I have a spring batch program with itemReader, itemProcessor and itemWriter.

Say I have 10,000 records to process. For each item I want to fetch data from several database table for deciding some conditions and adding some data.

I believe this will be done during processing.

Question: What is the best design to do this ? I am bit skeptic about running several Select queries for each item injecting SimpleJdbcTemplate in itemProcessor. Is there any other efficient way to do this ??

Thanks in advance!!
