Validate that OpenSearch is a viable replacement for Elasticsearch for CirrusSearch
Open, MediumPublic


OpenSearch has been published to Github. As far as I can see, there isn't a published distribution yet, but the code to generate .deb seems to be there. We should validate that this fork is usable as a backend for CirrusSearch so that we can start planning a migration.


  • Proof of Concept deployment, potentially running on WMCS and integrated with CirrusSearch
  • decision about moving forward with OpenSearch or not

Event Timeline

OpenSearch was forked from elastic 7.10 but CirrusSearch only supports elastic 6.x so migrating to 7 (T263142) might be necessary before doing this.
