Overview

This release Significantly extends the functionality provided for Cube Analytics by hiperspace and combines streaming recalculation with graph navigation. The cube enhancement is detailed on OLAP use-case. To support Cube analytics and code-generation for aggregation service, and a number of additions were made to Hipersapce and HiLang compiler.

Blazor enhancements

This release removes obsolete functions that are no longer used, such as Space() which has been replaced by ExportAsync() to provide a streaming transfer of updates from a SessionSpace for higher performance.

SetSpace

The Bind function now has an addition parameter for read/write so that filter can be used to delete elements without the need to open an additional connection

SubSpace

In addition to ExportAsync and ImportAsync, SubSpaces now include ExportCacheAsync and ImportCacheAsync to allow a server gRPC endpoint to select all the elements that are needed for a use-case and send them all in one message to the client.

BrowserSpace

This new type of space has been created in order to address the limitations of blazer web assembly that does not support synchronous network IO. BrowserSpace will be deprecated once WebAssembly support asynchronous threads.

Browser space, any synchronous operation, uses only the local changes cache, while asynchronous operations use either the local cache or the remote store

A matching change has been made to the HiLang code generator to use the local BrowserSpace for synchronous operations while

Cube Changes

CubeFact property on an Element, now has a mathcing ICubeFact inteface and ICubeDrillDown for drill-down to further levels of detail
CubeHierarchy property identifies a CubeDimension that is a hierarchy, with a reference to the member key/value that provides the parent. This results in as ICubeHierarchy<> interface added to the dimension element
DeltaIndex property now results in a IDeltaIndex<> element added to RefSet<> for the elements SubSpace collection, to retrieve all values that have changed since the timestamp. This interface is used by the Hiperspaced.Meta.Route map to retrieve all elements that have changed since the last calculation
ElementVersion<> now allows the AsAt property to be changed by an application to allow the historical data loading of a Hiperspace for Cube Analytics
Additional functions added for drilldown() (from cube to details) cubename() (for Graph name of a cube observation) contextlabel() (use context when retrieving cubes there might be separate summaries for P&L and implied P&L )
SetSpace<> now has an additional event OnMissing that allows missing cube aggregates to be calculated on-demand, or fetched from an external database

The change also includes updates to referenced assemblies
