fig. 2 is a schematic flow chart illustrating a detailed flow of a method for controlling a delay triggered transaction according to a second embodiment of the present invention.
Detailed Description
In order to better and clearly show the technical scheme of the invention, the invention is further described with reference to the attached drawings.
The technical personnel in the field understand that, aiming at the defects of the prior art, the invention discloses a control method of delayed trigger transaction, which can manage a plurality of transactions needing delayed trigger and start a specific delayed trigger transaction when the trigger time is reached. Through the technical scheme provided by the invention, a plurality of delay trigger transactions can be managed in order to form an independent management mechanism.
Fig. 1 is a schematic flow chart illustrating a control method for a delay triggered transaction according to a first embodiment of the present invention. Specifically, the method comprises the following steps:
first, the process proceeds to step S101, and transaction request information is received. Those skilled in the art understand that, preferably, for the control device and the control method provided by the present invention, only the transaction request information that needs to be triggered by a delay time is sent to the control device provided by the present invention, and is further processed by the embodiments shown in fig. 1 and fig. 2. Thus, upon receipt of one or more transaction request messages, the control means preferably proceeds directly to initiate subsequent processing steps, such as step S102, step S103, etc. In another variation, all transaction request messages are sent to the control device, but not every transaction request message is a time-delay triggered transaction, so the control device also needs to perform screening, as described below. Furthermore, in another variation, all the transaction request information is first sent to a general control system, and the general control system filters all the transaction requests and forwards the transaction request information with the delay triggering requirement to the control device. Such variations are within the scope of the present invention and are not described herein.
Then, step S102 is executed to adaptively store the transaction request information and the trigger time information corresponding to the transaction request information in a cache. For transaction request information with a delayed trigger requirement, the control device preferably stores the transaction request information in a cache, and the transaction request information is reserved for subsequent continuous processing. Specifically, in this embodiment, the transaction request information and the trigger time information corresponding to the transaction request information are adaptively stored in the cache, that is, when the transaction request information and the trigger time information are stored, the trigger time information corresponding to each transaction request information is stored together, for example, this is a timestamp, as shown in the embodiment shown in fig. 2. Those skilled in the art will appreciate that upon the arrival of the trigger time, the transaction request message will preferably be initiated for execution, thereby accomplishing the objects of the present invention.
And finally, step S103 is executed, wherein a monitor polls all trigger time information in the cache, and when a certain trigger time expires, an instruction for processing the transaction request information is issued. After all the transaction request messages are stored in the cache, in this step, all the transaction request messages are polled, for example, a polling monitor that executes in a loop is started, all the transaction request messages in the cache are queried, whether the corresponding transaction request messages should be executed is determined by the trigger time corresponding to each transaction request message, and if the trigger time expires, that is, the current time (machine time or server time) of the polling monitor is consistent with the trigger time corresponding to the transaction request message, or the trigger time corresponding to the transaction request message exceeds the current time, the transaction request messages are preferably started to execute. Accordingly, once a transaction request message is executed, it is preferably removed from the cache, i.e. it does not need to be managed with a delay trigger.
Further, those skilled in the art will understand that, in both the embodiment shown in fig. 1 and the embodiment shown in fig. 2, the transaction request information is preferably stored in a cache and deleted from the cache after the transaction request information is executed, so as to make efficient use of the cache and facilitate management. Those skilled in the art understand that the transaction request information may be managed by various technical means, for example, the transaction request information is preferably managed by sequencing in a queue manner, and the transaction request information may also be managed by using a stack, a tree structure, a database structure, a text manner, and the like, which are within the scope of the present invention and will not be described herein again.
Further, it is understood by those skilled in the art that, in one variation, after the control device receives a transaction request message, the following steps are performed:
i. judging whether the transaction request information can be processed in a delayed way;
if the transaction request information can be processed in a delayed manner, executing the step S102 in FIG. 1; if the transaction request information can not be processed in a delayed manner, the transaction request information is directly processed, and the subsequent steps shown in fig. 1 are not executed. Those skilled in the art will appreciate that in such a variation, not every received transaction request message has a delayed trigger attribute, so the control device determines whether the transaction request message has a delayed trigger time or similar attribute tag, and then determines whether to perform the processing of step S102 and subsequent steps shown in fig. 1.
Further, in another preferred embodiment, the step S103 can be implemented by: and adaptively storing the transaction request information and trigger time information corresponding to the transaction request information in a Redis ordered set. In such an embodiment, a Redis ordered set is established in the cache, and the transaction request information is managed via the Redis ordered set. Further, those skilled in the art understand that the Redis ordered set is only one implementation way for managing the transaction request information, and the transaction request information can be easily ordered by the Redis ordered set with a proper ordering key value, so that polling becomes simpler, popularization is easy, and the work efficiency of the computer processing system is improved.
Continuing the thought of the Redis ordered set, further preferably, the step related to the Redis ordered set may further include the following steps: and storing the transaction request information in a Redis ordered set by taking the unique identifier of the transaction request information as a Key. Further, those skilled in the art will understand that, since the unique identifier of the transaction request information has uniqueness, the unique identifier can be used as an index of the Redis ordered set or a similar key, and similar variations are within the scope of the present invention and will not be described herein.
Continuing the thought of the Redis ordered set, further preferably, the step related to the Redis ordered set may further include the following steps: and sequencing the Redis ordered set by taking the trigger time stamp corresponding to the transaction request information as a sequencing basis. In this embodiment, each transaction request information in the Redis ordered set is sorted by using the trigger time information of each transaction request information, preferably expressed as a transaction request information trigger time stamp as a sorted key value, and when there is a plurality of transaction request information with consistent timestamp information, the transaction request information does not need to be sorted together in order. In other variations, all transaction request information in the Redis ordered set or similar containers (e.g., queues, databases) may be sorted in other manners, which is within the scope of the present invention and will not be described herein.
On the basis of the embodiment shown in fig. 1, fig. 2 is a schematic flow chart showing a control method for delayed triggered transaction according to a second embodiment of the present invention.
In particular, those skilled in the art will appreciate that after the transaction request messages are stored in the cache, the transaction request messages need to be monitored to initiate one or more transaction request messages when triggered by a delay. The process of polling all trigger time information in the cache by a monitor may be performed by:
c1. inquiring all trigger time information in the Redis ordered set through a timer;
c2. and temporarily sending an instruction for processing the corresponding transaction request information at a certain trigger time.
Specifically, those skilled in the art understand that, in order to not miss any transaction request information, the timer should monitor all transaction request information in real time, for example, a common practice is to use a continuous loop monitor to perform polling query on all transaction request information in the cache or the Redis ordered set, and similar variations are within the protection scope of the present invention and are not described herein again.
Correspondingly, if the delay trigger time corresponding to a certain transaction request message arrives, the transaction request message is directly processed, that is, the transaction request message is started, or the transaction request message is sent to the main process to be queued for processing, and similar variations are also within the protection scope of the present invention and are not described herein again.
Further, those skilled in the art will appreciate that the monitor may be implemented by a specific process, for example, the process may be initiated once every 60 seconds, and may be polled for 60 seconds each time, so as to continuously poll all transaction request information, which will not be described herein.
More specifically, referring to the embodiment shown in fig. 2, step S201 is first executed, and polling is started from the first piece in the corresponding set, and the first piece of transaction request information is taken as the current transaction request information. Those skilled in the art will appreciate that the corresponding set, i.e. the set storing the transaction request information, may exist in any form, and such variations are within the scope of the present invention and are not described herein. Preferably, the query is initiated from the first transaction request message of the set. Further, those skilled in the art understand that, in the case of the sorted set, the first transaction request information record is usually the transaction request information closest to the current time, and is not described herein again.
Secondly, step S202 is carried out, when the trigger time stamp corresponding to the current transaction request information is less than or equal to the current time stamp, an instruction for processing the corresponding transaction request information is sent out based on the unique identifier of the transaction request information, and the transaction request information is deleted from the set; otherwise, executing the next step, and taking the next transaction request information as the current transaction request information. Once the triggering timestamp corresponding to the current transaction request information is less than or equal to the current timestamp in the polling process, the triggering timestamp indicates that the current transaction request information has reached the triggered time, and then the transaction request information is executed. When the control device cannot execute the transaction request information, an instruction for executing the transaction request information is sent to a corresponding main control system, such as a main CPU, and the like, which is not described herein again.
Further preferably, since the current transaction request information is already executed, it is not necessary to monitor the current transaction request information, and the transaction request information is deleted from the cache or any one of the sets of managed transaction request information, and similar variations are within the protection scope of the present invention and are not described herein again.
Finally, step S203 is executed, and when the trigger timestamp corresponding to the current transaction request information is greater than the current timestamp, the first transaction request information in the corresponding set is used as the current transaction request information, and polling is restarted. When the trigger timestamp corresponding to the current transaction request information is greater than the current timestamp, it indicates that the current transaction request information and the subsequent transaction request information have not reached the trigger time yet, so polling is started again from the first transaction request information in the cache, and the cycle is repeated until no transaction request information exists in the cache.
With reference to the embodiment shown in fig. 1 and fig. 2, those skilled in the art will understand that, correspondingly, in other embodiments of the present invention, there is also provided a control device for delayed triggered transaction, which is characterized by comprising the following devices:
first receiving means for receiving transaction request information;
first storage means for adaptively storing the transaction request information and trigger time information corresponding to the transaction request information in a cache;
and the first processing device is used for polling all the trigger time information in the cache through a monitor and sending out an instruction for processing the corresponding transaction request information when a certain trigger time expires.
