Nice work, this was on the backlog for a long time :-) We need to adapt the instructions https://catalog.us-east-1.prod.workshops.aws/workshops/f2c0706c-7192-495f-853c-fd3341db265a/en-US/microservices and can merge it afterwards. |

Can I suggest we add the tiered compilation stop at level 1 config as well. |
|
The workshop uses manual creation of a Lambda function via AWS Console. Most likely this has to be a step in the workshop guide. |

Tested adding tiered compilation stop at level 1 config. Init duration (cold start) reduced from 1769ms to 1560ms @msailes |
