What's in the Workshop Recipe?

In this session you'll learn how to interact with the OpenSearch cluster with the help of OpenSearch NodeJS client - create an index, add documents, search and aggregate data.

At the end we’ll visualise results with OpenSearch Dashboards and sink the data from Apache Kafka.

NodeJS engineers who are ready to add search and aggregation features to their applications should attend this session; no previous knowledge of OpenSearch is required.
