18

|
|
|
|
|
|
|
Helios::MetajobBurstService is a subclass of Helios::Service specially tasked with bursting |
20
|
|
|
|
|
|
|
metajobs. You can subclass this class to provide special metajob bursters for your application. |
21
|
|
|
|
|
|
|
This allows you more fine grained control over the volume of jobs entering the Helios job queue. |
22
|
|
|
|
|
|
|
|
23
|
|
|
|
|
|
|
A MetajobBurstService class supports one config parameter, burst_interval, which is the |
24
|
|
|
|
|
|
|
number of seconds between metajob bursts. This is to prevent the metajob bursting process from |
25
|
|
|
|
|
|
|
running so fast the Helios job queue is overwhelmed with burst jobs. |
