A Document object can take approximately 10 times as much memory as the size of the XML. For example, a 1 MB XML document may use 10 MB of memory. If many splits are generated due to the size of the XML, a two-phase approach may be necessary to avoid excessive use of memory.") public class SplitXml extends org.apache.nifi.processor.AbstractProcessor
