How would you design parallel grep for huge JSONL files? (lemmy.world)

I need to scan very large JSONL files efficiently and am considering a parallel grep-style approach over line-delimited text.

Would love to hear how you would design it.

I think mmap is unlikely to be the best option seeing as you'd be doing large sequential reads.
