Incremental Data

Incremental Data

You can configure a mass ingestion specification to ingest incremental data, which is data that has been modified in between runs of the specification.
To ingest incremental data, enable incremental load in the specification and configure the following incremental load options:
  • Incremental key. The key that the Spark engine uses to fetch incremental data.
  • Incremental mode. The mode that the Spark engine uses to ingest incremental data.
If you ingest data to a Hive target, you can also propagate schema changes to accommodate for schema drift in the relational database.
If you do not enable incremental load, you can use only full loads to ingest the data. A full load ingests all of the data to the target each time that the specification runs.
