Approve, tho this can definitely be reduced in length with a env var in Jenkinsfile.

Suggest improvement later.

Thanks.

@rishabh6788 Can you confirm that SegRep experimental flag opensearch.experimental.feature.segment_replication_experimental.enabled is enabled for this run? Segment Replication integration with remote store is behind this flag.

[rishabh6788]

These are the settings added to nightly remote-store runs.

opensearch.experimental.feature.remote_store.enabled:true 
cluster.remote_store.enabled:true 
opensearch.experimental.feature.segment_replication_experimental.enabled:true. 
cluster.indices.replication.strategy:SEGMENT
