Does Magento 2.4.4 run on OpenSearch 2.19.5?
NoNone of the 14 Magento 2.4.4 releases we tested install on OpenSearch 2.19.5. This release indexes through mapping-type endpoints that the search engine has removed, so installs succeed but saving a product fails. The newest Magento release that installs on OpenSearch 2.19.5 is 2.4.9. Our 2.4.4-p13 baseline uses Elasticsearch 7.16.3, one of the versions Adobe lists.
Last run 2 October 2026. Each run is our baseline stack for the release, picked from Adobe's system requirements, with only the search swapped for OpenSearch 2.19.5, installed in Docker, compiled and put through storefront, checkout and admin browser tests.
