Key Value Dataset Sink (Deprecated)
- Robin Rielley
Note: Datasets and the Key Value Dataset Sink are deprecated and will be removed in CDAP 7.0.0.
Writes records to a KeyValueTable, using configurable fields from input records as the key and value.
The source is used whenever you need to write to a KeyValueTable in batch. For example, you may want to periodically copy portions of a Table into a KeyValueTable.

It takes records with the following schema as input:
