Aggregating & transforming large data into file.

Hi , 

I have a requirement that , every day I need to query the database for
updated profile records and then out of those records get the BLOB object
which is in the form of xml. 

I need to tranform this (BLOB object ) xml into another xml.

And then create a single large xml file out of all these transformed xmls. 


I have two thoughts as of now 

1) For every source xml create a JAXB object by marshalling /unmarshalling
convert it into another object and 
then apply aggregation on transformed xml Object.

2) Aggregate all the xmls and then apply transformation (xslt) and generate
one file xml.

Since the file data is very large I am little worried about performance.

Please suggest if there are any alternative ways or which way it better in
the above case.


Versions: Java 1.7
Camel : 2.11.0


Thanks 
Sri
