Abstract
The invention discloses a task concurrent processing method in a workflow system, comprising the following steps: S1, receiving task input of an input channel; and S2, screening the received task input to finish the implementation of a task in multiple same tasks concurrent input. The task concurrent processing method of the invention ensures that one task is finished by only one input channel through adding the screening step when the task is processed; and other same inputs are thrown exceptionally, thus shortening the throwing exception waiting time of the input channel, and improving the task processing efficiency.
Description
Technical field
The present invention relates to the workflow processing technical field, task concurrent processing method in particularly a kind of Workflow system.
Background technology
Along with the expansion gradually of Workflow system range of application, a lot of Workflow systems begin to be deployed in the middle of some high load capacities, the high concurrent application system, and this just makes Workflow system raise gradually for high load capacity, high concurrent requirement.The all very low or poor user experience of efficient that most of commercial pursuit streaming systems are handled for task in this high load capacity, the high concurrent scene on the market now.Because task handling is accomplished by an input, a task can have a plurality of input channels, but can only be accomplished by an input channel.The mode that following two kinds of Processing tasks are arranged at present:
1, as shown in Figure 1; When a plurality of inputs are concurrent when handling; Certain input is if accomplished task earlier, and other input will be dished out because task has been done unusually, but because the task handling process is very very long sometimes; Just can get access to for a long time unusually so input can be waited for, cause the exception response overlong time of system;
2, as shown in Figure 2, if Workflow system adopts single-threaded Processing tasks to avoid the generation of this problem, will let all inputs all can rank, handling one by one causes the task treatment effeciency to reduce.
Summary of the invention
The technical matters that (one) will solve
The technical matters that the present invention will solve is: in the Workflow system that requires high concurrent, high load capacity, how to reduce the unusual stand-by period of dishing out of input channel, improve the task treatment effeciency simultaneously.
(2) technical scheme
Task concurrent processing method in a kind of Workflow system may further comprise the steps:
S1: input channel receives the input of task;
S2: the input to the task of receiving is screened, and makes a task in a plurality of same task of concurrent input complete.
Wherein, screening mode is following among the said step S2:
Whether the state of checking this task is completion status, if it is unusual then to dish out,
Otherwise if the input of this task is to make task accomplish the input of type, the state that then writes down and preserve this task is a completion status, and handles the said input that makes task accomplish type, the completion status of this task of back deletion of finishing dealing with; If the input of this task is the input of interim treatment type, then stage is carried out in the input of this stage treatment type and handle, and add the interim record of handling.
Wherein, When if same task has the input of a plurality of interim treatment type; The interim real-time status of handling of logger task, this moment, the state that then writes down and preserve this task was a completion status if receive the input that makes task completion type; And handle the said input that makes task accomplish type, the completion status of this task of back deletion of finishing dealing with.
Wherein, said input channel is the multi-thread concurrent passage.
Wherein, adopt single-threaded channel screen.
(3) beneficial effect
The present invention guarantees each task only by an input channel completion through when task is handled, adding the screening step, and other identical input is then dished out unusually, has reduced the unusual stand-by period of dishing out of input channel, has improved the task treatment effeciency.
Description of drawings
Fig. 1 is the method synoptic diagram of concurrent processing task traditional in the Workflow system;
Fig. 2 is the method synoptic diagram of the single-threaded Processing tasks of Traditional use in the Workflow system;
Fig. 3 is a task concurrent processing method synoptic diagram in a kind of Workflow system of embodiments of the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
As shown in Figure 3, be task concurrent processing method synoptic diagram in a kind of Workflow system of embodiments of the invention.The input of the task that input channel is received at the execution row filter that advances, makes a task in a plurality of same task of concurrent input complete.Wherein input has two types input, and a kind of is to make task accomplish the input of type, has promptly carried out each stage or the step of task; Another kind is the input of task being carried out interim treatment type, has only carried out or implemented wherein certain stage or step.Above-mentioned two kinds of inputs are all received by the multi-thread concurrent passage.Among Fig. 3, have two tasks 1 to be transfused to, top task 1 is accomplished the input of type for making task; Following task 1 is for the input of interim treatment type or make task accomplish the input of type; When screening, realize, to distinguish arriving in two very short times of being separated by of task, because top task 1 is carried out earlier through screening through single-threaded passage; So following task 1 is in time dished out unusually, has saved unusually and has dished out the time.
Concrete screening process is following:
Whether the state of checking this task is completion status, if it is unusual then to dish out,
Otherwise if this task is to make task accomplish the input of type, the state that then writes down and preserve this task is a completion status, and handles the input that this makes task completion type, the completion status deletion of this task that will before preserve after finishing dealing with; If this task is the input of interim treatment type, then stage is carried out in the input of this stage treatment type and handle, and add the interim record of handling, be i.e. the interim real-time status of handling of logger task.
Same task can have a plurality of interim processing to import simultaneously simultaneously, but an input that task is accomplished can only be arranged, and must in the end handle.When if same task has the input of a plurality of interim treatment type; The interim real-time status of handling of logger task, this moment, the state that then writes down and preserve this task was a completion status if receive this task of input that makes task completion type; And handle this and make task accomplish the input of type; If the input of identical task is arranged again, it is unusual then to dish out in the time of in processing procedure, the completion status deletion of this task that will before preserve after the completion.
Specifically give an example with one below the present invention be described:
As: a phone call for appeal is got to 10086 mobile customer services, says that phone can't breathe out the task of a handling problem of customer service program creation.
If backstage personnel one have A, B, C, four treatment peoples of D, seen this task simultaneously, wherein:
A carries out phase process, " whether inquiring about this user telephone fee uses up "
B has carried out accomplishing processing, " this user telephone fee uses up, and please point out the user to supplement with money "
C has carried out accomplishing processing, " this user telephone fee uses up, and please point out the user to supplement with money "
D carries out phase process, " whether inquiring about this user telephone fee uses up "
Because A, B, C and D are in this task of processing, therefore above-mentioned B and C have handled the step of be over " whether inquiring about this user telephone fee uses up ".
Four people submit to simultaneously, and input channel receives four inputs simultaneously, promptly concurrent input, and the order when screening is ABCD.At this moment; A can be let slip by screening; B also can be let slip and logger task sign by screening, and expression has received the input that task is accomplished type, C can dish out because task identification exists unusual (task is processed); D also can dish out because task identification exists unusual (task is processed), and finally this task is accomplished by B.Handle the input of B screening back, and as Query Information is sent to the client, after the input of B finished dealing with, this task had also just been finished dealing with.The task identification of deletion precedence record after task is finished dealing with.
The present invention is particularly suitable in high concurrent, the Workflow system that the preemptive type task is handled.
