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

Answer 1

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

Answer 2

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 ).
