Learn how OpenSearch works and get equipped with practical knowledge to search, aggregate and visualise your data. This is a hands-on session where we will 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. 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.
