  5. def addDefaultExprsOrReturnConstraints(deltaLog: DeltaLog, queryExecution: QueryExecution, schema: StructType, data: DataFrame): (DataFrame, Seq[Constraint], Set[String])

    If there are columns with default expressions in schema, add a new project to generate those columns missing in the schema, and return constraints for generated columns existing in the schema.

    If there are columns with default expressions in schema, add a new project to generate those columns missing in the schema, and return constraints for generated columns existing in the schema.

    deltaLog

    The table's DeltaLog used for logging.

    queryExecution

    Used to check whether the original query is a streaming query or not.

    schema

    Table schema.

    data

    The data to be written into the table.

    returns

    The data with potentially additional default expressions projected and constraints from generated columns if any.
