I was wondering if anyone knows the proper way to write a benchmarking test for the @>> operator. I used the below script in my previous attempt https://gist.github.com/markrofail/174ed370a2f2ac24800fde2fc27e2d38
The script does the following steps:

1. Generate Table A with 5 rows
2. Generate Table B with n rows such as:
every row of Table B is an array of IDs referencing rows in Table A.

The tests we ran previously had Table B up to 1 million rows and the results can be seen here :

How would we change this so it would be more exhaustive and accurate?

Mark Rofail
