I am trying to connect to a datastore that needs different parameters to retrieve the data. I've tried different multiple instances of the data connector - but data studio seems to struggle to store different configuration values? The Data Connector control isn't currently available for community connectors. What's the best approach please ?
Community Connectors currently do not support parametrization. We have plans to add this feature in the future. At present, other than dates, you cannot pass parameters to the connector while viewing the dashboard.
You can add the same connector multiple times as separate data sources using different configurations or you can edit the current data source and change the parameters (under Manage data sources).
