5. AppPatchUpdateCheckpointDeltaRequest

PatchUpdateCheckpointDeltaRequest defines the body of a request to the bandwidth-optimized version of the patch update checkpoint endpoint of the service API. It is semantically equivalent to the PatchUpdateCheckpointRequest, but instead of transferring the entire Deployment as a JSON blob, it encodes it as a textual diff against the last-saved deployment. This conserves bandwidth on large resources.

Properties

• version integer required
  Protocol version.
• checkpointHash string required
  SHA256 hash of the result of aplying the DeploymentDelta to the previously saved deployment.
• sequenceNumber integer required
  Idempotency key incremented by the client on every PATCH call within the same update.
• deploymentDelta object optional
  Textual diff that recovers the desired deployment JSON when applied to the previously saved deployment JSON.
