Performance Issues with multi row selection

$

Hey!

 

I have a custom visual with a process graph, in this graph I can select edges and filter the graph to only show processes with this specific edge.

I'm using a Table DataViewMapping and I am creating my selection IDs with this Code:

function getSelectionIds(dataView: DataView, host: IVisualHost): ISelectionId[] {
        return dataView.table.identity.map((identity: DataViewScopeIdentity) => {
            const categoryColumn: DataViewCategoryColumn = {
                source: dataView.table.columns[1],
                values: null,
                identity: [identity]
            };

            return host.createSelectionIdBuilder()
                .withCategory(categoryColumn, 0)
                .createSelectionId();
        });
    }

If I have a selection in my graph I am getting all selected rows selectionIds and pass them to the selection manager as an array.

 // Select all cases with the specific edge in their path
                    for (i = 0; i < viewModel.eventlogData.length; i++) {
                        if (viewModel.eventlogData[i].path.search(id_from + "::" + id_to) >= 0) {
                            selectionIdArray.push(viewModel.eventlogData[i].selectionID);
                        }
                    }

                    selectionManager.select(selectionIdArray, true);
                    selectionManager.applySelectionFilter();

The creation of this selectionIdArray is not the problem, it only takes a few ms, but I looks PowerBI will get slower (up to 2 min for 1500 rows/elements in the array) the more selectionIds I pass.

 

Is there a better/faster way to multiselect multiple rows? 

 

All help is kindly appreciated!
