This section details a selection of advanced features of the SparkSQL adapter.
User Defined Views
The adapter allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.
Use SSL Configuration to adjust how adapter handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.
Firewall and Proxy
Configure the adapter for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.
See Logging for an overview of configuration settings that can be used to refine CData logging. For basic logging, you only need to set two connection properties, but there are numerous features that support more refined logging, where you can select subsets of information to be logged using the LogModules connection property.
