I asked ChatGPT the same question again and then followed up with:

“Is there a more efficient way to connect to the database”

It then went off the rails. It gave me generic answers about using connection pooling that your language framework provides.

Of course that doesn’t help with each Lambda being invoked separately.

I then asked “But each Lambda runs based on its own vm”

It then correctly said that while each Lambda invocation would have its own pool and couldn’t be shared, it could be shared with multiple connections during one invocation.

Which is technically correct. But not the answer I was looking for.

In all fairness, it’s the same type of answers I would expect from a junior to mid developer with limited experience with AWS. I would hire a person who could answer that well.
