Labels: pull-request-available stale-major (was: pull-request-available)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 60 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Dedicated Opensearch connectors
> -------------------------------
>
> Key: FLINK-25756
> URL: https://issues.apache.org/jira/browse/FLINK-25756
> Project: Flink
> Issue Type: New Feature
> Components: Connectors / Common
> Reporter: Andriy Redko
> Priority: Major
> Labels: pull-request-available, stale-major
>
> Since the time Opensearch got forked from Elasticsearch a few things got
> changed. The projects evolve in different directions, the Elasticsearch
> clients up to 7.13.x were able to connect to Opensearch clusters, but since
> 7.14 - not anymore [1] (Elastic continues to harden their clients to connect
> to Elasticsearch clusters only).
> For example, running current Flink master against Opensearch clusters using
> Elalsticsearch 7 connectors would fail with:
>
> {noformat}
> Caused by: ElasticsearchException[Elasticsearch version 6 or more is
> required]

> Arguably, the best way to proceed in this situation is to provide dedicated
> Opensearch connectors, on par with Elasticsearch ones.
> Me ([~reta]) and [~Sergey Nuyanzin] would be more than happy to make the
> contribution (and maintain it as well), if there are no objections from
> committers / PMC members.
