Spring batch Performance Issue - StaxEventItemReader and JAXB
Hello anyone who can help me,
I am using StaxEventItemReader and JAXB for marshalling and unmarshalling.
but I observed that the performance of treating an XML file is not good enough and I get out of memory exception.
I am trying to use another unmarshaller - xstreammarshaller , JIXB, xmlbeans, castor
Has anyone faced this kind of issues using spring batch?
Could anyone inform me which is the best performing marshaller please?
