The introduction of OTel instrumentation in SpiceDB allows for better visualization and understanding of how SpiceDB walks the graph, representing the schema. This enables developers to visualize the sequence of steps taken to respond to an API request, providing insights into the consistency model and tunable settings such as minimize_latency, which offers a good compromise between performance and security. The OTel instrumentation provides detailed traces of requests, including sub-problems being computed, dispatching, and querying the database, enabling developers to better understand the underlying logic of SpiceDB's authorization system.
