How to Speed Up Non-Version Time Series Database?

A non-version time series database is a database, which stores only actual time series data and metadata. Such time series database has no information about changes in series data and metadata, which were previously made.

TIP. How to understand whether a time series database is version or non-version?
Time series database is version, if its properties on theAttributespage contains the Keep Version History checkbox selected. By default, the checkbox is selected, it can be deselected only when creating a time series database.

If the time series database was created in Prognoz Platform 8.1 or earlier, it can be sped up due to system index optimization. To execute optimization, use the IRubricator.AlterAndSave method.

NOTE. If a non-version time series database was created in Prognoz Platform 8.2 or later, its system indexes are already optimized for maximum performance.

Fore Example

Executing the example requires that the repository contains a non-version time series database with the TSDB identifier created in Prognoz Platform 8.1 or earlier.

Add links to the Cubes, Metabase system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    TSDB: IRubricator;
Begin
    // Get time series database
    mb := MetabaseClass.Active;
    TSDB := mb.ItemById("TSDB").Edit As IRubricator;
    // Check if database is a version one
    If Not TSDB.KeepHistory Then
        // If time series database
        // is a non-version one, optimize it
        TSDB.AlterAndSave;
    End If;
End Sub UserProc;

After executing the example system indexes of time series database are optimized.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with that in the Fore example.

Imports Prognoz.Platform.Interop.Cubes;
…
Public Shared Sub Main(Params: StartParams);
Var
    mb: IMetabase;
    TSDB: IRubricator;
Begin
    // Get time series database
    mb := Params.Metabase;
    TSDB := mb.ItemById["TSDB"].Edit() As IRubricator;
    // Check if database is a version one
    If Not TSDB.KeepHistory Then
        // If time series database
        // is a non-version one, optimize it
        TSDB.AlterAndSave();
    End If;
End Sub
