Creates a default batch fraction.
<p>
Uses an {@code in-memory} job repository with the {@linkplain #DEFAULT_JOB_REPOSITORY_NAME default name}.
</p>

<p>
Uses a default thread-pool with a calculated maximum number of threads based on the available number of processors. A
keep alive time of 30 seconds is used for the thread-pool.
</p>

@return a new default batch fraction
