Vercel's post explains that the real problem with serverless compute and database connections is not the number of connections during normal operation, but connection leaks caused when functions are suspended. It describes how Vercel Fluid Compute's waitUntil feature can close idle connections before suspension, and provides a one-line code example using attachDatabasePool from @vercel/functions.

## Evidence

Verbatim from https://vercel.com/blog/the-real-serverless-compute-to-database-connection-problem-solved:

> In modern serverless platforms like Vercel Fluid Compute , the issue of the leaked connections can be solved. Fluid supports a feature called waitUntil , which allows a function to remain alive just long enough to complete work after the main request finishes.
