<pre>
Output only. The number of replica hours used. Note that many replicas may
run in parallel, and additionally any given work may be queued for some
time. Therefore this value is not strictly related to wall time.

<code>double replica_hours = 1 [(.google.api.field_behavior) = OUTPUT_ONLY];</code>

@return The replicaHours.
