If I understand spring correctly, then the reader reading mechanism does not provide a multithreading mechanism at the reading stage. I play with some ideas around using modular arithmetic in the primary key of a database as a mechanism for partitioning query multithreading. My questions are doubled:
(1) Did I miss something about the ability to run multiple threads during the reading phase, especially regarding the creation of database queries?
(2) If I come up with a good solution, would it be useful to open Jira for this and send it back to spring -batch codebase? Obviously, https://github.com/spring-projects/spring-batch/blob/master/CONTRIBUTING.md will be the starting one, but the Spring guys don't seem to have a visible mailing list for communication. So I decided that I was asking a question before opening a ticket.
