- l is a new runtime for k4, q, and qSQL that maintains syntax compatibility with existing code.
- It executes on a modern engine optimized for compressed vectors, SIMD, and automatic parallelism, reducing data movement.
- Performance benchmarks show significant speedups, such as 3.57x geomean in master suite and 3.16x total query speedup versus DuckDB.
- The runtime transparently selects execution paths (scalar, SIMD, threaded, or offloaded) without requiring code annotations.
- An anonymous mail group is available for technical discussions, benchmarks, and release logs, requiring only email to join.
