Spring-Batch-multi-threaded-step
================================

This project features:
  - a simple test case to see how a multi-threaded step executes in Spring Batch (MultiThreadedStepTest)
  - a typical real-world sample that leverages Spring Batch's multi-thread step execution (BusinessJobMultiThreadedStepTest)

The approach in the real-world example would be suitable for jobs where reading is cheaper and faster 
than processing and/or writing. Jobs with CPU-intensive tasks in processing and/or writing on multi-core systems would
also benefit from this approach. Same thing for I/O-intensive or high-latency jobs (web service call, etc).
The processing/writing source would typically be the bottleneck, so contention should as small as possible.
Restartability is enabled thanks to a dedicated flag (reader selects unprocessed items, writer marks the item
as processed just after the business processing).
