Has anyone considered running PostgREST as an AWS Lambda ?

[fusionbeam]

AWS Aurora Serverless v2 begs the question: can PostgREST be run as an AWS Lambda? And would it be perform?

I am considering it for a very elastic pay-on-demand service in production that does not see schema changes too often.
AWS Lambda being a stateless service the question is how much state does Postgrest need?
If we were to serialise the cached schema to a file and bundle it in the lambda runtime would that suffice?

Thanks,

I have not, but I always wondered whether postgrest could also be used in a useful way as a library and not an executable. Just found this: https://theam.github.io/aws-lambda-haskell-runtime/. Maybe it's possible to use that to hook the postgrest core up to aws lambda.

Just a note though. I have no intention to even try myself.

Unfortunately I'm on the same boat for the meantime too. That being said I believe it would be useful to have library mode for postgrest.

That seems possible. It might even be few lines of code to read a JSON file with Aeson and our SchemaCache data type.
