XML parsing from entity bytestring

Hello,

While using akka-stream-alpakka-xml with akka http requests, I noticed interesting behavior when parsing large xml files.

Detailed scenario is as follows:

• user posts xml file using akka http endpoint
• xml is then taken from request entity as bytestring source and parsed by XmlParsing.parser

XmlParsing logic works with the same xml without akka http, or when I first materialize it by Unmarshal(httpRequest.entity).to[String] and pass it as Source.single(Bytestring) to XmlParsing.parser.

When I run source.via(XmlParsing.parser), where source is from akka http request (request.entity.dataBytes), I almost always see that some keys from xml are splitted:

testuser/one/two/three/four/five/six/seven/eight/nine/ten/eleven/twelve/sub736/KM8DaDXEVNP4MByygsM8d5vK96NStFJC=87i and
zFQw0lL90.txt

I susspect that this is related to fact that parsing is faster then source?

What do you think?
