How to do this.

Any other method of doing this ?

1. i have a reader , which read data-base, gets data,
2. now for each record, i need to query the different database to get a lot of data and write to DB.

i can use the Item processor, but the data is huge, i cannot hold the data in memory and pass it to writer.

How do i process this ?

any better alternate approach ?

Maybe you can turn your reader into a Partitioner, and split the work across multiple step executions?

Thanks Dave,

Yes, Your suggestion from other posts helped to choose that route.
