Google Cloud Platform has a robust architecture with a petabyte-scale data warehouse known as BigQuery to perform analytics on the data. Many organizations are moving their on-premise systems to BigQuery because of its exceptional performance over data.

In this blog, you will learn about the best BigQuery ETL tools in the market that you can use to load data into BigQuery.

What is BigQuery?

BigQuery is a serverless, scalable cloud-based data warehouse provided by Google Cloud Platform. It is a fully managed warehouse that allows users to perform ETL on the data with the help of SQL queries. You can unleash the power of SQL and the performance and scalability feature of Google Cloud Platform to perform ad-hoc analytics on your data. BigQuery can load a massive amount of data in near real-time.

Key Features of BigQuery

Some of the key features of Google BigQuery are listed below:

  1. Scalable Architecture: BigQuery offers a petabyte scalable architecture, and is straightforward to scale as per needs. 
  2. Faster Processing: BigQuery can execute SQL queries over petabytes of data in seconds. You can run analysis over millions of rows without worrying about scalability.
  3. Fully Managed: BigQuery is a fully managed and serverless architecture. It automatically manages the up-scale or down-scale of the cluster.
  4. Security: BigQuery provides the safety of sensitive data when data is in in-flight as well as at rest. The tables and the data are compressed and encrypted to ensure the utmost security.
  5. Real-time data ingestion: BigQuery can perform real-time data analysis, thereby making it famous across all the IoT and Transaction platforms.
  6. Fault Tolerance: BigQuery offers replication that replicates data across multiple zones or multiple regions. It ensures consistent data availability when the region/zones go down.

What is ETL?

ETL is an abbreviation for Extract, Transform, and Loading. With the introduction of cloud technologies, many organizations are trying to perform ETL to migrate their data. They often have data storage as an RDBMS or legacy system which lacks performance, scalability, and fault-tolerant systems. Hence, to get all these features, organizations are migrating data to cloud technologies, like the Google cloud platform.

How to Select the Best Google BigQuery ETL Tools

Here are some factors to help you select the appropriate one from the many available BigQuery tools in the market.

Data sources

The greatest data-driven insights should be built on top of your BigQuery data. Tools that don’t offer mission-critical app data integration capabilities won’t give your team the 360-degree perspective they require.


Seek a solution that can expand with you and support the data pipelines you now use. Select a BigQuery tool that can accommodate a range of use cases and procedures, as well as the numerous sources and SaaS applications you may require in the future.

Customer support

The majority of your data engineering team’s work should be focused on using the data rather than transferring it across locations. The top ETL tools will assist you with this procedure by providing practical guidance.


Of course, budgets are vital, but for many teams, even more crucial is a pricing model that is simple to comprehend and anticipate. It might be challenging to project expenditures for consumption-based pricing from one billing cycle to the next since it can vary each month.
