ConnectionFactoryOptions (Reactive Relational Database Connectivity

java.lang.Object
- io.r2dbc.spi.ConnectionFactoryOptions

```
public final class ConnectionFactoryOptions
extends Object
```
A holder for configuration options related to ConnectionFactorys.
A ConnectionFactoryOptions represents a configuration state that consists of one or more Option objects. Each configuration option can be specified at most once to associate a value with its key.
New objects are constructed through builder() or by parsing a R2DBC Connection URL. ConnectionFactoryOptions can be augmented to allow staged construction of the configuration state using a initialized builder to create a new ConnectionFactoryOptions objects with mutations applied. Values of this class are immutable once created. Builder initializers are left unchanged.
Example usage:
```
 ConnectionFactoryOptions options = ConnectionFactoryOptions.builder()
     .option(ConnectionFactoryOptions.DRIVER, "a-driver")
     .option(ConnectionFactoryOptions.PROTOCOL, "pipes")
     .option(ConnectionFactoryOptions.HOST, "localhost")
     .option(ConnectionFactoryOptions.PORT, 3306)
     .option(ConnectionFactoryOptions.DATABASE, "my_database")
     .option(Option.valueOf("locale"), "en_US")
     .build();
 
```
