amazon s3 - Downloading, updating & reloading file back to s3 using AWS Lambda function -


i have 3 simple individual python scripts using boto3 library downloading, updating & reloading file s3 bucket in aws, working fine.

however, wondering if same possible using aws lambda function? experience sharing appreciated.

your scripts should work fine aws lambda long fine following limitations:

  • need @ max 1536mb of memory
  • need @ max 512mb of temporary disk space
  • finish in less 5 minutes

for full list of limitations of aws lambda have @ http://docs.aws.amazon.com/lambda/latest/dg/limits.html

you react s3 events when using aws lambda, e.g. execute script anytime new object created in s3. check out documentation if you're interested in that: http://docs.aws.amazon.com/lambda/latest/dg/invoking-lambda-function.html#supported-event-source-s3
