Is boto3 clients and resources support LambdaSnapstart ?

[maxcharlier]

Hello,

I would like to know if boto3 already implement

@register_after_restore
def after_restore():

at the Python __init__ class level or do we have to check network connection our self when using Snapstart ?

I mean if I have boto3.client('dynamo-db") in my cold start to we have to implement a logic to check if the connection is still live or not after the restart ?

Best regards

If you look at the AWS Lambda documentation, this is already outlined.

Always re-establish your network connections when your function resumes from a snapshot. We recommend that you re-establish network connections in the function handler.

Further flexibility can be utilized with runtime hooks.
