Avro Ingest. via Disk

A series of messages, each consisting of avro records are read from a kafka broker. Each message is passed to the preingestor, which creates a message with record objects. Finally, this message is passed to the ingestor, which stores the records in the vora disk engine and emits the commit token associated with each message.


You need a running SAP Vora instance and a kafka broker.
