Change Data Capture in Trigger

I am sharing an example that how can use CDC in Apex Change Event Trigger to Predict Account Status

Because Apex change event triggers run asynchronously, they typically contain time-intensive processes that run after the database transaction is completed. This trigger example covers a more common real-world scenario than the trigger given in the quick start. It captures case changes and predicts the account trust status using an Apex class. The prediction is based on counting the account cases and checking case fields. In other scenarios, you might have complex prediction algorithms that are more resource-intensive.

The trigger calls a method in an Apex class to perform the trust prediction on the accounts related to all cases in this trigger. An account status of Red means that the account trust level is low because too many cases are associated with this account among other criteria. An account status of Green means that the trust level is good. The associated class is listed after this trigger. This example assumes that you have the following prerequisites.
A platform event named Red_Account__e with two fields: Account_Id__c of type Text and Rating__c of type Text
The SLAViolation__c custom field on the Case object of type Picklist with values Yes and No
