|
This driver is suitable for the most abstract (and thus universal) case.
|
|
The driver does not have any built-in services nor node discovery
|
|
capabilities. All services need to be listed explicitly in a config file.
|
|
Node list is specified using `node_list` node discovery driver.
|
|
|
|
**Example of multi-node configuration:**
|
|
|
|
Note that in this configuration a node discovery driver is required.
