getPersistData without the data ( dataSourceSettings.dataSource )

Question

We use getPersistData in the Pivot table in order to persists its settings. We do not need the data though as it might become very large with 100k records or so.

Is it possible to fetch everything return by getPersistData but without the data array (dataSourceSettings.dataSource ) .

I understand we can remove it but, if does not need to be processed by the getPersistData method it might be faster and more efficient.

Thank you

Hi Thierry,Using dataBound and load event, you can save
and load the report from localStorage instead of using getPersistData. Please
refer the below code example. Code Example:

dataBound: function (args) {
      if (pivotObj) {
        obj = 'PivotTable' + pivotObj.element.id;
        var pivotTableObj = JSON.parse(
          document.querySelector('#PivotView').ej2_instances[0].getPersistData()
        );
        if (pivotTableObj) {
          pivotTableObj.dataSourceSettings.dataSource = [];
        }
        localStorage[obj] = JSON.stringify(pivotTableObj);
      }
    },
    load: function (args) {
      obj = 'PivotTable' + pivotObj.element.id;
      if (obj && localStorage[obj]) {
        var data = JSON.parse(localStorage[obj]);
        data.dataSourceSettings.dataSource =
          pivotObj.dataSourceSettings.dataSource;
        pivotObj.dataSourceSettings = data.dataSourceSettings;
      }
    },
