Elasticsearch 5 overview

Elasticsearch 5 will follow Elasticsearch 2 as the next major software release. Although this may be chronologically jarring, Elastic.co purposefully jumped from version 2 to 5 to better synchronize the updated version of Elasticsearch with several other Elastic.co products, including Kibana, Logstash, Marvel (called Monitoring in 5.0), and more. This update will help ensure that all Elastic.co software running on a cluster is both compatible and up-to-date.

There are hundreds of new changes being introduced in version 5, but a few relevant highlights include:

• Compatibility between the Elasticsearch 2 API and Elasticsearch 5

• Indices from Elasticsearch 2 can be migrated to version 5:

  • Indices from Elasticsearch 1 must first be migrated to version 2 before migrating them to version 5

• Marvel is renamed Monitoring

• The Elasticsearch-Logstash-Kibana stack is renamed the Elastic Stack

• The plugin API no longer supports site plugins, including plugins such as Elasticsearch-head...
