Hello. We already have debezium to CDC from different datasources (mysql, postgres, mssql,...) Can we reuse kafka schema-registry or

dbhistory

topics for datahub?

Hi @mysterious-monkey-71931: yes you can reuse the same kafka schema-registry for datahub as well. Was that your question?

@mammoth-bear-12532 I mean can I ingest metadata from kafka schema-registry or

dbhistory

topics to datahub instead direct access to datasources?

@mysterious-monkey-71931 that’s an interesting idea. I guess it could be done. Technically you are inferring the schema of the upstream table by looking at the replication system.

@mammoth-bear-12532,

schema-registry

is store full table schema in format of Avro, Protobuf or JSONSchema. The datatype will not exact match in db (because of conversion), but it's acceptable.

dbhistory

 topics store DDL change log, e.g

CREATE TABLE

or

ALTER TABLE
