AI models, whether for machine learning or deep learning, require vast amounts of data to train, validate, and test. But not just any data will do—this data must be accessible, scalable, and optimized for efficient processing. This is where the concept of "AI-ready data" comes into play.
"AI-ready data" refers to data that meets specific criteria to support the demands of AI development: it must be accessible for easy access, scalable for large volumes, and governed to ensure compliance. Ensuring data meets these criteria can be challenging, especially with the complexity of modern data landscapes that include data lakes, databases, warehouses, and more.
Let's explore the critical roles Dremio and Apache Iceberg play in making data AI-ready. By leveraging these tools, data teams can prepare, manage, and optimize structured data to meet the demands of AI workloads, helping organizations scale their AI development efficiently.
What is AI-Ready Data?
For data to be truly AI-ready, it must meet several key requirements. Here’s a look at the core attributes of AI-ready data and why each is essential in AI development:
Accessibility: Data should be accessible from various environments and applications. AI models often rely on multiple data sources, and having data that’s readily accessible without extensive ETL (Extract, Transform, Load) processes saves time and resources.
Scalability: AI workloads are typically data-intensive. To scale, data must be stored in formats that allow for efficient retrieval and processing at scale, without performance bottlenecks.
Transformability: AI models often require data in a particular structure or with certain attributes. AI-ready data should support complex transformations to fit the needs of different models, whether it’s feature engineering, data normalization, or other preprocessing steps.
Governance: Ensuring compliance is crucial, especially when working with sensitive data. Governance controls, such as access rules and audit trails, ensure that data usage aligns with privacy policies and regulatory requirements. Governance is also important for model accuracy—making sure the model isn’t trained on irrelevant or unauthorized data.
Preparing data that meets these criteria can be difficult, particularly when handling vast amounts of structured and unstructured data across multiple systems. However, with tools like Apache Iceberg and Dremio, data teams can address these challenges and streamline structured data preparation for AI workloads.
How Apache Iceberg Enables AI-Ready Structured Data
Apache Iceberg is a powerful open table format designed for large-scale, structured data in data lakes. Its unique capabilities help make data AI-ready by ensuring accessibility, scalability, and flexibility in data management. Here’s how Iceberg supports the requirements of AI-ready data:
Accessible, Transformable Data at Scale: Apache Iceberg enables large-scale structured data to be easily accessed and transformed within data lakes, ensuring that data can be queried and modified without the complexities typically associated with data lake storage. Iceberg’s robust schema evolution and versioning features allow data to stay accessible and flexible, accommodating changing requirements for AI models.
Historical Data Benchmarking with Time Travel: Iceberg’s time-travel functionality allows data teams to query historical versions of data, making it possible to benchmark models against different points in time. This is invaluable for training models on data snapshots from various periods, allowing comparison and validation with past data states.
Partition Evolution for Data Optimization: Iceberg’s partition evolution feature enables experimentation with partitioning strategies, helping data teams optimize how data is organized and retrieved. Optimized partitioning allows for faster data access and retrieval, which can reduce model training time and improve overall efficiency.
With these features, Apache Iceberg helps maintain structured data that’s accessible, transformable, and optimized, creating a robust foundation for AI workloads in data lakes.
How Dremio Empowers AI-Ready Data Management
Dremio provides a unified data platform that enhances the management and accessibility of data, making it an ideal tool for preparing AI-ready data. Here are some of the ways Dremio’s features support AI development:
First-Class Support for Apache Iceberg: Dremio integrates seamlessly with Apache Iceberg, allowing users to manage and query Iceberg tables without complex configurations. This makes it easier for data teams to leverage Iceberg’s capabilities directly within Dremio.
