It happens when the AWS Lambda function timedout already when sst start sent the response back

09/08/2021, 8:11 PMhuh.. so. ah! ok, I know why
Sam Hulick
09/08/2021, 8:11 PMthe Aurora Serverless DB wasn’t spun up. so Lambdas will always time out
Sam Hulick
09/08/2021, 8:13 PMthanks for the help 🙂

hmm sst start sets a timer on each request with a timeout same as thr Lambda functions's timeout. And ur local function should gets killed when the timeout is reached.

You shouldve seen a timeout error locally as well... 🤔

Sam Hulick
09/08/2021, 8:15 PMyeah, no timeout error. just the one I pasted

Hmm what was the lamda's timeout set to?
s
Sam Hulick
09/08/2021, 8:16 PM10 seconds I think
Sam Hulick
09/08/2021, 8:17 PMI leave it at default, unless it’s doing media processing or any kind of long-running process. then I go for 5-10 minutes

Frank
09/08/2021, 8:17 PM
i see. and how long did the function run for locally before you got the 201 response?
Frank
09/08/2021, 8:17 PM
roughly 10s maybe?
s
Sam Hulick
09/08/2021, 8:17 PMnot sure, this came from my dev
Sam Hulick
09/08/2021, 8:18 PMI’ll keep an eye out for it next time

09/08/2021, 8:30 PMWe've found Aurora startup times to be really long, often over a minute. v2 is supposed to be much faster but it's been in preview for 46 years.
Consequently we've decided to migrate everything to DDB (also should save us money with associated VPC, NAT GW and the cost of Aurora)
s
Sam Hulick
09/08/2021, 8:31 PMI would’ve used DDB but it just wasn’t a good fit. we need to be able to arbitrarily sort on any column, ascending & descending. our data is very tabular

Ross Coundon
09/08/2021, 8:35 PMyeah, certainly doesn't fit everywhere. I think if we were doing it again we'd look outside of AWS for a SQL based option

09/09/2021, 2:44 AMAurora v1 serverless IMO is not viable, I think it's better to just pay for a 24/7 normal cluster
thdxr
09/09/2021, 2:45 AMHighly recommend planetscale if you need serverless sql
s
Sam Hulick
09/09/2021, 2:46 AMAurora Serverless is ok, you just can't use the auto pause feature in production. I'm using it in dev only to save $

09/09/2021, 2:46 AMyeah makes sense in dev

09/09/2021, 6:22 AMBecause of our usage patterns we could make it work but needed to build in a wake-up lambda running on a cron
