    Syntax

    Remarks

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

    When RealtimeTableDefinition.HasTrackIDField is true, it represents total number of rows within each track.

    When RealtimeTableDefinition.HasTrackIDField is false, it represents total number of rows.

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

    It uses FIFO method - the first one comes in is the first one to be removed.
