Pass the StepExecution to the Partitioner API

[djechelon]

In order to take an if-else decision based on job arguments (specifically, my job can be executed against a "reference date" so I can pass it from command like), I would like to use that information in the Partitioner to select files/item/rows according to that information.

Currently, only information available is the grid size. According to SimpleStepExecutionSplitter, the StepExecution is available before calling the Partitioner.

I would kindly ask if it is possible, for the next version, to add the parameter to the Partitioner interface

Thanks for your attention

Thank you for opening this feature request. We need a concrete example that shows the limitation of the current API to introduce such a big change. Can you please provide a code example for your use case?

From what I understand, the implementation of your partitioner depends on a job parameter. In this case, you can declare your partitioner as a step-scoped bean and use late binding to inject job parameters. If you elaborate with more details, I can try to give an example.
