Registering Data Sources in SSB
Data Sources are a set of data endpoints to be used as sources, sinks and catalogs. Data Sources allow you to connect to an already installed component on your cluster, then use that provider for adding tables in SQL Stream Builder (SSB).
You can register Kafka as a data source, or Kudu, Hive and Schema Registry as a catalog and you can also add custom catalogs. When registering the components, SSB can access the already existing topics from Kafka, tables from Kudu and Hive, and the schema in Schema Registry. This also means that when you update a data source, for example add new topics, tables and schemas, SSB automatically detects the changes.
