Hi @JM-Lab, AWS also provides OpenSearch and the java sdk provides AwsSdk2Transport. Wonder if should be part of this PR or a separate one.

Hi @eddumelendez,

Sure, use AwsSdk2Transport for OpenSearchClient. Check this link for details: https://opensearch.org/docs/latest/clients/java/#connecting-to-amazon-opensearch-service

Hi @tzolov,

I plan to address your requests within the next 1-2 weeks. Would you prefer me to add commits to the current pull request or handle them in a separate pull request? Let me know what you think.

Hi @tzolov,

Will reset tangled commits and soon add documentation for vectordbs with updates to catalog nav.adoc for a clean pull request.

I've just created a new PR focusing solely on the OpenSearch files, on the main branch. You can find it here: https://github.com/spring-projects/spring-ai/pull/663.

Going to close this current one. Thanks!
