IRubricator.KeepHistory

Syntax

KeepHistory: Boolean;

Description

The KeepHistory property determines whether to keep history of time series changes for the time series database.

Comments

Available values:

True. The changes history is kept, that is, the time series database is a version one. The default value when a time series database is created.
False. The changes history is not kept. If the time series database includes large amount of data, disabling versions optimizes database performance.

To correctly convert a version time series database into a non-version one, compress all the revisions into one using the IRubricatorInstance.CutRevisions method. If revisions are not compressed, transformation into non-version mode is disabled.

Example

The property use is given in the example for IRubricator.HasMnemonics.
