Option for sequential/parallel read

[jayhohoho2019]

From v1.2.3 release notes: Added an option to revert to sequential read. There are some systems (primarily macos+exfat) where the parallel read features results in very long lookup times. This addition makes the parallel feature the default, but adds the ability to disable it and revert back to sequential reads.

Which option is this and how do we change it? Could we selectively do sequential read on certain plot_directories while parallel reads on all others, on the same harvester?

No, you cannot mix and match
