These enhancements are designed to streamline the workflow of data scientists, engineers, and analysts, making Databricks an even more powerful tool for data-driven insights and analysis.

2. Announcing the General Availability of Predictive Optimization

Databricks also announced the General Availability of its new Predictive Optimization feature. This feature automates data layout optimization to enhance query performance and reduce storage costs.

Key Features and Benefits:

Automated Data Layout Optimization: Predictive Optimization leverages AI to analyze query patterns and determine the best optimizations for data layouts. This automation reduces the need for manual maintenance and improves performance and cost efficiency. The feature eliminates the need for data teams to manually manage maintenance operations, such as scheduling jobs, diagnosing failures, and managing infrastructure.Intelligent Analysis: The AI model behind Predictive Optimization evaluates various factors, including data layout, table properties, and performance characteristics, to decide the most impactful optimizations. This intelligent analysis ensures that optimizations are tailored to the organization’s needs, leading to immediate and substantial benefits.
For example, the energy company Plenitude experienced a 26% reduction in storage costs shortly after enabling Predictive Optimization. This capability allowed them to retire manual maintenance procedures and achieve greater scalability.
Adaptive Learning: Predictive Optimization continuously learns from the organization’s data usage patterns, adjusting optimizations based on these patterns to ensure efficient data storage and ongoing performance improvements. The intelligence engine learns from your organization’s usage over time, ensuring that your data is always stored in the most efficient layout, translating to cost savings and performance gains without continuous manual intervention.
Toloka AI, an AI data annotation platform, replaced their DIY table maintenance solution with Predictive Optimization, which proved more efficient and cost-effective.
Automatic Liquid Clustering: A new feature since the Preview, Predictive Optimization now automatically runs OPTIMIZE on tables with Liquid Clustering and performs vacuum and compaction operations. This automation ensures that clustering occurs at an optimal cadence for better query performance.Impact in Numbers: Since its Preview launch, Predictive Optimization has been implemented across hundreds of thousands of tables, optimizing exabytes of data. These optimizations have significantly improved query performance by optimizing file size and layout on disk, generating millions in annual storage savings for customers.
Anker: The data engineering team at Anker reported a 2x improvement in query performance and 50% savings in storage costs after enabling Predictive Optimization. The AI model prioritized their largest and most-accessed tables, delivering these benefits automatically.

Customer testimonials highlight the practical benefits of Predictive Optimization. Users report significant improvements in query performance and storage cost savings.

Future Enhancements:

Databricks plans to continue enhancing Predictive Optimization. Upcoming features include:

Built-in Observability Dashboard: This dashboard will provide insights into the optimizations performed and their impact on query performance and storage savings, making the benefits transparent and measurable.Automatic Statistics Collection: Predictive Optimization will soon collect statistics during supported write operations and intelligently update these statistics in the background, ensuring query plans are optimized efficiently. These background operations are run as necessary and determined by smart logic that tracks when statistics are stale, and the workload needs them.

Soon, Predictive Optimization will be enabled by default across all Unity Catalog-managed tables, providing optimized data layouts and efficient storage without any manual intervention.

Organizations can start using Predictive Optimization by enabling it in the account console. This feature represents a significant step in automating data optimization and maintenance, allowing data teams to focus more on driving business value rather than managing infrastructure.

3. Introducing Databricks LakeFlow: A Unified, Intelligent Solution for Data Engineering

The third major announcement is the introduction of Databricks LakeFlow, a comprehensive solution designed to streamline and enhance the process of building and operating production data pipelines.
