The Semantic Search project relies on using the vector search Opensearch capabilities, that are only available as to version 3.
We (DPE SRE) have currently deployed opensearch-k8s-operator 2.7 (along with a custom patch allowing the watching of several k8s namespaces), which is only compatible up to Opensearch 2.19.
| Operator Version | Min Supported Opensearch Version | Max Supported Opensearch Version | Comment |
|---|---|---|---|
| 2.8.0 | 2.19.2 | latest 3.x | Supports the latest OpenSearch 3.x version. |
| 2.7.0<br>2.6.1<br>2.6.0<br>2.5.1<br>2.5.0 | 1.3.x | 2.19.2 | Supports the OpenSearch 2.19.2 version. |
As such, we need to run opensearch-k8s-operator 2.8.0 on our k8s clusters to support Semantic Search.
