=== Background
Data Products and Data Platform Engineering have arrived at an alternative to dynamically creating/destroying stream configs: We create a stream per Metrics Platform Base Schema and submit all Base-Schema-conforming events to those streams. Product Analysts will need to distinguish between events submitted by different instruments and so we will update the Base Schemas to include discriminating/filter fields (see T366802). We will also need to update the Metrics Platform Client Libraries so that they can accept values for those fields, i.e.
```typescript
type Event = Record<string, any>;
module mw {
interface eventLog {
submit( streamName: string, schemaID: string, event: EventRecord<string, any> ): void;
}
}
```
// Bbecomes…:
```lang=typescript
module mw {
interface metricsPlatform {
submit( instrumentName: string, event: EventRecord<string, any> ): void;
}
}
```
