Description

Headers should be specific to plantform-shared-lib, and not have the underlying node-rdkafka lib header exposed directly to the client of this lib.

Ref:

• platform-shared-lib/modules/nodejs-kafka-client-lib/src/rdkafka_producer.ts

  Line 37 in b870ec3

  import { MessageHeader, NumberNullUndefined } from "node-rdkafka/index";

• platform-shared-lib/modules/nodejs-kafka-client-lib/src/rdkafka_producer.ts

  Line 170 in b870ec3

  const headers: MessageHeader[] = [];

Proposal:

Create own type for headers as follows:

{
  header1: val1,
  header2: val2
}

The reason for this proposal are:

1. We should NOT be exposing the underlying types to the DM clients
2. The above proposal is more widely used within the NodeJS community (i.e. express, etc), and will allow for smoother easier interoperability (with the underlying lib implementation handling the transformation to the underlying client lib format for headers).
