@paul-griffith,  
For the conversion from Ignition 7.9.10 of :

```auto
gatewayContext.getTagManager().queryHistory

```

with BasicTagHistoryQueryParams and BasicStreamingDataset

could you please provide an example for :

```auto
context.getTagHistoryManager().getTagHistoryProvider(<name>).createQuery(paths, controller)

```

**I don’t understand how to achieve an historical query from gateway scope in Ignition 8** 🆘

HistoryQueryExecutor javadoc indicate that the result rows are writed to the streaming dataset, if possible but where can we provide a streaming dataset to the createQuery function or params ???

Ignition 7.9

```auto
gatewayContext.getTagManager().queryHistory()

```

is replaced in Ignition 8.0 by :

```auto
gatewayContext.getTagHistoryManager().queryHistory

```
