I found Clickhouse easier to handle than pure SQL for this - as an analytics database it has conveniences like parsing input files with regexp, user defined functions and array functions. It's often possible to treat it more like an array programming language. But I still sometimes couldn't avoid the tuple explosion problem.

I'd like to check what is the tuple explosion problem.
