Replicate PostgreSQL to Amazon Redshift in minutes

As organizations are rapidly moving on their digital transformation journey, it is essential to get the maximum benefit of modernizing analytics in the cloud and unleash the full potential of the available data.

PostgreSQL is one of the very popular databases for data-driven companies. It handles analytical workloads and high levels of concurrency. But when it comes to delivering analytical insights on large volumes of data it becomes slow and fails to scale. Redshift is built to manage very large data sets and perform high-performance analysis. Replicating your data from PostgreSQL to Amazon Redshift will give you access to well-structured data for analytics. Move your data from PostgreSQL to Amazon Redshift on a continuous basis to have the most updated insights on your business.

In this article, we will show you two approaches to replicate your PostgreSQL data to Redshift. Find out how you can set up PostgreSQL-Redshift integration and which approach suits the best for your business.

Why integrate PostgreSQL to Amazon Redshift?

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 Amazon Redshift is the right choice. Integrating PostgreSQL data to Redshift will also serve as a single source of truth for your data analysts and will also help you with reporting processes for unified enterprise analytics. This will also allow you to consolidate all your data sources maybe it be marketing, sales, service, and support in Redshift, and get a complete and clear understanding of your business processes.

PostgreSQL Overview

PostgreSQL is an advanced, enterprise-class open-source relational database that supports both relational and non-relational querying. It is a highly stable database management system, backed by an experienced community of developers which has contributed to its high levels of resilience and integrity. PostgreSQL is used as the primary data warehouse for several web, mobile, and analytics applications. PostgreSQL supports advanced data types and performance optimization features, which are available in expensive commercial databases.

Redshift Overview

Amazon Redshift is a cloud-based data warehouse solution offered by Amazon. The platform provides a storage system that lets companies store petabytes of data. Redshift takes full advantage of Amazon’s cloud server infrastructure for big data as it can scale easily because of the modular node design. It is a fully managed warehouse, so administrative tasks like configuration, maintenance backups, and security are completely automated. Amazon Redshift offers the performance, speed, and scalability required to address your data warehousing and ETL needs.

How to replicate  PostgreSQL to Amazon Redshift?

Here’s an overview of the two approaches you can use to replicate PostgreSQL to Amazon Redshift. 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 one after the other. You need to extract data using PostgreSQL APIs & then connect it properly with the Redshift data warehouse. This whole process to build a custom data pipeline requires regular intervention that makes it cumbersome.
