Method Detail

splitOffsets

default java.util.List<java.lang.Long> splitOffsets()

Description copied from interface: ContentFile

Returns list of recommended split locations, if applicable, null otherwise.

When available, this information is used for planning scan tasks whose boundaries are determined by these offsets. The returned list must be sorted in ascending order.

Specified by:

splitOffsets in interface ContentFile<DeleteFile>

Returns:

List of recommended split locations, if applicable, null otherwise. When available, this information is used for planning scan tasks whose boundaries are determined by these offsets. The returned list must be sorted in ascending order.

referencedDataFile

default java.lang.String referencedDataFile()

Returns the location of a data file that all deletes reference.

The referenced data file is required for deletion vectors and may be optionally captured for position delete files that apply to only one data file. This method always returns null for equality delete files.

contentOffset

default java.lang.Long contentOffset()

Returns the offset in the file where the content starts.

The content offset is required for deletion vectors and points to the start of the deletion vector blob in the Puffin file, enabling direct access. This method always returns null for equality and position delete files.

contentSizeInBytes

default java.lang.Long contentSizeInBytes()

Returns the length of referenced content stored in the file.

The content size is required for deletion vectors and indicates the size of the deletion vector blob in the Puffin file, enabling direct access. This method always returns null for equality and position delete files.
