Event Schema - How to get schema along with the data

[sunny1978]

After subscribing, I am getting the event data like
{"event":{"createdDate":"2018-11-20T18:20:23.383Z","replayId":2,"type":"updated"},"sobject":{"Email":"test@email.abc","Id":"someid","Name":"Test 2"}}
I would like to receive schema too. I cannot just post this data to down stream apps. I need associated schema with it. This helps downstream apps to adopt to changes like adding new fields, deleting etc.

Forget the adhoc changes, I still want to receive schema along with data even with fixed schema.

Kindly help us.
