Is it normal if 1 million IDs from a table are read using JdbcCursorItemReader

  • 0

Is it normal if 1 million IDs from a table are read using JdbcCursorItemReader and written to a file using FlatFileItemWriter and the process takes 5 hours?

Spring suggests using JdbcCursorItemReader for improving performance and I have already used that. What else can be done?

Can I skip the row mapper altogether as I am converting ID fetched to a Map entry (Map) in the mapper and fetching the ID from the Map while writing which seems useless.

Is Spring batch the ideal approach for such scenarios?

Thanks in Advance
