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 Tableau objects How this pairing syncs
Projects Connection scope: the service account grants access per project. Projects Folders that organize content and set permissions; listed via REST to mirror the site's content hierarchy into a catalog. Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction.
Clustered tables Supported; clustering is transparent to the sync. Extract Refresh Tasks Scheduled extract refreshes; status and history read via REST, with DatasourceRefreshSucceeded and Failed events delivered by webhooks. Clustered tables is specific to BigQuery and Extract Refresh Tasks to Tableau — each maps to any object or custom field on the other side.
Datasets Organizational container — you pick which dataset’s tables to sync. Fields and Columns Columns and calculated fields with their descriptions, exposed by the Metadata API; read to populate a data catalog with governed definitions. Datasets is specific to BigQuery and Fields and Columns to Tableau — 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. Published Data Sources Published data sources (.tdsx); their underlying rows are read via the VizQL Data Service, and refresh state is tracked through content webhooks. Tables is specific to BigQuery and Published Data Sources to Tableau — each maps to any object or custom field on the other side.
Partitioned tables Synced like regular tables; partition columns map to target fields. Workbooks Workbook content and metadata read via the REST and Metadata APIs; create, update, and delete events fire webhooks for change detection. Partitioned tables is specific to BigQuery and Workbooks to Tableau — each maps to any object or custom field on the other side.

How changes propagate between BigQuery and Tableau

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 Tableau 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").

DeliveryTableau does not accept inbound record writes, so this direction carries requests rather than records: Tableau's output flows back as field updates on the originating BigQuery records.

Tableau BigQuery Sub-second propagation

DetectionTableau notifies Stacksync of record changes through webhook events. Webhooks fire on workbook and data source create/update/delete and extract refresh events.

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.
  • Tableau: Tableau Cloud enforces per-site REST rate limits and returns HTTP 429; a PAT allows only one concurrent session and expires after 15 consecutive days of non-use.
