TransactionalWrite

trait TransactionalWrite extends DeltaLogging

Adds the ability to write files out as part of a transaction. Checks are performed to ensure that the data being written matches either the current metadata or the new metadata being set by this transaction.

    Normalize the schema of the query, and return the QueryExecution to execute.

    Normalize the schema of the query, and return the QueryExecution to execute. The output attributes of the QueryExecution may not match the attributes we return as the output schema. This is because streaming queries create IncrementalExecution, which cannot be further modified. We can however have the Parquet writer use the physical plan from IncrementalExecution and the output schema provided through the attributes.
