Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The following description will be made of specific contents of examples.
An embodiment of the present invention provides a transaction concurrency control method, and referring to fig. 1, is a flowchart of a transaction concurrency control method provided in an embodiment of the present invention, where the method includes:
s101: after a transaction processing request of any account is received, whether the account exists in a preset hotspot account table is inquired, and if yes, S102 is executed.
S102: and judging whether the transaction concurrency amount currently processed by the account reaches the maximum value of the concurrency amount of the account, if so, executing S102 in a circulating mode at a preset frequency, and if not, executing S103.
S103: processing the next transaction processing request for the account is initiated.
In the embodiment of the invention, after receiving a transaction processing request of any account, the system inquires whether the account belongs to a hotspot account or not in a preset hotspot account table for storing hotspot accounts. And if the account belongs to the hotspot account, controlling the transaction concurrency amount of the account. And if the account does not belong to the hotspot account, directly processing the transaction processing request of the account.
In practical applications, the hot account is generally an account with a higher transaction concurrency in a certain time, for example, an account with a transaction concurrency of up to 500 times in a one second in a banking system. The embodiment of the invention can count the transaction concurrency of each account in the system within the preset time in advance, and obtain the account with the transaction concurrency meeting the preset condition as the hot spot account, and store the hot spot account as the hot spot account table of the system. In addition, the hot account in the hot account table can be updated along with the change of the hot account, so as to represent the current latest situation of the system.
In the embodiment of the invention, after the system determines that the account is the hotspot account, the transaction concurrency amount of the account is controlled. Specifically, whether the transaction concurrency amount currently processed by the account reaches the maximum value of the concurrency amount of the account is judged. If the maximum amount of concurrency for the account is not reached, the system may process the next transaction processing request for the account.
And if the system determines that the transaction concurrency amount currently processed by the account reaches the maximum value of the concurrency amount of the account, the system delays for preset time and then re-executes to judge whether the transaction concurrency amount currently processed by the account reaches the maximum value of the concurrency amount of the account. And so on, until the system determines that the currently processed transaction concurrency amount of the account has not reached the maximum concurrency amount of the account, the next transaction processing request of the account cannot be processed.
That is, the system may not process the next transaction processing request until the transaction concurrency amount of the account is not saturated. If the transaction concurrency amount of the account reaches the saturation, the system waits for a period of time and then judges whether the transaction concurrency amount of the account reaches the maximum value of the concurrency amount again. And after a plurality of times of waiting and judgment again, the system controls the transaction concurrency of the account.
In the embodiment of the invention, after receiving a transaction processing request of any account, the system firstly inquires whether the account exists in a preset hot account table, and if so, the account is determined to be the hot account. Secondly, whether the transaction concurrency amount currently processed by the hotspot account reaches the maximum value of the concurrency amount of the account is judged. If so, circularly executing the judgment on the currently processed transaction concurrency amount of the account at a preset frequency until the currently processed transaction concurrency amount of the account is determined not to reach the maximum concurrency amount. Eventually beginning to process the next transaction processing request for that account. In summary, the embodiment of the present invention avoids the problem that a large amount of system resources are occupied due to a large transaction concurrency amount of the hotspot account by controlling the transaction concurrency amount currently processed by the hotspot account.
An embodiment of the present invention further provides a transaction concurrency control method, and referring to fig. 2, fig. 2 is a flowchart of another transaction concurrency control method provided in the embodiment of the present invention. The method comprises the following steps:
s201: after receiving a transaction processing request of any account, querying whether the account exists in a preset hotspot account table, if so, executing S202.
S202: and judging whether the queuing to-be-processed transaction amount of the account reaches the preset queuing maximum value of the account, if not, executing S203, and if so, executing S205.
S203: and judging whether the currently processed transaction concurrency amount of the account reaches the maximum value of the concurrency amount of the account, if so, executing S203 in a circulating mode at a preset frequency, and if not, executing S204.
S204: processing the next queued pending transaction processing request for the account is commenced.
S205: suspending receipt of transaction processing requests for the account.
In the embodiment of the invention, the system allocates a single transaction concurrency control thread for each hotspot account respectively. After the system receives a transaction processing request of any hotspot account, the control thread of the hotspot account firstly judges whether the queuing to-be-processed transaction amount of the account reaches a preset queuing maximum value. If the queued pending transaction of the account has reached the maximum queuing value, it indicates that the account cannot receive a new transaction processing request, i.e. the transaction processing request of the account is suspended from being received, and the user is prompted.
And if the queuing transaction amount to be processed of the account does not reach the queuing maximum value, the control thread of the account continuously judges whether the currently processed transaction concurrency amount of the account reaches the concurrency amount maximum value of the account. And if the currently processed transaction concurrency amount of the account reaches the maximum value of the concurrency amount of the account, circularly judging whether the currently processed transaction concurrency amount of the account reaches the maximum value of the concurrency amount by the control thread of the account at a preset frequency. Once it is determined that the concurrency level maximum has not been reached, the system may begin processing the next queued pending transaction processing request for the account.
In the embodiment of the invention, after receiving a transaction processing request of a hotspot account, a system firstly judges whether the queuing to-be-processed transaction amount of the account reaches the preset queuing maximum value of the account, and judges whether the currently processed transaction concurrency amount of the account reaches the concurrency amount maximum value of the account when the queuing to-be-processed transaction amount of the account does not reach the queuing maximum value. And if the transaction concurrency amount currently processed by the account reaches the maximum concurrency amount, circularly judging whether the transaction concurrency amount currently processed by the account reaches the maximum concurrency amount or not at a preset frequency. Upon determining that the currently processed transaction concurrency amount for the account does not reach the concurrency amount maximum, processing of a next transaction processing request for the account is initiated. The embodiment of the invention achieves the purpose of controlling the transaction concurrency amount by judging the queued transaction amount to be processed of the hotspot account and the currently processed transaction concurrency amount, and finally avoids the problem that a large amount of system resources are occupied due to huge transaction concurrency amount of the hotspot account.
