This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Currently, Opensearch returns a 200 OK response code for a Bulk API call, even though there can be partial/complete failures within the request E2E. Tracking these failures requires client to parse the response on their side and make sense of them. But, a general idea around trend in growth of different rest status codes at item level can provide insights on how indexing engine is performing. Signed-off-by: Rohit Ashiwal <rashiwal@amazon.com>
