Data Format

  • Binary: Data is transferred directly. It is not converted to another format. This setting is suitable for file migration.
  • CSV: Source data will be migrated after being converted in CSV format.
  • JSON: Source data will be migrated after being converted in JSON format.
  • CDC (DRS): Source data will be migrated after being converted in DRS format.
  • CDC (JSON): Source data will be migrated after being converted in JSON format.
  • CDC (DRS_AVRO): Source data will be migrated after being converted in DRS_AVRO format.
  • CDC (DRS_JSON): Source data will be migrated after being converted in DRS_JSON format.

Binary

Offset

Initial offset parameter

  • Latest: Maximum offset, indicating that the latest data will be extracted.
  • Earliest: Minimum offset, indicating that the earliest data will be extracted.
  • Submitted: data that has been submitted
  • Time Range: data within a specified time range

Latest

Data Extraction Timeout Duration

Maximum duration (minutes) of data extraction. For example, a job scheduled daily needs a sufficient duration to extract the data generated by the topic every day.

Suspension Period

If the value is set to 60 and no data is returned within 60s after the consumer requests data extraction from Kafka (generally because all the data in the topic has been read or the network or Kafka cluster is unavailable), the task will stop immediately. Otherwise, the system will retry reading data.
