  Splunk ships two generations of client libraries for Splunk Observability Cloud and they
  must not be read as one shelf. The SignalFx-era metric/ingest libraries (signalfx on PyPI
  and npm, com.signalfx.public on Maven) are DEPRECATED and their repositories say so; the
  current first-party path is the Splunk Distributions of OpenTelemetry plus the SignalFlow
  clients. The control-plane REST API described in openapi/ has no dedicated generated SDK —
  signalfx-go is the closest thing and is the library the Terraform provider is built on.
