How to Replicate Data from PostgreSQL to Amazon Redshift Pairing Redshift with Postgres keeps your data safe and applications running. Postgres is known for its ability to handle concurrency, but as your data load grows, you risk crashing your production database while running analytical workloads. This results in slow queries, especially during exploratory or optimization-discovery phases. With Postgres, you have no control over the fact that you must fetch all 100 columns for all 10 million rows, because columns are a substructure of each row. Imagine you have a massive table with 100 columns and 10 million rows, but you only care about 5 columns. Again, as a row-based database, PostgreSQL fails to scale as effectively as the columnar-based Redshift. Redshift is a Massively Parallel Processing machine, which allows it to deliver insights in a fraction of the time. However, as a row-based database, it’s slow to deliver analytical insights on large volumes of data. PostgreSQL is highly customizable for sophisticated analytical projects. For companies with mid to large volumes of data, we recommend using both tools. PostgreSQL and Redshift serve two separate functions. Getting the most out of PostgreSQL and Redshift.How to Replicate Data from PostgreSQL to Amazon Redshift.But first, let’s look at why you should replicate your data to Redshift. In this guide, we’ll look at four ways how you can replicate data from PostgreSQL to Redshift. That’s why many companies choose to replicate their Postgres DBs to Redshift.
Its columnar structure makes it ideal for processing large volumes of data for analytics and insights. Redshift is the top choice for cloud-based data warehouses. Postgres’s biggest limiting factor is scale: As a row-based RBDMS, it slows to a crawl as your database grows. It’s also a popular production database for data-driven companies in every industry.īut no database is perfect. That makes PostgreSQL (also called Postgres) a popular DB for scientific research and AI/ML projects. The open-source tool is one of the most powerful databases on the planet, with the ability to handle sophisticated analytical workloads and high levels of concurrency. PostgreSQL is the preferred platform of millions of developers around the world.
