Is OpenSearch supported in Temporal.io

Hello!

We are planning to use Temporal.io for a small application at my company. Due to licensing restrictions, we don’t want to use ElasticSearch and instead use OpenSearch. However, when connecting our current temporal cluster (as of today 1.24 and not yet upgraded to 1.28) to our OpenSearch cluster, we are getting an error when we try to add custom search attributes.

Is OpenSearch supported as drop-in replacement for ElasticSearch in temporal.io?

Thank you!

Yes we run with opensearch. it works great!

Stick with 2.x version Release v2.19.3
