h3. Discovery all Plexus components

Once the ClassRealm is populated with the plugin artifact and its dependency artifacts a discovery operation must be performed on the plugin ClassRealm in order to discover any Plexus components that may be present in any of the artifacts required for the plugins execution.

h3. Looking up the plugin with a configuration

#### 3.2 Public Prometheus config

If Prometheus endpoint authentication type is set to `public`. Following prometheus config is sufficient to start scraping metrics data from MinIO.
This can be collected from any server once per collection.

##### Cluster

```yaml
scrape_configs:
- job_name: minio-job
  metrics_path: /minio/v2/metrics/cluster
  scheme: http
  static_configs:
  - targets: ['localhost:9000']
```

	dst   chan []jstream.KVS // result of block decode

}

// Read - reads single record.
// Once Read is called the previous record should no longer be referenced.
func (r *PReader) Read(dst sql.Record) (sql.Record, error) {
	// If we have have any records left, return these before any error.
