Ansible: How to execute ALTER statements on database with delay? - ansible

Question

I have generated a file with bunch of alter statements based on certain condition on cluster using Ansible task.
Here's the sample file content
alter table test1 with throttling = 0.0;
alter table test2 with throttling = 0.0;
alter table test3 with throttling = 0.0;
I want to login and execute these ALTER statements with a delay of 2 mins. I was able to achieve this with a shell script using sleep command by copying the shell script from Control Node and execute on Remote Node.
But the problem we noticed was we were unable to check if script executed properly or failed (like authentication failed to DB, etc.)
Can we perform the same task using Ansible module and execute them one by one with some delay?

the short answer, yes, of course.
A slightly longer minimal example
- name: Run queries against db test_db with pause
community.mysql.mysql_query:
login_db: test_db
query: "ALTER TABLE test{{ item }} WITH throttling = 0.0;"
loop: [1, 2, 3]
loop_control:
pause: 120 # seconds
