Invoke specified CloudWatch Rule on MediaConvert Event

Question

I use _AWS Lambda_ that executes _MediaConvert_ for video transcoding and _AWS CloudWatch Events Rule_ for executing another one _AWS Lambda_ when _MediaConvert_ job status was changed  and log changed status in db(e.g. DynamoDb).   
  
We have the following data flow:    
**Lambda** -> **MediaConvert** -> **CloudWatch Event Rule** -> **Lambda for processing job status** -> **DynamoDb**  
So it works fine if I have 1 environment, but when we have 2 or more environments this flow doesn't work.  
  
It seems MediaConvert can execute only 1 **CloudWatch Rule Event** for 1 Event.   
By this reason there is can be a case when you send job to transcoding from the 1st environment, but **Lambda for processing job status** was executed from the 2nd environment (because  **CloudWatch Event Rule** from the 2nd environment pull MediaConvert Event )  
  
Is there is a way how I can achieve to execute **Lambda for processing job status**   
 and **CloudWatch Event Rule** exactly from the 1st environment

Answer

Hi there,  
  
You can also key off userMetadata from the job payload.   
  
The example below would trigger a cloudwatch event based on the following conditions:  
  
Service source is mediaconvert  
Job status is COMPLETE  
And userMedadata in the job json has  key pair of env  and Prod.

```
{
  "source": [
    "aws.mediaconvert"
  ],
  "detail": {
    "status": [
      "COMPLETE"
    ],
    "userMetadata": {
      "env": [
        "Prod"
      ]
    }
  }
}
```
