Discovery Service Connectors
The discovery service connectors contain the implementation of the discovery services provided by Egeria.
Sequential Discovery Pipeline - Runs nested discovery services in a sequence. More information on discovery pipelines.
CSVDiscoveryService - Extracts the column names from the first line of the file, counts up the number of records in the file and extracts its last modified time..
Discovery services are responsible for analysing the content of assets and creating
descriptions of its content (called Annotations).
The annotations from a top-level discovery service execution are grouped together and linked from the asset as a discovery analysis report. They run in the Asset Analysis OMES.
Once the discovery service has completed its analysis, an event is sent by the Governance Engine OMAS to any listening Engine Host OMAG Servers running the Governance Action OMES to process the results.
The interfaces used by a discovery service are defined in the Open Discovery Framework (ODF) along with a guide on how to write a discovery service.
