and see this in input:

The chunk size has been set to 2
Reader
Reader
Writer
[reeeeader, reeeeader]

The chunk size has been set to 2
Reader
Reader
Writer
[reeeeader, reeeeader]

The chunk size has been set to 2
Reader
Reader
Writer
[reeeeader, reeeeader]

..and so on. Need advice.

Answer 1

A step will only stop when it reads null values in its ItemReader implementation.You need to make sure that the reader implementation reads and returns null at some point of time. Then the step will stop on its own.
