SupportsDynamicOverwrite

trait SupportsDynamicOverwrite extends WriteBuilder

Write builder trait for tables that support dynamic partition overwrite.

A write that dynamically overwrites partitions removes all existing data in each logical partition for which the write will commit new data. Any existing logical partition for which the write does not contain data will remain unchanged.

This is provided to implement SQL compatible with Hive table operations but is not recommended. Instead, use the overwrite by filter API to explicitly replace data.

  5. def buildForBatch(): BatchWrite

    Returns a BatchWrite to write data to batch source.

    Returns a BatchWrite to write data to batch source. By default this method throws exception, data sources must overwrite this method to provide an implementation, if the Table that creates this write returns TableCapability#BATCH_WRITE support in its Table#capabilities().

    Returns a StreamingWrite to write data to streaming source. By default this method throws exception, data sources must overwrite this method to provide an implementation, if the Table that creates this write returns TableCapability#STREAMING_WRITE support in its Table#capabilities().
