  jobOperator.restart(JobExecutionId)

starts a new job instance and don't resume job from the last chunk but just from last step. I need to resume the job from the last chunk written.

My reader is a custom RestReader that count first the total of items to process and then read this exact number from api. I'm using @StepScope annotation because I need custom variables in custom reader

Spring Batch restart functionality not working when using @StepScope.

Is it possible to resume the job from last chunk written or the problem is my custom reader?

Your RestReader must implement ItemStream. This is the contract that stateful item readers should implement. The ItemStream#update method will be called at chunk boundaries to save any contextual data required to restart from the last checkpoint in case of failure.
