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.
