Currently BatchOperationExecutionScheduler (and BatchOperationInitializer) are doing too much. BatchOperationExecutionScheduler handles scheduling, retry logic, state management, and validation. BatchOperationInitializer handles pagination, chunking, command creation, and error handling.

Also:

• The mutable InitLoopState class and AtomicReference<ExecutionLoopState> make the code hard to follow and reason about.
• Methods like executeRetrying() and initializeBatchOperation() are doing multiple things and have complex control flow.
