Replicate PostgreSQL to BigQuery in minutes

PostgreSQL is a widely used open-source relational database management system but sometimes it requires huge efforts and expertise to run analytics queries within the desired time. However, to track all the user events in a timely and safe manner, and let business users query this data in any way possible, moving your data from PostgreSQL to BigQuery is the right choice.  Moving your PostgreSQL to BigQuery doesn’t have to be complex or expensive, Daton simplifies the process to reduce your spending and minimizes the time it takes to deliver value for all your PostgreSQL data. Let’s see how!

In this blog, we will demonstrate how to replicate your PostgreSQL data to BigQuery with best practices, while ensuring data integrity.

Why integrate PostgreSQL to BigQuery?

A lot of times, there is a need to internally move and transform data between multiple data stores. If data is scattered around different information systems, it is hard for a business user to analyze it and make sense of it. Integrate your PostgreSQL data to BigQuery for centralizing all data sources, which will help you to view a consolidated version of the data. Moving PostgreSQL data to BigQuery will further allow the departments to create detailed dashboards that can act as a single source for all customer information from different platforms. 

PostgreSQL Overview

PostgreSQL is an advanced, enterprise-class, and open-source relational database system. It supports both SQL (relational) and JSON (non-relational) querying. PostgreSQL is a highly stable database backed by more than 20 years of development by the open-source community. It’s known for its stability and its ability to handle high volumes of transactions. PostgreSQL is used as a primary database for many web applications as well as mobile and analytics applications.

BigQuery Overview

Google BigQuery is a cloud-based data warehouse service introduced by Google. It is a REST-based web service that allows you to run complex analytical SQL-based queries under large sets of data. Additionally, BigQuery is a serverless, highly scalable, and cost-effective multi-cloud data warehouse designed for business agility. Its fast deployment cycle and on-demand pricing make it one of the highly accessible and popular data warehouses. 

How to replicate PostgreSQL to BigQuery?

Here’s an overview of the two approaches you can use to replicate PostgreSQL data to BigQuery. This will allow you to evaluate the pros and cons of both and choose the one that best suits your requirement.

Build your own data pipeline 

This process needs a lot of experience and consumes a lot of time and manpower. The chances of errors are more due to multiple integrated steps to be executed one after the other. You need to extract data using PostgreSQL APIs & then connect it properly with the BigQuery data warehouse. This whole process to build a custom data pipeline requires regular intervention that makes it cumbersome.
