Google BigQuery has become a dominant leader in the world of big data.
But that data only works if you can collect and analyze metrics from every data source that matters to your business. And to do that, you'll need the right ETL tool.
Today, we'll look at the best ETL tools for Google BigQuery, which ETL solutions are best for your use case, and how to choose the right platform for your business case.
BigQuery is a serverless, scalable, fully managed cloud data warehouse that's part of the Google Cloud Platform (GCP).
Users can create ETL pipelines with SQL using Google's integrated tools or third-party platforms.
You can access BigQuery through the cloud console, command line tool, or REST API.
BigQuery connects with most major business intelligence tools to deliver data insights in a visual dashboard.
BigQuery offers superior performance, scalability, and speed compared to platforms like SQL Server. That's because of its fully managed architecture which handles backend tasks automatically to improve performance.
Google offers several ETL tools, including Dataflow and Data Fusion, but third-party tools offer more flexibility.
Whether you want ETL (extract, transform, load) or ELT (extract, load, transform) processes, you can find a tool that works with BigQuery.
BigQuery is one of the most popular data warehouses, but it's not the only one. It's in a crowded field with competition from other players like Snowflake, Amazon Redshift, and Microsoft Azure Synapse Analytics.

On-demand analysis: Free for 1TB/month; $5.00/TB thereafter
Flat-rate: Based on pre-committed amounts, with steep discounts for larger commitments
BigQuery divides its storage and compute resources, which means handling computations where the data is instead of needing to replicate it somewhere else.
Serverless architecture means you don't need to worry about allocating clusters or resources to individual processes.
Machine learning built-in with SQL queries, letting you access much more advanced features without needing to learn a new skill set.
BigQuery is a OLAP (Online Analytical Processing) solution, which works best with relatively infrequent database writes and can handle much more frequent reads.
Support for JSON functions through SQL queries.
Seven-day history of changes made to BigQuery tables.
BigQuery Sandbox for using BigQuery and other Cloud Console apps without any commitment.
BigQuery only works with Google Cloud infrastructure.
"Black box" serverless architecture determines your settings automatically, giving you less flexibility and control.
More expensive than competitors.
BigQuery is best for teams looking for a powerful cloud-based data warehouse with less management requirements.
BigQuery's managed platform, serverless architecture, and low administrative overhead mean less time overseeing infrastructure and more time using the platform.
And of course, BigQuery is an obvious option for data teams fully committed to the Google Cloud Platform ecosystem.
If you're choosing a BigQuery ETL tool, there are a few features to pay careful attention to. Each solution has its advantages and disadvantages.
For the best insights, your BigQuery data should have a complete picture. Tools that lack the data integration features for mission-critical apps aren't going to deliver the 360-degree view your team needs.
Look for a tool that not only supports the data pipelines you need now, but can grow with you in the future.
Choose a tool that can support various use cases and workflows, and support future data sources and SaaS apps you'll use down the road.
Your data engineering team should spend most of its time leveraging the data, not moving it from one place to the next. The best ETL tools will offer hands-on support to help guide you through this process.
Budgets matter, of course, but even more important for many teams is a pricing model that's easy to understand and predict.
Consumption-based pricing can change every month, making it hard to estimate costs from one billing cycle to the next.
Portable is the most ideal BigQuery ETL tool for long-tail data sources.
Portable has 300+ hard-to-find long-tail connectors for the kind of SaaS apps that most enterprise applications don't support.
Portable will also develop custom connectors for apps you can't find anywhere else. Share the details on the ETL pipeline you need to set up, and the Portable team can deliver a connector in as little as a few hours.
Plus, the team handles all maintenance, alerting, monitoring, and troubleshooting so you don't have to. When APIs change, Portable will repair connectors so they keep working---and so you can rest easy.
Portable offers a free plan for manual data workflows with no caps on volume, connectors, or destinations.
For automated data flows, Portable charges a flat fee of $200/month.
For enterprise requirements and SLAs, contact sales.
300+ connectors for hard-to-find data sources other ETL tools don't support.
Development and maintenance of custom connectors at no additional cost and with fast turnaround times.
Premium support for users on all plans.
Portable doesn't have connectors for major enterprise applications like Oracle, Salesforce, or Quickbooks.
Does not support data lakes.
Only available for customers in the U.S.
Portable is best for teams with long-tail data sources that want to focus on insights, not data management.
Dataflow is an ETL tool that's part of the Google Cloud Platform. It accepts pipelines built in Java or Python and integrates seamlessly with BigQuery. Dataflow uses Apache Beam as its engine.

Dataflow is best suited for teams fully integrated into the Google Cloud ecosystem that are looking for a code-first ETL tool.
Google Cloud Data Fusion is another GCP product, but one focused more on simple integrations than complex data transformation workflows.
Data Fusion is a no-code platform that uses a GUI to import data into BigQuery. It's built with the open-source Cask Data Application Platform (CDAP) under the hood.

Nearly every data integration tool has at least some level of integration with BigQuery. Here are some other tools that weren't featured but may be good fits for your organization's needs.
Spark is an open-source engine for processing large amounts of data. It works with both batch and streaming data, and recognizes Java, Python, R, Scala, and SQL languages.
