Interface V1WriteBuilder

All Superinterfaces:

WriteBuilder

@Unstable
public interface V1WriteBuilder
extends WriteBuilder

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.

Since:

3.0.0

Method Detail

buildForV1Write

InsertableRelation buildForV1Write()

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.
