I'm using a Jupyter Notebook on a Spark EMR cluster, want to learn more about a certain command but I don't know what the right technology stack is to search. Is that Spark? Python? Jupyter special syntax? Pyspark?
When I try to google it, I get only a couple results and none of them actually include the content I quoted. It's like it ignores the %%.
What does "%%spark_sql" do, what does it originate from, and what are arguments you can pass to it like -s and -n?
An example might look like
%%spark_sql -s true
select
*
from df
