1. How do you get around performance issues? If I have a difficult join and you have a slow database, or you have a flaky connection, how can I debug the problem on my end?

2. What stops me (or any attacker) from exploiting your lack of security? Are you 100% sure you are secure?

3. You mention collaboration - How does this work at a company level if we have many users and need to control access - the company is the entity with rights to the data in this case.
