task_id；The task status of the task task_id got is updated in processing, according to state machine to task task_id's
The monitored results of task status execute the processing operation to match with the task status of task task_id to task task_id.
It should be noted that those skilled in the art it can be appreciated that refer to the characteristics of an idempotent operation in programming
It is identical as the influence once executed that generated influence is arbitrarily performed a plurality of times in it.Idempotent function or idempotent method, referring to can be with
It is repeated using identical parameters, and the function of identical result can be obtained.These functions do not interfere with system mode, without load
The heart, which repeats, to be caused to change to system.Therefore, the idempotence of task refers to that task is arbitrarily performed a plurality of times to be produced in the present invention
Raw influence is identical as the primary execution influence of task.
In a preferred embodiment, the step of judging whether to store the task in first database described in step 101,
It specifically includes：According to the unique identification information of the task, judge the task whether is cached in the caching of first database.
Wherein, the step of creating the task in the first database described in step 102, specifically includes：By institute
The task of stating is written in the caching of the first database.
Wherein, the task status include create, in processing, handle successfully and processing failure.
For example, in the task processes of asynchronous service A, the task with unique identification information is received, such as unique mark
Know the task that information is task_id and then according to the unique identification information task_id of the task, judges first database, such as
MySQL, caching in whether cache task task_id；If uncached, task task_id is created in MySQL, and by task
Task_id is written in the caching of MySQL, and the visioning procedure of task task_id is with reference to figure 3.
Through this embodiment, it to realize that the reliability consumption of task provides necessary precondition, avoids first
When being stored with the waiting task received in database, the feelings for creating the already present task are repeated in first database
Condition occurs, and the resource of system has been saved, to improve the treatment effeciency of task.

Breath.
For example, in the task processes of asynchronous service A, the task with unique identification information is received, such as unique mark
Know the task that information is task_id and then according to the unique identification information task_id of the task, judges first database, such as
MySQL, tables of data in be stored with task task_id, then return to the mission bit stream of task task_id by MySQL, such as appoint
The unique identification information task_id of business task_id already present notification information and task task_id.
In another example for example, in the task processes of asynchronous service A, the task with unique identification information is received, such as
Unique identification information is that the task of task_id then according to the unique identification information task_id of the task, judges the first data
Library, such as MySQL, caching in be stored with task task_id, then the mission bit stream of task task_id is returned by MySQL,
Such as the unique identification information task_id of the already present notification informations of task task_id and task task_id.
In a preferred embodiment, the task is inserted into the task queue of the second database by step 104, when receiving
When the processing request of the task, the task is obtained from the task queue by task treatment progress, including：It will be described
Task is inserted into the task queue of the second database, and returns to the task successfully created by the first database
Mission bit stream；When the processing for receiving the task is asked, the task based on the task that the first database returns
Information obtains the task by task treatment progress from the task queue of the second database.
Wherein, the task queue of second database is the queue based on atomic operation.
For example, in the task processes of asynchronous service A, the task with unique identification information is received, such as unique mark
Know the task that information is task_id then to store task task_id to first database, in MySQL, task is set
The task status of the initialization of task_id passes through task task_id in state machine monitors MySQL if task status is to create
Task status then task task_id is written in the caching of MySQL, and by task task_id the second data of radom insertion
Library, such as Redis, any task queue in, and the mission bit stream of task task_id successfully created is returned to by MySQL,
When the processing for receiving task task_id is asked, based on the mission bit stream of the MySQL task task_id returned, pass through task
Treatment progress obtains task task_id from the task queue of Redis.
It should be noted that those skilled in the art are it can be appreciated that atomic operation refers to a service logic to be
Or the failure of can not be split or successful execution does not execute completely.Those skilled in the art will also be appreciated that the present invention is real
It is the queue based on atomic operation to apply the queue in the Redis databases in example, and the realization method of atom queue has more clocks, this hair
Though bright can illustrate by taking the realization method of specific atom queue as an example, do not limit herein.
In a preferred embodiment, this method further includes：Task queue cluster is pre-created in second database；In advance
Establishment task treatment progress cluster.
Wherein, described when the processing for receiving the task is asked, based on described in first database return
The mission bit stream of business obtains the task by task treatment progress from the task queue of the second database, including：Work as reception
To the task processing request when, judge whether to receive the mission bit stream for the task that the first database returns,
The processing request of the task includes the unique identification information of the task；If receiving, institute in being asked according to the processing
The unique identification information for stating task is counted by any task treatment progress in the task treatment progress cluster from described second
According to obtaining the task in the task queue cluster pre-created in library；If not receiving, appoint according to described in processing request
The unique identification information of business, it is pre- from second database by the task treatment progress cluster based on predetermined acquisition frequency
The task is obtained in the task queue cluster of establishment.
For example, pre-creating task queue cluster M in the second database Redis, task queue cluster M includes multiple
Task queue, such as task queue 1, task queue 2 and task queue 3；Pre-create task treatment progress cluster, including multiple tasks
Treatment progress, as using Stark (be one as multi-process finger daemon in order to run the program library of PHP code) cluster,
Including Stark1 and Stark2；In the task processes of asynchronous service A, when the processing for receiving task task_id is asked
When, judge whether the mission bit stream for receiving the task task_id that the first database MySQL is returned, task task_id's
Processing request includes the unique identification information task_id of the task；If receiving the mission bit stream of the task task_id of return
When, according to the unique identification information task_id of task task_id, by any task treatment progress in Stark clusters, such as
Stark1 obtains task task_id from the task queue cluster M pre-created in Redis；If not receiving the task of return
When the mission bit stream of task_id, according to the unique identification information task_id of task task_id, frequency is obtained based on predetermined, such as
0.01 second/time of acquisition frequency obtains task by Stark clusters from the task queue cluster M pre-created in Redis
task_id.The flow diagram of task is obtained from task queue cluster with reference to the task treatment progress cluster in figure 4.
Through this embodiment, high-performance and the Stark distributed consumers model of Redis queues are utilized to greatest extent to carry
The performance of high system, to dramatically realize the high-performance of task consumption.
In a preferred embodiment, the task status of the task got is updated in processing by step 105, according to
State machine matches to the task status of the task execution and the task to the monitored results of the task status of the task
Processing operation, including：The task status of the task got is updated in processing, is in processing to task status
The callback operation of the task execution task, and whether the callback operation for monitoring the task is more than scheduled time threshold；If
It is more than to be based on predetermined operation agreement, the task execution task is adjusted back.
Wherein, described that the task execution task is adjusted back, including：Step A judges to adjust back the task execution task
Whether succeed；If readjustment failure, is updated to processing failure, and based in predetermined operation agreement by the task status of the task
Number is adjusted back, the task execution task is adjusted back again, redirects and executes step A, until readjustment number reaches the predetermined behaviour
Make the readjustment number in agreement or returns successfully；If adjusting back successfully, the task status of the task is updated to handle successfully, and tie
Processing of the beam to the task.
For example, in the task processes of asynchronous service A, when task treatment progress cluster has been obtained such as Stark clusters
After the mission bit stream for getting task task_id, the task status of the task task_id got is updated in processing, it is right
Task status is the callback operation of the task task_id execution tasks in processing, such as adjusts back the corresponding business of task task_id and connects
The operation of mouth, and whether the callback operation of monitor task task_id is more than scheduled time threshold, such as 5 minutes；If more than predetermined
Time threshold 5 minutes, be based on predetermined operation agreement, such as reach an agreement with business side for when the callback operation of task is more than to make a reservation for
Time threshold when, execute the agreement of 1 callback operation again to the task, then, task readjustment executed to task task_id
Operation, and judge to execute whether task readjustment succeeds to task task_id, if readjustment failure, by the task shape of task task_id
State is updated to processing failure, and based on the readjustment number 1 time in predetermined operation agreement, executes task to task task_id again
Readjustment；If adjusting back successfully, the task status of task task_id is updated to handle successfully, and terminates the place to task task_id
Reason.The processing procedure of task is with reference to figure 5.
In a preferred embodiment, further include that task repairs queue, root described in step 105 in the task queue cluster
According to state machine to the monitored results of the task status of the task, to the task status phase of the task execution and the task
The step of processing operation matched, further include：There are appoint in scheduled duration in by state machine monitors to the first database
When business state is continuously the first task of establishment, the first task is inserted into the task in second database and repairs team
Row, to complete the establishment of the first task；There are in scheduled duration in by state machine monitors to the first database
When task status is continuously the second task in processing, second task is inserted into the task and repairs queue, to complete
State the processing of the second task.
Wherein, the scheduled duration is more than the predetermined time span for obtaining the unit interval in frequency.For example, pre- timing
Between the section time span that is be 10 minutes, then make a reservation for obtain the time span of the unit interval of frequency and be less than 10 minutes.
For example, in the task processes of asynchronous service A, there is pre- timing in by state machine monitors to MySQL
