Spring Batch ItemReader control

[Krishna Das]

Hi,
We have a simple scenario where we have to control the execution/ termination of the "ItemWriter" based on the file size of the file used by "FlatFileReader".

We are using the "FlatFileReader" to read from a csv file and "JdbcBatchItemWriter" to write into the oracle database.

Since the writing into the DB is always comparatively expensive, I thought of mitigating the cost of executing the ItemWriter if the file is 0kb.

Please let me know, if spring batch has a solution for this scenario and if it does, please let me know how to configure/ write code to get this done.


Thanks

Hi,
I suppose FlatFileReader don't read anything and don't kick Writer if file ist 0kb (emphy). If not so, just extend the FlatFileReader to ignore 0Kb file

What does the reader read, an empty String ?
What does the writer write in your usecase ?
