Protobuf Goes Scala-First
summary
Claims a Scala-first workflow that generates protobuf from Scala types, using ZIO Blocks Schema to derive codecs and producing Protobuf files plus encoders/decoders and gRPC bindings. Implements Protist, open sourced, runs in production 5 months, handles a codebase with ~5,600 messages and 94 services, migrates two of three APIs so far, and yields about a 25% compile time reduction while keeping runtime encoding close to ScalaPB+Chimney and allocating less memory.
