I haven't seen it mentioned yet, but it reminds me of PQL (not PRQL): https://pql.dev

It's inspired by Kusto and available as an open-source CLI. I've made it compatible with SQLite in one of my tools, and it's refreshing to use.

An example:

  StormEvents
  | where State startswith "W"
  | summarize Count=count() by State
