Rebalancing and routing are done automatically". Each node hosts one or more shards and acts as a coordinator to delegate operations to the correct shard(s). "Elasticsearch is distributed, which means that indices can be divided into shards and each shard can have zero or more replicas. It provides scalable search, has near real-time search, and supports multitenancy. Features Įlasticsearch can be used to search any kind of document. Due to potential trademark issues with using the name "Elasticsearch", AWS rebranded their fork as OpenSearch in April 2021. Other users of the ElasticSearch ecosystem, including Logz.io, CrateDB and Aiven, also committed to the need for a fork, leading to a discussion of how to coordinate the open source efforts. Amazon responded with plans to fork the projects and continue development under Apache License 2.0. Critics of the re-licensing decision predicted that it would harm Elastic's ecosystem and noted that Elastic had previously promised to "never.change the license of the Apache 2.0 code of Elasticsearch, Kibana, Beats, and Logstash". Elastic blamed Amazon Web Services (AWS) for this change, objecting to AWS offering Elasticsearch and Kibana as a service directly to consumers and claiming that AWS was not appropriately collaborating with Elastic. In January 2021, Elastic announced that starting with version 7.11, they would be relicensing their Apache 2.0 licensed code in Elasticsearch and Kibana to be dual licensed under Server Side Public License and the Elastic License, neither of which is recognized as an open-source license.

Įlastic NV was founded in 2012 to provide commercial services and products around Elasticsearch and related software. Shay Banon released the first version of Elasticsearch in February 2010. So he created "a solution built from the ground up to be distributed" and used a common interface, JSON over HTTP, suitable for programming languages other than Java as well. While thinking about the third version of Compass he realized that it would be necessary to rewrite big parts of Compass to "create a scalable search solution". Shay Banon created the precursor to Elasticsearch, called Compass, in 2004. According to the DB-Engines ranking, Elasticsearch is the most popular enterprise search engine. NET ( C#), PHP, Python, Ruby and many other languages. Elasticsearch is developed in Java and is dual-licensed under the source-available Server Side Public License and the Elastic license, while other parts fall under the proprietary ( source-available) Elastic License. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents.
