Python script to warm AWS lambda for cold start problem












1















I followed the lambda-warmer https://github.com/jeremydaly/lambda-warmer for NodeJS to create a similar script for python:




  • Warm the lambda function every a few minutes

  • Warm more than one lambda functions if I set up the concurrency parameters


Here is my python code:
https://github.com/pafun/lambda-warmer-python/blob/master/lambda-warmer-python.py



Here is a typical input:



{
"flag": "warmer",
"concurrency": 10,
"test": false,
"delay": 300
}


Usually, the script won't warm up the exact number of instances for me unless I increase the delay time. Like the above example input, I usually get 6-8 Concurrent Executions as I observed in lambda AWS monitor.



How can I make sure the exact number of lambda instances will be warmed?
