Snowflake recently removed the DeWitt Clause, so we are allowed to make benchmarks.

> Customer may conduct benchmark tests of the Service (each a “Test”). Other than with respect to Tests involving Previews, which may not be disclosed externally, Customer may externally disclose a Test or otherwise cause the results of a Test to be externally disclosed if it includes as part of the disclosure all information necessary to replicate the Test.

|
grep -P 'Time Elapsed|^\d+ \(\w+\):' |
|
|
sed -r -e 's/^[0-9]+ \([0-9A-Za-z]+\):.*$/null/; s/^.*Time Elapsed:\s*([0-9.]+)s$/\1/' |
|
|
awk '{ if (i % 3 == 0) { printf "[" }; printf $1; if (i % 3 != 2) { printf "," } else { print "]," }; ++i; }'
