ForAll + Patch can be one approach to Batch update the database. However, be careful in using the order of For All and Patch.

Following function:
The following Patch() inside a ForAll() loop creates multiple individual requests that execute one after another in sequence, which results in slow performance.

```powerappsfl
Patch(SampleFoodSalesData, ForAll(colSampleFoodSales,
{
demoName:"fromCanvas2"
})
ForAll( colSampleFoodSales,
Patch( SampleFoodSalesData,
{ demoName: "test" }
)
);
```

Performs better than:
Instead of patching individual records inside a loop, pass the entire collection to Patch() in a single operation. These updates happen in parallel, significantly improve performance.

```powerappsfl
ForAll(colSampleFoodSales, Patch(SampleFoodSalesData,
{
demoName:"test"
})
Patch( SampleFoodSalesData,
ForAll( colSampleFoodSales,
{ demoName: "fromCanvas2" }
)
);
```
