// uncomment this to test against the fix
//replace cloud.google.com/go/datastore v1.17.1 => github.com/pendo-io/google-cloud-go/datastore v1.0.1-0.20240829131339-abf77c09d0ae

Expected behavior

When running the sample code, I'd expect that the transactions would fail fast as only one attempt is being set. The test code should run in < 2s.

Note: to see the results with the patched code, uncomment the replace line in the provided go.mod file, run go mod tidy and go build`.

Additional context

This appears to be directly related due to the change made in #10349, which was released in datastore/v1.17.1. In my opinion, this is a pretty big change for a patch release, even if it is marked as a bugfix.
