Hi guys, in which format datahub stores info in kafka? Avro or json?

datahub uses both json and avro format , most of them being in avro . Below are the name of topics and their format to give you an idea • MetadataChangeProposal_v1 - avro • FailedMetadataChangeProposal_v1 - avro • MetadataChangeLog_Versioned_v1 - avro • MetadataChangeLog_Timeseries_v1 - avro • DataHubUsageEvent_v1 - json

Thank you :)

schema-registry contain schema to define schema/data structure for messages/record in topic for different data format like json/avro . it is used by application (kafka producer/consumer) to read/message from topics

Thanks a lot
