Execution in a Vectorized Query Engine
ES\|QL is a new piped query language for Elasticsearch. It supports writing composable queries and it features a multi-staged execution. Unlike the other languages supported by Elasticsearch\, ES\|QL doesn't transpile to Query DSL or use the internal search client: it's based on its own stack. This comes with a sophisticated query analysis and optimisation steps\, as well as parallelisation and vectorisation. This talk will give an overview of the execution flow of a query and touch on a few key implementation aspects\, following the query from its first syntactic analysis down to Lucene delegation followed by returning the results back to the user\, all in a distributed environment.

Open source observability with OpenTelemetry and Elasticsearch
Recognized by Gartner as a leading observability tool, Elasticsearch is not just log analytics. It has infrastructure monitoring, alerts, APM capabilities - and it's all open-source!
Now with the addition of OpenTelemetry, it's even easier to onboard your telemetry data in a standard and vendor-neutral way.
Join Andrzej in a technical session to discover the shortest path from zero to a fully functional open-source observability solution with the OTEK stack - OpenTelemetry, Elasticsearch and Kibana.
Andrzej Stencel - (Senior Software Engineer @ Elastic)
Evaluating Elasticsearch Nearest Neighbour Search for E-Commerce
Experiments to analyze the utility, efficiency and effectiveness of brute force k nearest neighbor and approximate nearest neighbor algorithms available in Elasticsearch to enable Zalando's search, browse and fashion assistant capabilities.
