How to TWebIndexedDbClientDataset ?

Hi ,

Trying to learn how to use TWebIndexedDBClientDataset , if my existing code has an
open TWebClientDataset , how can i get my data in my TWebClientDataset
into the TwebIndexedDBClientDataset ?

Can i load the TwebIndexedDBClientDataset with data after the request ?
i.e. webIndexedDBClientDataset1.Rows := TJSArray(TJSJSON.parseObject(_data));

What are the use of KeyFieldName and ObjectStoreName ?
Is there any reference so i can learn how to use this new component ?
