What is Amazon OpenSearch Service? OpenSearch is a distributed, open-source search and analytics package that may be used for real- time application monitoring, log analysis, and internet search, among other things. With OpenSearch Dashboards, an integrated visualization tool that makes it easy for users to examine their data, OpenSearch provides a highly scalable solution for quick access and reaction to massive amounts of data. The Apache Lucene search library, as well as OpenSearch, Elasticsearch, and Apache Solr, support it. Elasticsearch 7.10.2 and Kibana 7.10.2 were used to create OpenSearch and OpenSearch Dashboards. The Apache License Version 2.0 applies to all software in the OpenSearch project (ALv2).
