Configuration

We must configure our Worker. Common definitions must be defined in config.yml file, setting values for all installed Workers. Also we must config gearman cache, using doctrine cache.

Note

If iterations value is 0, worker will not kill itself never, so thread will be alive as long as needed. The reason to allow workers to kill themselves is just to prevent each process to accumulate a large quantity of memory.

         # If any include is defined, Only these namespaces will be parsed
         # Otherwise, full Bundle will be parsed

   # This is useful if you don't have an "AppBundle"

   # default values
   # All these values will be used if are not overwritten in Workers or jobs
   defaults:

      # If empty, 0 is defined by default
      iterations: 150

      # Default amount of time in seconds required for the execution to run.
      # This is useful if using a tool such as supervisor which may expect a command to run for a
      # minimum period of time to be considered successful and avoid fatal termination.
      # If empty, no minimum time is required
      minimum_execution_time: null

      # Default maximum amount of time in seconds for a worker to remain idle before terminating.

   # Server list where workers and clients will connect to
   # Each server must contain host and port
   # If annotations defined, will be full overwritten
   #
   # If servers empty, simple localhost server is defined by default
   # If port empty, 4730 is defined by default

In development mode you do not want to cache things over more than one request. An easy solution for this is to use the array cache in the dev environment ( Extracted from DoctrineCacheBundle documentation )
