I have a simple problem: I load A 3 GB dump of a DB that I read in lazily using 'csv-read' from a local file. I try to group by doing: (Group-by first lazy-csv) The problem is I run out of memory even when I bump the VM's max memory to 10GB

What's going on?

I should have enough resources to perform this operation.

I don't want to go back to Python or spark to do a simple thing

Is the persistent data structures getting in the way?
