      • getSourceKeyColumns

        @BetaApi
public abstract java.util.List<? extends ForeignKeyColumnDescriptor> getSourceKeyColumns()
        Get the source key declaration associated with this entity provider config. A source key is composed of one or more source key columns, each referring to one key column of the source vertex provider. Use getValidatedSourceKeyColumns() ()} instead of this function, as that function will also consider legacy configs.
        Returns:
        Source key columns declared in the config.
        Since:
        25.2.0

      • getValidatedSourceKeyColumns

        @BetaApi
public java.util.List<? extends ForeignKeyColumnDescriptor> getValidatedSourceKeyColumns()
        Validate and get the source key declaration associated with this provider configuration. This function will use the source key returned by either getSourceKeyColumns() or legacy function.
        Returns:
        A list of validated foreign key column descriptors.

        @BetaApi
public abstract java.util.List<? extends ForeignKeyColumnDescriptor> getDestinationKeyColumns()
        Get the destination key declaration associated with this entity provider config. A destination key is composed of one or more destination key columns, each referring to one key column of the destination vertex provider.
