30000 row limit

Hi All,

I'm pretty new to Power BI, but I have been asked by a client to investigate the use of the 3rd party "HierarchySlicer" visualization.

That particular visualization has a built-in data record limit of 4000 (by using the dataReductionAlgorithm code).

I can tweak the number specified in the code to be a larger number, but no matter how high I set it, I am only ever getting back a maximum of 30,000 records.

The client has more than 30,000 records in the data set they wish to show in the slicer.

I also followed a simple tutorial to create a quick slicer visulization of my own, but I'm hitting the exact same 30,000 row limitation.

"dataViewMappings": [
        {
            "categorical": {
                "categories": {
                    "for": {
                        "in": "fields"
                    },
                    "dataReductionAlgorithm": {
                        "top": {
                            "count": 500000
                        }
                    }
                }
            }
        }
    ],

Is this something that can be worked around, or is there an alternative way of getting all the required data to show?

Does the same limitation apply if/when the dashboard is published?

Many thanks, and apologies if this is duplicating queries...
