s: adapter input schema</h2><p>Mixer is typically invoked twice for every incoming request to a mesh service, once for precondition checks and once for telemetry reporting. For every such call, Mixer invokes one or more adapters. Different adapters need different pieces of data as input in order to do their work. A logging adapter needs a log entry, a metric adapter needs a metric, an authorization adapter needs credentials, etc.
