How to tell if blaze has kicked in?

[mattwparas]

I'd assume that if I were to check the query plan I'd see things related to "native" stages - is that true? Is it guaranteed that something like parquet scan will translate to a native plan?

More or less - I'm not sure if my setup is incorrect or if I'm looking in the right place to check things

Checking the query plan is indeed an effective way to determine if Blaze has intervened.

I think if the "native" phase appears in the query plan and you have enabled Blaze as described above, then Blaze can be considered effective.
