Our pup Freyja isn’t very interested in playing fetch– if I throw a ball, she usually ignores it.

Occasionally, though, she compiles and caches the right execution plan, and we get a game in for a while:

Should you read execution plans from right to left (like the data flows), or from left to right (order of execution/callers)?

I like​ Hugo Kornelis’ answer​, which is, “whatever helps me understand the logic of this execution plan.”
