Modeling Guide for SAP Data Hub

Record Ingest via Disk

The data generator generates a series of messages, each consisting of one or more record objects. Each message is directly passed to the ingestor, which stores the records in the vora disk engine and emits the commit token associated with each message.

The table definition is not provided as an avro schema but instead included in the message at attribute key vora.record.definition.
