The Apache Kudu team is happy to announce the release of Kudu 1.18.0! Kudu is an open source storage engine for structured data which supports low-latency random access together with efficient analytical access patterns. It is designed within the context of the Apache Hadoop ecosystem and supports many integrations with other data analytics projects both inside and outside of the Apache Software Foundation.
The new release adds several new features and improvements, including the following: - Segmented LRU Block Cache (Experimental): Helps protect hot data from eviction during large scans. - Embedded RocksDB for Metadata (Experimental): A new option to store metadata in embedded RocksDB for better scalability. - Auto-Incrementing Columns Enhancements: These columns are now correctly restored on backup/restore and initialized on bootstrap. - Improved Metrics & Observability: Added metrics for timeouts, tablet scans, RPC backlogs, and more as well as Prometheus support for tablet-level metrics. - Build and Platform Updates: Kudu now supports AArch64 Ubuntu/RedHat, Ubuntu24.04 and builds on macOS Sonoma (Xcode 15). - Java & Python Client Improvements: -- Python: simplified installation, UPSERT IGNORE, soft-deletes, immutable columns -- Java: configurable buffer size, better schema update handling - Security Enhancements: -- Improvements in JWT authentication -- Dedicated SPNEGO keytab for embedded webserver -- HTTP headers for enhanced security of the embedded webserver - Kudu CLI & Tooling Improvements: Better error messages and handling in kudu table copy, scan, and others.
