Protobuf

Protobuf is fairly complex but offers a high-degree of confidence in your event quality due to built-in schema enforcement, type safety and excellent cross-language support.

Pros

• You are tasked with establishing a long-lasting, sophisticated and reliable event-driven architecture at your org

• You MUST have schema-enforcement and type safety

• You need rich type support

• You are (or are planning on) using gRPC

• You want to generate client/server code from schemas

• You want to be able to point folks at good documentation

Cons

• You will have to create your own schema repository and setup a build process to generate your compiled protobufs

• The CLI tools are complex

• Deprecation is less-than-ideal

• Protobuf messages are semi-human-readable - as in, you will not be able to view all values in a message via cat - you will need to properly decode the message

Batch has full support for protobuf - all fields in a protobuf message are indexed and available for search and replay.
