FabricSync 2.1.0

Fabric BigQuery Data Sync Utility

Fabric BQ (BigQuery) Sync

This project is provided as an accelerator to help synchronize or migrate data from Google BigQuery to Fabric. The primary use cases for this accelerator are:

• BigQuery customers who wish to continue to leverage their existing investments and data estate while optimizing their PowerBI experience and reducing overall analytics TCO
• BigQuery customers who wish to migrate all or part of their data estate to Microsoft Fabric

Getting Started

The accelerator includes an automated installer that can set up your Fabric workspace and install all required dependencies automatically. To use the installer:

1. Download the Installer Notebook
2. Import the installer into your Fabric Workspace
3. Attach the installer to a Lakehouse within the Workspace
4. Upload your GCP Service Account credential json file to OneLake
5. Update the configuration parameters:
   • loader_name – custom name for the sync operation used in dashboards/reports (ex: HR Data Sync, BQ Sales Transaction Mirror)
   • metadata_lakehouse - name of the lakehouse used to drive the Fabric Sync process
   • target_lakehouse - name of the lakehouse where the Fabric Sync data will be landed
   • gcp_project_id - the GCP billing project id that contains the in-scope dataset
   • gcp_dataset_id - the target BQ dataset name/id
   • gcp_credential_path - the File API Path to your JSON credential file (Example: /lakehouse/default/Files/my-credential-file.json")
6. Run the installer notebook

The installer performs the following actions:

• Create the required Lakehouses, if they do not exists
• Creates the metadata tables and required metadata
• Downloads the correct version of your BQ Spark connector based on your configured spark runtime
• Downloads the current Fabric Sync python package
• Creates an initial default user configuration file based on your config parameters
• Installs a fully configured and ready to run BQ-Sync-Notebook into your workspace

Project Overview

For many of our customers, the native mirroring capabilities in Fabric are one of the most exciting features of the platform. While Fabric currently supports a growing number of different mirroring sources, BigQuery is not yet supported. This current gap in capabilities is the foundation of this accelerator.

The goal of this accelerator is to simplify the process of synchronizing data from Google BigQuery to Microsoft Fabric with an emphasis on reliability, performance, and cost optimization. The accelerator is implemented using Spark (PySpark) using many concepts common to an ETL framework. The accelerator is more than just an ETL framework however in that it uses BigQuery metadata to solve for the most optimal way to synchronize data between the two platforms.

Features & Capabilities

Within the accelerator there is an ever-growing set of capabilities that either offer feature parity or enhance & optimize the overall synchronization process. Below is an overview of some of the core capabilities:

• Multi-Project/Multi-Dataset sync support
• Table & Partition expiration based on BigQuery configuration
• Synching support for Views & Materialized Views
• Support for handling tables with required partition filters
• BigQuery connector configuration for alternative billing and materialization targets
• Ability to rename BigQuery tables and map to specific Lakehouse
• Complex-type (STRUCT/ARRAY) handling/flattening
• Support for Delta schema evolution for evolving BigQuery table/view schemas
• Support for Delta table options for Lakehouse performance/optimization
• Automatic Lakehouse table maintenance on synced tables
• Detailed process telemetry that tracks data movement and pairs with native Delta Time Travel capabilities
