How to describe Lambda cold start problem?

It happens when Lambda reuses existing container and wait till the previous execution is completed

It happens when you execute an inactive function

This is the overhead in starting a Lambda invocation

It happens when Lambda code is downloaded from S3 bucket in different region than the execution

When cold start problem is usually visible?

After a fresh deployment

When there are no request to a given Lambda for some time

When data in the Lambda request has changed

All of the above

What has an impact on Lambda execution time?

Programming language

Memory allocation

Package/code size

All of the above

What lifecycle phases contribute to the cold start problem?

Starting your code

Starting new container

Bootstraping the runtime

Downloading your code

How to prove that the Lambda reuses existing container?

There are Lambda metrics that show how many times new container was created vs. Existing container was reused

Create a static variable, increment and log it in the handler method

Lambda logs contain execution parameters, including information if container was reused or not

Save some file in /tmp directory if it doesn't exist or log the file content otherwise
