SAP Lumira Data Access Extension SDKs – Version 1 vs Version 2

This is a short blog post to give you a clear picture of the two versions of the Data Access Extension(DAE) SDKs we currently support in SAP Lumira. If you are starting to develop a new data access extension, we recommend you to use the Version 2 SDK. The following table will give you a better idea of the new features that we support with the V2 SDK,

Feature Version 1 DAE SDK Version 2 DAE SDK
Lumira releases supported v 1.17 and above v 1.25 and above
Selecting an extension Extension present inside the External Data Source option Extension is listed along with the native connectors seamlessly
Activation in SAPLumira.ini file Required Not Required
Extension Manager Installation support No Yes
Server installation support No Yes
Versioning No Yes
Extension UI Windows Native(doesn’t blend with Lumira!!) SAP UI5/other JS libraries(blends well with Lumira!!)
Deployment Executable, Manually copied to a specific local folder Zip file, Installed with the Extension Manager
Programming language (backend) Any language, compiled to an executable Java
Programming language (UI) Has to be handled by the executable SAP UI5/ any JS library
Data Preview screen One default screen with a table, Handled by Lumira Can develop custom Preview UI screens, ex: tree view for JSON, etc.
Prepare room column import defaults No control. Lumira tries to set some defaults Complete control over importing columns specifically into Dimensions, Measures, set Aggregation types for measures, group columns into custom hierarchies
Runtime debugging support No Yes. Chrome dev console for UI, Remote Java VM debugging inside Eclipse

Hope this helps you better understand the differences between these two versions. Please leverage the new features we offer with the Version 2 SDK and develop new data access extensions with it. We have a sample extension for you to get started,
