Summary
This chapter examined the upcoming Elasticsearch 5 release, discussed upgrading to version 5, and touched on the new monitoring tools available in the Elasticsearch X-Pack. Some takeaways from this chapter include:
- Elasticsearch 5 has some big performance and reliability gains, but also some breaking changes to the API.
- Elasticsearch-head, Bigdesk, and Kopf are not yet compatible with Elasticsearch 5.
- Elasticsearch 5 is a major release, and upgrading from version 2 may not be a simple process. Be sure to run the Elasticsearch Migration Helper before upgrading.
- The Elasticsearch X-Pack provides a suite of monitoring tools for Elasticsearch 5, but isn't free.
