In today’s data-driven world, the ability to efficiently transform raw data into actionable insights is paramount. However, data preparation and cleaning is often a significant challenge. According to Gartner®1 “Gartner clients now report that 90% or more of their time is spent preparing data (as high as 94% in complex industries) for advanced analytics, data science and data engineering.
Reducing this time and efficiently transforming raw data into insights is crucial for staying competitive. Earlier this month, Google Cloud introduced BigQuery data preparation, an AI-first solution that streamlines and simplifies the data preparation process as part of Gemini in BigQuery.
Now in preview, BigQuery data preparation provides a number of capabilities:
- AI-powered suggestions: BigQuery data preparation uses Gemini in BigQuery to analyze your data and schema and provide intelligent suggestions for cleaning, transforming, and enriching the data. This significantly reduces the time and effort required for manual data preparation tasks.
- Data cleansing and standardization: Easily identify and rectify inconsistencies, missing values, and formatting errors in your data.
- Visual data pipelines: The intuitive, low-code visual interface helps both technical and non-technical users easily design complex data pipelines, and leverage BigQuery’s rich and extensible SQL capabilities.
- Data pipeline orchestration: Automate the execution and monitoring of your data pipelines. The SQL generated by BigQuery data preparation can become part of a Dataform data engineering pipeline that you can deploy and orchestrate with CI/CD, for a shared development experience.
BigQuery data preparation helps you ensure the accuracy and reliability of your data, leading to more informed business decisions. BigQuery data preparation automates data quality checks and integrates with other Google Cloud services such as Dataform and Cloud Storage, providing a unified and scalable environment for your data needs.
How does it work?
Getting started is easy. When you sample a BigQuery table in BigQuery data preparation, it uses state-of-the-art foundation models to evaluate the data and schema using Gemini in BigQuery to generate data preparation recommendations like filter and transformation suggestions. For example, it knows how to identify valid date formats by country and which columns can act as join keys, accelerating the data engineering process.
In the above example (using synthetic data), the Birthdate column contains two different date formats and is of type STRING. BigQuery data preparation suggests to “Convert column Birthdate from type string to date with the following format(s): ‘%Y-%m-%d’,’%m/%d/%Y”. After you apply the suggestion card, you can verify the transformed preview data in a DATE format column.
With BigQuery’s AI-assisted data preparation, you can:
- Significantly reduce time spent discovering data quality issues and cleaning data by leveraging Gemini-assisted suggestion cards
- Customize your own suggestion cards by providing an example in the data grid
- Increase operational efficiency by deploying data preparation with incremental data processing
