Allowing users to specify a default value for headers.

[landbaychrisburrell]

Hi

Are you open to allow users to customize at start-up (or some other means) the default value for the 'headers'. In our environment, we use a JSON-based header structure, some fields of which are mandatory one of which is the idempotency key and dynamic. It's reasonably time consuming to always have to refer back to the normal structure/copy&paste/change, etc.

Our default headers look something like like this

{
   "routingInfo" : "",
   "idempotencyKey": "unique-value",
   ...

}

Instead of typing this every time, it would be helpful to have it pre-populated. It would also be useful to have Kafbat refresh the headers each time replacing the unique value -

So i would suggest

• Sourcing a 'template' from the environment/configuration set-up
• Allowing a parameter (or others) such as 'UUID' that would get replaced on the way in to displaying the headers.
