Performance issue with MultiResourcePartitioner in Spring Batch

问题

I have a spring batch project that reads a huge zip file containing more than 100.000 xml files.

I am using MultiResourcePartitioner, and I have a Memory issue and my batch fails with

java.lang.OutOfMemoryError: GC overhead limit exceeded.

It seems like if all the xml files are loaded in memory and not garbaged after processing.

Is there a performant way to do this ?

Thanks.
