) 

Parameters

The System.TimeSpan indicating rows older than this value will be removed.
Exceptions
ExceptionDescription

Remarks

You need to set SetExpirationMethod to RowExpirationMethod.MaxAge to get that in effect.

When RealtimeTableDefinition.HasTrackIDField is true, it represents maximum age within each track. Previous observations that are older than the maximum expiration age comparing to the latest observation in the same track, will be removed.

When RealtimeTableDefinition.HasTrackIDField is false, rows older than the maximum expiration age, comparing to the current time, will get removed.

If you don't want any rows removed, set this value to 0.

Requirements

Target Platforms: Windows 10, Windows 8.1, Windows 7
