public interface V1WriteBuilder
A trait that should be implemented by V1 DataSources that would like to leverage the DataSource
V2 write code paths. The InsertableRelation will be used only to Append data. Other
instances of the [[WriteBuilder]] interface such as [[SupportsOverwrite]], [[SupportsTruncate]]
should be extended as well to support additional operations other than data appends.
This interface is designed to provide Spark DataSources time to migrate to DataSource V2 and
will be removed in a future Spark release.
Creates an InsertableRelation that allows appending a DataFrame to a
a destination (using data source-specific parameters). The insert method will only be
called with `overwrite=false`. The DataSource should implement the overwrite behavior as
part of the [[SupportsOverwrite]], and [[SupportsTruncate]] interfaces.
