> The first `insert` request.

> Above is what fetched vertex looks like when storage backend is `AsynchbaseStorage`, but `RocksStorage` gives different vertex.
> {noformat}
> {
> 	"id": 1,
> 	"props": {
> 		"is_active": false, // default value
> 		"phone_number": "abcdefg",
> 		"nickname": "..", // default value.
> 		"age": 0 // default value.
> 	}
> }
> {noformat}
> Note that `is_active` give default value instead of first value user inserted(the second request overwrite the first request).
> Suggest to fix `RocksStorage` to behave like `AsynchbaseStorage`.
