Prisma 5.0 `$use` Middleware Alert Scoping to Specific Datasource

Goal

Configure Prisma 5.0 `$use` middleware so that alerts fire only when query failures or specific patterns occur on a designated datasource, while routine query logs remain silent.

Constraints

• Handlers must be asynchronous but avoid heavy work that delays query execution.
• Access to the full query payload is required for filtering by `event.kind` or error flags.
• Alerts should be scoped to a single datasource without affecting other instances.

Uncertainty

The current design lacks a native alerting hook, leaving the choice between `$use` and external triggers unresolved.

Questions

1. Can `$use` be ordered to guarantee payload availability without impacting performance?
2. Is it possible to filter events by datasource directly within `$use` without additional logic?
3. Does Prisma provide a native alert hook that could replace external implementation?
