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.

Bad idea. First, file is read sequentially, and you can't parallelize this. Second, grep is a bad solution for structured files. Better use jq or something similar.

First time hearing about it, but JSONL is like CSV with json per line. So not really structured.

I don’t see why you couldn’t just use grep on it.
