      key - The key of the entry to filter
      value - The value of the entry to filter and then convert
      metadata - The metadata attached to the entry
      Returns:

    • format

      The desired data format to be used in the KeyValueFilter.accept(Object, Object, Metadata) operation. If null, the filter will receive data as it's stored.
