public interface DeltaWrite
extends org.apache.spark.sql.connector.write.Write
A logical representation of a data source write that handles a delta of rows. A delta of rows is
a set of instructions that indicate which records need to be deleted, updated, or inserted. Data
sources that support deltas allow Spark to discard unchanged rows and pass only the information
about what rows have changed during a row-level operation.
