Introducing Apache Druid® 32.0

Apache Druid 32.0 introduces significant enhancements for real-time analytics, focusing on stability, performance, and advancing experimental features. A major highlight is the introduction of Distributed Embedded Projection, which improves query performance by pre-computing aggregations while maintaining data consistency, effectively flattening latency curves for large datasets. The release also expands support for AWS Glue catalog with Iceberg table format, facilitates better Deltalake integration with improved column selection and snapshot access, and introduces join hints to optimize SQL-based ingestion queries. UI enhancements in the Explore view improve data visualization, while the new segment timeline view aids in managing data distribution. Additional features include automatic number guessing for CSV/TSV ingestion, gRPC/protobuf support for efficient SQL queries, and official support for the ZGC garbage collector to reduce latency in high-concurrency scenarios. For further exploration, users can access Druid 32.0 through Imply Polaris or various community resources.
