IContentExtractorContentExtractionHeartbeat Event

Notification event that lets implementers of IContentExtractor know that content extraction is still under process. See remarks.

Namespace: OpenDiscoverSDK.Interfaces.Extractors
Assembly: OpenDiscoverSDK.Interfaces (in OpenDiscoverSDK.Interfaces.dll) Version: 2025.4.4.0 (2025.4.4)

Syntax

Copy

event LongRunningContentExtractionHeartbeat ContentExtractionHeartbeat

Value

LongRunningContentExtractionHeartbeat

Remarks

Some file formats that contain huge amounts of text, document pages, or worksheets can take a while to extract content. This event handler is fired periodically in these special cases to notify IContentExtractor implementers that content extraction is still underway (and not a "zombie" or hung process).

It is up to the user to unsubscribe from this event once content extractor use is finished.
