YMatrix mxvector: How to implement high performance pluggable vectorized executor in PostgreSQL
PostgreSQL's performance in OLAP and HTAP scenarios can be significantly enhanced through a vectorized executor, an optimized execution model tailored for analytical workloads. By leveraging typed operations, batched processing, and SIMD instructions, vectorized execution minimizes overheads associated with traditional row-by-row processing, such as repeated function calls and data extraction f...
