Description

Stéphane Nicoll opened BATCH-1613 and commented

The attached classes implement a scenario where a singe file is read by a partition. It's limited to one item = one line (only the method that does count the number of items in the input file though).

Attached also is a sample Job configuration file demoing the functionality (not runnable as is though)


Affects: 2.1.0

Research direction

Start by reviewing the attached sb-multi-threads-reader.zip classes and the sample Job configuration, then read the referenced pull request #147 and the linked BATCH-1613 discussion. Determine the complete scope beyond counting one-item-per-line input, and confirm what single-file partition reading should support before considering the work done.
