AWS revenue. Internal AWS stats. Open search client pulls (not sure if the client is different now). Opensearch is mainly going to be used on AWS so that won't show up as much in GitHub stars.
None of those metrics measure the value of the brand, so none of those metrics are useful for the question that this thread is about: figuring out if AWS benefits from sticking with the OpenSearch brand.
If I'm right that OpenSearch has a weak brand, Amazon could switch and their internal stats and revenue wouldn't budge.
