We are using Spring Batch to do some processing, reading some ids via Reader and we want to process them as 'chunks' via a processor then write to multiple files. But the processor interface allows only one item to processed at a time, we need to do bulk processing because the processor depends on a third party and calling the service for each item is not an option.
I saw that we can create Wrappers for all Reader-Processor-Writers involved in the 'chunk' to handle List<> and delegate to some concrete reader/processor/writer. but that doesn't seem all nice to me. Like this:
<batch:chunk reader="wrappedReader" processor="wrappedProcessor" writer="wrappedWriter"
commit-interval="2"/>
Is there a 'chunking' option that lets chunking before the processor? rather than before Writer.
Cheers,
I'd recommend reconfiguring your ItemReader to return the "chunk" that needs to be processed since that's really the "item" you're processing is.
