Set up a source connector for Google Analytics 4 Bigquery Exports in minutes. Estuary supports streaming (including CDC where available) and batch data capture through events, incremental syncs, or snapshots — without custom pipelines, agents, or manual configuration.
- 2
Configure Google GCS Parquet as your destination connector
Estuary supports intelligent schema handling, with schema inference and evolution tools that help align source and destination structures over time. It supports both batch and streaming data movement, reliably delivering data to Google GCS Parquet.
- 3
Deploy and Monitor Your End-to-End Data Pipeline
Launch your pipeline and monitor it from a single UI. Estuary guarantees exactly-once delivery, handles backfills and replays, and scales with your data — without engineering overhead.

Google Analytics 4 Bigquery Exports connector details
The Google Analytics 4 BigQuery Exports capture connector in Estuary captures GA4 data from the daily export tables created in BigQuery and loads it into Estuary collections. It supports GA4 event, user, and pseudonymous user data, making it useful for moving analytics data into warehouses, databases, and other downstream systems for reporting, modeling, and analysis.
- Captures GA4 daily BigQuery export tables for events, users, and pseudonymous users
- Automatic discovery of GA4 export datasets and supported stream types
- Scheduled polling, with a default daily capture schedule that can be customized
- Handles late-arriving GA4 events by re-capturing recent daily tables within a configurable window
- Configurable minimum date to limit the amount of historical data scanned during the initial backfill
- Service Account or Google Cloud IAM authentication for secure access to BigQuery
By default, the connector maintains a four-day live window so it can capture late-arriving events that GA4 may add to recent daily tables. You can also adjust the polling schedule and live-window behavior based on freshness and BigQuery scan-cost requirements.

Google GCS Parquet connector details
The Google Cloud Storage Parquet materialization connector in Estuary writes delta updates from Estuary collections into Apache Parquet files in a Google Cloud Storage bucket. Updates are batched within Estuary, converted to Parquet, and uploaded to GCS at a configurable interval for analytics, data lake, and downstream processing workloads.
- Materializes delta updates from Estuary collections as Apache Parquet files
- Configurable upload interval, with a default of 5 minutes
- Configurable file-size limit, defaulting to approximately 10 GiB
- Configurable row group size, including row-count and byte-size limits
- Optional GCS object prefix for organizing materialized files
- Configurable destination path for each Estuary collection
- Automatic mapping of Estuary data types to Parquet data types
- Google Cloud service account authentication
- Requires
**roles/storage.objectCreator**permission on the destination bucket
Each Estuary collection produces a sequence of separate .parquet files rather than one continuously updated file. Files use monotonically increasing, zero-padded names so they remain lexicographically sortable, and a new version path is created when a binding is re-backfilled.
