      Description

      In certain situations (using EBS snapshot + large oplog), oplog sampling can take significantly longer because of data being loaded from S3 in AWS.

      While this is due to AWS behaviour, it would be great to highlight in our docs the way an EBS snapshot will perform before being warm up and how this can affect the oplog sampling part of the mongod startup.

      Scope of changes

      • This will likely need a section in the Production Notes, and possibly in our backup/restore docs

        Impact to Other Docs

      • Possible impact to ops/cloud manager snapshots on S3 buckets?
