-- | Describes updates or additions to a dataset. A Single update or addition
-- is an entry (JSON Line) that provides information about a single image.
-- To update an existing entry, you match the @source-ref@ field of the
-- update entry with the @source-ref@ filed of the entry that you want to
-- update. If the @source-ref@ field doesn\'t match an existing entry, the
-- entry is added to dataset as a new entry.
--
-- /See:/ 'newDatasetChanges' smart constructor.
data DatasetChanges = DatasetChanges'
  { -- | A Base64-encoded binary data object containing one or JSON lines that
    -- either update the dataset or are additions to the dataset. You change a
    -- dataset by calling UpdateDatasetEntries. If you are using an AWS SDK to
    -- call @UpdateDatasetEntries@, you don\'t need to encode @Changes@ as the
    -- SDK encodes the data for you.
