I have a pretty constant-use case in mind for collecting client metrics with different loads and spikes throughout the day and am mostly interested in paying a little extra to not have to manage the RDS/Aurora server instances. I basically just need a k/v store but need to do report queries/scans so DynamoDB isn’t a good fit. (COUNT(*) FROM, SUM, etc..)
Looks like a minimum of 5 minutes of usage each time the database is activated and I’m pretty sure my load will never let the database shutdown so that might solve the cold-start issue.
