MatcherHandler

The Matcher service provides an interface for matching jobs to pilots

It uses a Matcher and a Limiter object that encapsulates the matching logic. It connects to JobDB, TaskQueueDB, JobLoggingDB, and PilotAgentsDB.

class DIRAC.WorkloadManagementSystem.Service.MatcherHandler.MatcherHandler(handlerInitDict, trid)

Bases: MatcherHandlerMixin, RequestHandler

__init__(handlerInitDict, trid)

Constructor

Parameters:

• handlerInitDict (dictionary) – Information vars for the service

• trid (object) – Transport to use

auth_ping = ['all']
