Dive Deep on OpenSearch’s Vector Search - Jon Handler & Yuye Zhu, Amazon Web Services

Wednesday April 30, 2025 11:15 - 11:55 CEST

Matterhorn

Search engines take in a query and return a set of results that best satisfy the need of the searcher. Words from a text box, user interface facets, and some user identity information have been the clues for good retrieval. Today, Large Language Models (LLMs) produce vectors with semantic information that augments or replaces lexical information for retrieving best results. OpenSearch's low-level APIs can connect with and use LLMs as part of an overall search solution. A full solution still requires some higher-level coding to take full advantage of these APIs. In this talk, we’ll cover some theory on similarity, and how and where vectors can help you retrieve better results. We’ll dive deep on opensearch-ml-quickstart (https://github.com/Jon-AtAWS/opensearch-ml-quickstart), an open-source example set for managing connections with OpenSearch, local models, and vector embeddings. We’ll walk through examples and code to help you get started quickly with OpenSearch’s vector capabilities: exact nearest-neighbor matching, dense vector embeddings, and sparse vectors. You’ll leave with a great tool in opensearch-ml-quickstart, along with the knowledge of how to apply it.

From Zero To Maintainer: How We Implement Generation of Code for 4 Clients (JS, Ruby, Python, Java) - Torekeldi Niyazbek, DEMETRA SYSTEMS

Wednesday April 30, 2025 11:35 - 11:55 CEST

Zurich II

As a Maintainer of the OpenSearch Specification Repository, I’d like to share how we addressed a major challenge in maintaining OpenSearch clients (Ruby, Python, Java, Node.js).

Every OpenSearch update required manual replication of changes across all clients, consuming countless hours since version 1.0. By version 2.18, it became clear we needed a scalable solution. Our team built a Specification Repository that centralizes all possible request and response schemas, enabling automated client code generation.

We use OpenAPI specifications and a custom testing framework to ensure consistency, minimize human error, and accelerate development. This approach eliminates repetitive work, improves reliability, and scales better with OpenSearch's growth.

I will demonstrate how the repository works, share code generation examples, and discuss its impact on reducing maintenance overhead while improving client reliability. Additional resources showcasing real-world applications will be provided.

This solution not only streamlines client updates but also sets a foundation for innovation in OpenSearch's ecosystem.

Enhancing Application Observability With OpenSearch and OpenTelemetry - Karsten Schnitter, SAP SE

Wednesday April 30, 2025 14:30 - 15:10 CEST

Matterhorn

How do you know whether your applications are running smoothly or struggling? OpenSearch can provide insights and analyze telemetry data of your applications. Modern observability revolves around three core signal types: logs, metrics, and traces. This talk demonstrates how to instrument your applications and collect these signals using OpenTelemetry, enabling comprehensive insights into application performance and health.
We explain how to map the data in a way to easily correlate logs, metrics, and traces. Building on these correlations we present how OpenSearch can be leveraged to generate advanced insights. Explore with us how far this correlated approach can exceed solutions focussing on just logs or traces.
We'll start by exploring how to process and index telemetry data with Data Prepper, making it ready for analysis, dashboarding, and alerting within OpenSearch.
You’ll learn effective strategies to map and correlate logs, metrics, and traces, unlocking deeper relationships between these signals.
Building on these correlations, we’ll showcase how OpenSearch can deliver advanced insights, enabling you to diagnose problems faster and make informed decisions.

A Tool for Eyeballing: Better Than NDCG? - Stavros Macrakis, OpenSearch @ AWS & Eric Pugh, OpenSource Connections

Wednesday April 30, 2025 14:30 - 15:10 CEST

Zurich I

There are lots of statistics we can calculate for search relevance: NDCG, precision, MAP, …. OpenSearch 3.0 calculates and displays them for you.

But metrics don’t tell the whole story. In particular, NDCG can’t give you the qualitative analysis that one algorithm is great for author names, and a different one is good for shapes and sizes. For that, you need eyeballing, that is, human intuition and judgment.

That’s why we’ve built tools to help you dig deeper into your search results. The Search Comparison tool in OpenSearch 2.11 is just the starting point – in 3.0, it lets you define search configurations and test sets of multiple queries and determine which queries’ results have changed the most… and then zoom in to the individual cases. You can integrate data on judgments and query frequency from User Behavior Insights for deeper analysis.

In this talk, we’ll discuss how traditional statistical metrics are complemented by eyeballing, how the new tools in OpenSearch 3.0 support disciplined eyeballing, and how you can use them to improve the quality of your search results.

Data Prepper or Logstash: Helping You Choose Your Ingestion - David Venable & Krishna Kondaka, Amazon Web Services

Wednesday April 30, 2025 15:15 - 15:35 CEST

Matterhorn

OpenSearch Data Prepper is a pipeline tool within the OpenSearch project for data ingestion. A common question that comes up within the open-source community is how it relates to Logstash. While both tools are open-source and designed to collect, transform, and route data from various sources to destinations, they differ significantly in their features and target use cases.

Logstash, a mature platform with a vast plugin ecosystem, provides flexible and extensive customization options. Data Prepper is a newer offering initially designed for modern observability needs, such as handling OpenTelemetry (OTel) logs, traces, and metrics. Over time, it has evolved into a general-purpose tool capable of interfacing with numerous open-source and proprietary solutions.

In this presentation, we will explore the architectural differences between Data Prepper and Logstash. We’ll also conduct a comparison of their core features, emphasizing Data Prepper's unique capabilities that enable integration with tools such as OpenTelemetry, OpenSearch, Kafka, S3, DynamoDB, and Kinesis. Finally, we'll provide practical guidance and examples to facilitate a smooth migration from Logstash to Data Prepper.

Using OpenSearch With OpenTelemetry To Solve Real World Scenarios - Shambhavi Sarin, Salesforce & Abhay Baiju, Atlassian

Wednesday April 30, 2025 15:50 - 16:30 CEST

Matterhorn

In this presentation, we’ll go over a real world scenario where we used OpenTelemetry to collect data from logs, metrics and traces and OpenSearch to store and search them. We were involved in the migration to OpenSearch in a food delivery company with close to a million orders a day. To observe the performance of its microservices, a large amount of data was collected and monitored in real time on dashboards.

In the checkout flow from adding an item in the cart to placing an order, several teams were involved. They had their own microservices and dashboards to observe them. So to trace any bug, the teams were relying on an internal order id. This id was not part of the contract of all services and thus made it hard to debug.

Here’s when we introduced distributed tracing using context across all microservices. We migrated to OpenTelemetry and OpenSearch and made changes in the logs, metrics and traces of all services across teams. This made it easier to search logs and look for issues effectively. In this discussion, we’ll discuss this scenario and the challenges we faced as part of implementing it. We will also discuss the benefits of this approach we observed afterwards.
