```
public class JdbcSeedNodeProviderConfig
extends Object
```
Configuration for JdbcSeedNodeProvider.
Database structure

By default the following database table should exist in the target database:
```
 CREATE TABLE cluster_nodes (
      namespace VARCHAR,
      host VARCHAR,
      port NUMBER
 )
 
```
It is possible to modify table and column names by using the following properties:
- setTable(String) - table name (default is "cluster_nodes")
- setNamespaceColumn(String) - column to store cluster namespace (default is "cluster_namespace")
- setHostColumn(String) - column to store host address (default is "host")
- setPortColumn(String) - column to store port value (default is "port")
Database connectivity

Database connectivity is controlled by the following properties:
- setDataSource(DataSource) - JDBC datasource to be used for obtaining database connections
- setQueryTimeout(int) - optional timeout value for SQL queries (see Statement.setQueryTimeout(int))
