Create a Hybrid Database Solution with Firebase Firestore and BigQuery

How to create a hybrid database solution using Firebase Firestore for real-time data and BigQuery for analytics and reporting. This solution is ideal for applications that need fast, real-time updates combined with powerful analytical capabilities.
 

Prerequisites

Before you begin, ensure you have the following:

• A Google Cloud Platform (GCP) account.
• Basic knowledge of Firebase and BigQuery.
• Node.js and npm installed on your local machine.
• Firebase CLI installed.

Step 1: Set Up Firebase Firestore

Create a Firebase Project:

Go to Firebase Console.

Click on "Add Project" and follow the setup instructions.

Enable Firestore:

In the Firebase Console, navigate to "Build" > "Firestore Database."

Click on "Create Database" and select a suitable mode (Start in production mode is recommended for live projects).

Add Data to Firestore:

Go to the "Firestore Database" section.

Click on "Start Collection" to create a collection and add sample documents.

 

Step 2: Enable BigQuery Integration

Link BigQuery to Firebase:

In the Firebase Console, go to "Build" > "Firestore Database."

Click on the gear icon in the top right corner and select "Project Settings."

Under "Integrations," enable BigQuery.

Set Up BigQuery Dataset:

• Go to the BigQuery Console.
• Confirm the linked dataset created by Firebase.
• Review the dataset to ensure data is syncing correctly from Firestore.

Step 3: Sync Firestore Data to BigQuery

Firestore automatically syncs data to BigQuery if the integration is enabled. Follow these steps to confirm:

Verify the Dataset:

• Open the BigQuery Console.
• Locate the dataset linked to your Firebase project.

Explore Synced Tables:

Each Firestore collection will have a corresponding table in BigQuery.

Open a table to view the synced data.

 

Step 4: Query Data in BigQuery

Write SQL Queries:

In the BigQuery Console, click on "Compose New Query."

Use SQL to analyze the Firestore data. For example:

SELECT COUNT(*) AS total_documents
FROM `your_project_id.your_dataset_id.collection_name`
WHERE status = 'active';

Save and Share Queries:

Save queries for reuse or share with team members.

 

Step 5: Automate Data Transformation (Optional)

Create a Dataflow Pipeline:

• Use Google Dataflow for complex data transformations.
• Transform and load processed data into a new BigQuery table.

Set Up Scheduled Queries:

In BigQuery, create scheduled queries to automate regular reporting or analytics tasks.

 

Step 6: Visualize Data with Google Data Studio

Connect BigQuery to Data Studio:

1. Go to Google Data Studio.
2. Create a new report and add BigQuery as a data source.

Build Dashboards:

• Use charts, tables, and filters to visualize your data.
• Customize the dashboard to meet your reporting needs.

Step 7: Secure Your Solution

Set IAM Permissions:

• In the GCP Console, go to "IAM & Admin."
• Assign roles to team members, limiting access to Firestore and BigQuery as necessary.

Enable Billing Alerts:

• Set up budget alerts in the GCP Billing Console to avoid unexpected costs.

By integrating Firebase Firestore and BigQuery, you can create a hybrid database solution that leverages Firestore's real-time capabilities and BigQuery's analytical power. This setup is ideal for applications requiring both fast, real-time updates and deep data analysis.  Hope this is helpful, and I apologize if there are any inaccuracies in the information provided.
