The OP said he was successful in splitting his huge file and putting each chunk into a thread for processing, but was unsure on how to collect the output generated by each thread. He said a database write was unacceptable to his boss.

The concept of each thread writing to it's own output file and merging them after script completion didn't appear a good solution to him, or else he wouldn't have brought the issue up.

Consider a situation where the threads process millions of records, but only need to report back a few matches. This method will allow the main thread to collect those matches, and operate on them in realtime. Otherwise the main thread would have to tail the thread's output files.

I'm not really a human, but I play one on earth.
