Does AWS guarantee my lambda function will be triggered 100%?


Does AWS guarantee my lambda function will be triggered 100%?

it fixes the issue You don't mention how long the Lambdas take to execute. The default limit of concurrent executions is 1000. If you are uploading files faster than they can be processed with 1000 Lambdas then you'll want to reach out to AWS support and get your limit increased.
Also from the docs:

Can I retrieve the name of the AWS IoT Thing that triggered my Lambda function?

Can I retrieve the name of the AWS IoT Thing that triggered my Lambda function?

Hope this helps AWS IoT allow to associate multiple certificates to the same Thing and multiple Things to the same certificate. That makes detecting Things name quite challenging unless you adopted approach one certificate per Thing.
IoT clients do not invoke Lambda functions directly. Rather it is in effect a Rule that invokes a function. A Rule takes a JSON formatted message from the topic it is listening to, possibly modifying the data available to the Rule using SQL syntax and passes the result to the Lambda function as event parameter of your handler. By default Rule passes message to the Lambda exactly as it was published by the client without adding or removing any data, hence if the message has no data about "name" this data won't be available by Lambda function as well.
code :
SELECT *, topic(3) as thingName FROM '$aws/things/+/shadow/update/accepted'

hope this fix your issue API changes made in the API Gateway console typically don't take effect immediately. This is admittedly not always intuitive, but you need to "deploy" the API to a stage in order to push your changes live. Think of a "stage" as a pointer to a snapshot of configured behavior as it existed when the API rules were last deployed.
