Free enterprise search with OpenSearch
summary
OpenSearch is a fork of Elasticsearch 7.10 developed mainly by Amazon and shipping as version 2.9.0, with plugins (cluster restart, process-bound) and new extensions (separate processes). Core claims: many paid Elasticsearch enterprise features are reimplemented and run as plugins, some features (cross‑cluster replication) remain AWS‑bound, and official support is only via Amazon. Migration for typical Java apps is mostly mechanical: change dependencies, replace imports, use OpenSearch CA fingerprint, while complex setups using newer Elasticsearch features or third‑party plugins may require significant rewrites.
