AWS Certified Data Analytics Specialty 2021 – Hands-On - Introduction to OpenSearch (formerly Elasticsearch)

Open Search, a fork of Elasticsearch, is a scalable search engine and analysis tool. It originated from a licensing dispute between Amazon and Elastic, leading to Amazon's creation of Open Search. Built on Lucene, it supports JSON requests for indexing and searching documents. Open Search has evolved to include visualization tools like Dashboards, formerly Kibana, and is used for various applications such as log analytics, application monitoring, and security analytics. It offers horizontal scaling through shards and supports data ingestion via Kinesis, making it a versatile tool for handling large-scale data.
