implements PriorityOrBuilder
     Priority contains metadata that controls relative ordering of task processing
 when tasks are backed up in a queue. Initially, Priority will be used in
 matching (workflow and activity) task queues. Later it may be used in history
 task queues and in rate limiting decisions.

 Priority is attached to workflows and activities. By default, activities
 inherit Priority from the workflow that created them, but may override fields
 when an activity is started or modified.

 Despite being named "Priority", this message also contains fields that
 control "fairness" mechanisms.

 For all fields, the field not present or equal to zero/empty string means to
 inherit the value from the calling workflow, or if there is no calling
 workflow, then use the default value.

 For all fields other than fairness_key, the zero value isn't meaningful so
 there's no confusion between inherit/default and a meaningful value. For
 fairness_key, the empty string will be interpreted as "inherit". This means
 that if a workflow has a non-empty fairness key, you can't override the
 fairness key of its activity to the empty string.

 The overall semantics of Priority are:
 1. First, consider "priority": higher priority (lower number) goes first.
 2. Then, consider fairness: try to dispatch tasks for different fairness keys
    in proportion to their weight.

 Applications may use any subset of mechanisms that are useful to them and
 leave the other fields to use default values.

 Not all queues in the system may support the "full" semantics of all priority
 fields. (Currently only support in matching task queues is planned.)

      • getPriorityKey

        public int getPriorityKey()
         Priority key is a positive integer from 1 to n, where smaller integers
 correspond to higher priorities (tasks run sooner). In general, tasks in
 a queue should be processed in close to priority order, although small
 deviations are possible.

 The maximum priority value (minimum priority) is determined by server
 configuration, and defaults to 5.

 If priority is not present (or zero), then the effective priority will be
 the default priority, which is is calculated by (min+max)/2. With the
 default max of 5, and min of 1, that comes out to 3.
        int32 priority_key = 1;

      • getFairnessKey

        public java.lang.String getFairnessKey()
         Fairness key is a short string that's used as a key for a fairness
 balancing mechanism. It may correspond to a tenant id, or to a fixed
 string like "high" or "low". The default is the empty string.

 The fairness mechanism attempts to dispatch tasks for a given key in
 proportion to its weight. For example, using a thousand distinct tenant
 ids, each with a weight of 1.0 (the default) will result in each tenant
 getting a roughly equal share of task dispatch throughput.

 (Note: this does not imply equal share of worker capacity! Fairness
 decisions are made based on queue statistics, not
 current worker load.)

 As another example, using keys "high" and "low" with weight 9.0 and 1.0
 respectively will prefer dispatching "high" tasks over "low" tasks at a
 9:1 ratio, while allowing either key to use all worker capacity if the
 other is not present.

 All fairness mechanisms, including rate limits, are best-effort and
 probabilistic. The results may not match what a "perfect" algorithm with
 infinite resources would produce. The more unique keys are used, the less
 accurate the results will be.

 Fairness keys are limited to 64 bytes.
        string fairness_key = 2;
        Specified by:
        getFairnessKey in interface PriorityOrBuilder
        Returns:
