Item filtering

Description

This transformation is applicable to models that contain collection of "items" (e.g. variables). Dfs2, Dfs3, netcdf files typically contain one or more items (such as temperature, sea surface height and so on), but also datasets in the Multidimensional storage have items. The transformation allows to select only a subset of these items for further processing (e.g during export from Multidimensional storage to a file).

This request to /api/conversion/upload-convert

var transferResult = await transferClient

            .WithItemFilteringTransformation(0, 1, 2)
            ...
            .ExecuteAsync();

will only select the first three items from the source file. Other forms of filtering (e.g. by name) will be implemented on request (or self-service).
