Does Realm functions have cold start like AWS lambda?

MongoDB Atlas App Services & Realm Atlas Triggers & Functions
1

Hi Team,

I want to know if Realm functions behave like AWS Lambda or not. AWS lambda starts like this

  1. Lambda container launches
  2. Loads my code
  3. Run code

and how how long does Realm function take until it starts to run my code ?

Similar question please…

Under the hood, are realm functions using aws Lambda? I’m asking for capacity planning and to understand if these will be as reliable and predictable as lambdas under heavy load?

Still no reply? @mongodb_mongodb

FaunaDB claims that MongoDB has cold starts. Do you have official answer from the MongoDB team about functions?

Atlas Functions do not suffer from cold starts in the way that lambda functions do.

The engine behind App Services transpiles all functions into golang and runs them natively which means that they run immediately without any type of provisioning.
