ES|QL's compute architecture ES|QL is built on top of a new compute architecture within Elasticsearch, designed to achieve high functional and performance requirements for ES|QL. ES|QL search, aggregation, and transformation functions are directly executed within Elasticsearch itself. Query expressions are not transpiled to Query DSL for execution. This approach allows ES|QL to be extremely performant and versatile. The new ES|QL 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.
