The Event-Driven model heavily relies on the QUALITY of events. Good quality events are: explicitly defined via contracts have comments support evolution with backward and forward compatibility support code generation breaking changes are well thought Good events are implemented using the right tools: use Avro/Thrift/Protobuf formats and never use JSON! use the right event broker (such as Pulsar) Good events are designed to: contain all the info needed by consumers use separate streams for each event type use the right data types for their fields (don’t use string for numbers, use enums, etc.
