Defined in:
lib/bulk_csv_parser/import_job.rb

Overview

Runs BulkCsvParser::Processor in the background via ActiveJob, so large CSV uploads don't block a web request. Enqueue it via BulkCsvParser.enqueue rather than calling perform_later directly -- that helper is what puts the file somewhere the worker (often a different machine than the one that received the upload) can actually read it back from.
