AWS Lambda Python: Can I load a file from local PC when calling my lambda?

Question

Situation: My AWS Lambda analyze a given file and return cleaned data.

Input: path of the file given by the user

Ouptut: data dictionnary

Actually in my lambda I:

save the file from local PC to an s3
load it from the s3 to my lambda
analyze the file
delete it from the s3.

Can I simplify the process by loading in the lambda "cash memory" ?

load it from local PC to my lambda
analyze the file

I mean: lambda "RAM" ----- lambda temporary variable storage ----- variables that will disappear at the end of the lambda. — Utopion

No we can not directly load the file from local to Lambda or its tmp memory.

But if you want you can use a Storage gateway which automatically sink any file from a physical drive( your local pc ) into S3. This would help you to eliminate your step 1 ( save the file from local PC to an s3 ).

First of all, you might use the wrong pattern. Just upload file to S3 using AWS SDK and handle lambda with S3:CreateObject event.

If you do that, where's the output from Lambda going to go?
