 {{esql}} is built on top of a new compute architecture within {{es}}, designed to achieve high functional and performance requirements for {{esql}}. {{esql}} search, aggregation, and transformation functions are directly executed within Elasticsearch itself. Query expressions are not transpiled to Query DSL for execution. This approach allows {{esql}} to be extremely performant and versatile.
 
 The new {{esql}} execution engine was designed with performance in mind — it operates on blocks at a time instead of per row, targets vectorization and cache locality, and embraces specialization and multi-threading. It is a separate component from the existing Elasticsearch aggregation framework with different performance characteristics.
