Challenge of Serverless: Database Connections

  A module for managing MySQL connections at SERVERLESS scale

This problem is not specific to Redis, it applies to all databases which rely on TCP connections (Mysql, Postgre, MongoDB etc). You can see the serverless community is creating solutions like serverless-mysql. These are client-side solutions. As Upstash, we have the advantage of implementing and maintaining the server-side. So we decided to mitigate the problem by monitoring the connections and evicting the idle ones. So here the algorithm: As max-concurrent-connection, we have two limits for a database, soft-limit and hard-limit. When a database reaches the soft-limit we start to terminate the idle connections. We continue to accept new connection requests until the hard-limit is reached. If the database reaches the hard limit then we start rejecting new connections.
