- def copyInto(tableName: String, targetColumnNames: Seq[String], transformations: Seq[Column], options: Map[String, Any]): TypedAsyncJob[Unit]
Executes
CopyableDataFrame.copyIntoasynchronously.Executes
CopyableDataFrame.copyIntoasynchronously.- tableName
Name of the table where the data should be saved.
- targetColumnNames
Name of the columns in the table where the data should be saved.
- transformations
Seq of Column expressions that specify the transformations to apply (similar to transformation parameters).
- options
Map of the names of options (e.g.
compression,skip_header, etc.) and their corresponding values.NOTE: By default, theCopyableDataFrameobject uses the options set in the DataFrameReader used to create that object. You can use thisoptionsparameter to override the default options or set additional options.- returns
