DataSource

batchBoolean(default: false)

If set to true, the data source will batch CRUD operation requests. For example, updating two data items would cause one HTTP request instead of two. By default, the data source makes an HTTP request for every CRUD operation.

The changed data items are sent as models by default. This can be changed via the parameterMap option.

Example - enable the batch mode 

<script>
var dataSource = new kendo.data.DataSource({
  batch: true,
  transport: {
    read:  {
      url: "https://demos.telerik.com/service/v2/core/products"
    },
    update: {
      url: "https://demos.telerik.com/service/v2/core/products/update",
      type: "POST",
      contentType: "application/json",
    }
  },
  schema: {
    model: { id: "ProductID" }
  }
});
dataSource.fetch(function() {
  var product = dataSource.at(0);
  product.set("UnitPrice", 20);
  var anotherProduct = dataSource.at(1);
  anotherProduct.set("UnitPrice", 20);
  dataSource.sync(); // causes only one request to "https://demos.telerik.com/service/v2/core/products/update"
});
</script>
