JIT for the Code Vectorization Can't Optimize

MLIR is a general-purpose framework for building compilers — it bridges high-level code and low-level machine code, giving DolphinDB a much more flexible foundation for optimization.But the more interesting question isn’t what’s new under the hood. It’s this: DolphinDB already has strong vectorized computing.
