QOS (venice API)

java.lang.Object
- java.lang.Enum<QOS>
- - com.linkedin.alpini.consts.QOS

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<QOS>
```
public enum QOS
extends java.lang.Enum<QOS>
```
Sets the quality of service (QOS) for the request. A request with a high QOS will be serviced preferentially over a low QOS. Assigning backend and batch jobs a low QOS will help keep high priority frontend requests responsive, even when these batch jobs are running.

    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (QOS c : QOS.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static QOS valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
