Hi,
Based on what you have described, it seems you are looking for some admin / reporting tools. As far Cloud SQL is concerned, I was able to find a third party application called MySQL Workbench. You may find the official guide for using this tool with Cloud SQL
here. I am not sure if the MySQL workbench is open sourced. However, it is one of the tools listed on our documentation for administration operations. You may feel free to explore the possibility of embedding this application into your code.
In regards to your concerns with HIPAA, there is a Enterprise Edition of the workbench called:
MySQL Enterprise Edition. My research into the MySQL documentation indicates that this edition has a
Enterprise Audit feature. You may find further information about this third party product
here.
Lastly, it would be a good idea to check our documentation for best practices regarding securing cloud databases
here. Also, there is some
HIPAA compliance documentation provided to our customers that could be of some use to you.
I hope this helps!
