Since the 1970s, SQL has been the lingua franca for databases. However, for specialized databases, it might not make sense to expose such a general-purpose API. SpiceDB is one such database that chose gRPC its primary query interface. This presentation will walk through our journey selecting gRPC, lessons learned modeling our APIs, how we maintain clients in all popular languages, what tools we recommend or have built ourselves, and the optimizations we've made to our codebases to make gRPC a success.
