The switch reduced compute launch time from 8 to 2 minutes and significantly lowered infrastructure costs. Polars' streaming engine enables processing datasets larger than available memory on modest hardware. The team now uses Polars for new pipelines with stable, smaller input tables that don't require complex joins or aggregations, while keeping Spark for terabyte-scale workloads. Challenges include managing Kubernetes infrastructure and limitations with certain Delta Lake features. 70 2. 2 [](https://daily.dev/posts/cloudflare-open-sources-tokio-quiche-promising-easier-quic-and-http-3-in-rust-hgsdjizbn "Cloudflare Open Sources tokio‑quiche, Promising Easier QUIC and HTTP/3 in Rust") Article InfoQ · 37w Cloudflare Open Sources tokio‑quiche, Promising Easier QUIC and HTTP/3 in Rust Cloudflare released tokio-quiche, an open-source Rust library that wraps their quiche QUIC/HTTP/3 implementation with Tokio's async runtime. The library simplifies building high-performance QUIC applications by handling UDP I/O, connection management, and event loops automatically. It uses an actor model internally and exposes an ApplicationOverQuic trait for protocol abstraction. Cloudflare uses it in production for edge services, HTTP proxies, and MASQUE-based tunnels in their WARP client, handling millions of requests per second. The library is available on crates.io as a foundational building block, with plans to release higher-level HTTP client/server abstractions. 34 1 3. 3 [](https://daily.dev/posts/java-news-roundup-spring-tools-5-tornadovm-payara-platform-hibernate-orm-spock-framework-13nslxxje "Java News Roundup: Spring Tools 5, TornadoVM, Payara Platform, Hibernate ORM, Spock Framework") Article InfoQ · 38w Java News Roundup: Spring Tools 5, TornadoVM, Payara Platform, Hibernate ORM, Spock Framework JDK 26 Build 28 and JDK 27 Build 2 early-access builds are now available with various bug fixes.
