Referring to fig. 2, fig. 2 is a functional module schematic diagram of a distributed data center according to an embodiment of the present invention.
In this embodiment, the data center based on the distributed deployment architecture includes: one background trading node 10, and a plurality of customer trading nodes 20. The background transaction node 10 is a server installed with a background transaction system, and the client transaction node 20 is a server installed with a client transaction system.
Wherein a position synchronization device 30 is provided in each customer trading node 20. Each client trading node 20 performs position synchronization processing with the background trading node 10 through the position synchronization device 30, and the position synchronization device 30 communicates with the background trading node 10 through a message bus mode.
In this embodiment, the background transaction node 10 is configured to receive the position flow and reconciliation request sent by the position synchronization device 30, execute a reconciliation process corresponding to the reconciliation request, and return a reconciliation process result.
In this embodiment, when position stream synchronization is performed, in order to ensure the correctness of the synchronized position stream, the account checking is performed one by one, so as to ensure that the position stream of each pen of the synchronization initiator (the client transaction node 20) is synchronized to the receiver (the background transaction node 10); and then batch reconciliation is carried out, so that the synchronous position flow received by the synchronous receiving party (the background trading node 10) is ensured to be consistent with the position flow in the initiating party (the client trading node 20), and all the position flow of each client trading node is ensured to be normally synchronized to the remote background trading node through the one-by-one reconciliation and the batch reconciliation, and the position synchronization is ensured to be correct in two directions.
Based on the hardware structure, the invention provides various embodiments of the position synchronization method in the distributed environment.
Referring to fig. 3, fig. 3 is a schematic flow chart of a position synchronization method according to an embodiment of the present invention. In this embodiment, the position synchronization method includes the following steps:
step S10, in the position synchronization, sending the first position flow which is not synchronized and not checked in the selected customer trading nodes to the background trading nodes, and requesting the background trading nodes to check the first position flow one by one;
in this embodiment, because the position flow generated on each customer transaction node 20 is large and dynamically changed, that is, the position flow of each pen on the customer transaction node 20 cannot be synchronized to the background transaction node 10 at one time, the position synchronization is performed in a multi-round manner, and a small amount of position flow is synchronized in each round, for example, each round synchronizes 100 pen positions.
In this embodiment, the position synchronization is expressed not only in the transfer of data but also in the correctness of the transferred data. To ensure the accuracy of synchronization of the position flow from the client transaction node 20 to the background transaction node 10, the present embodiment specifically performs reconciliation to achieve the following objectives:
the purpose is as follows: ensuring that all position streams of the synchronous initiator are sent to the receiver;
purpose two: ensuring that all the position streams received by the receiver are consistent with the position stream of the initiator.
In this embodiment, in one round of position synchronization, the position synchronization device 30 sends the unsynchronized and unpattemed first position flow (including a plurality of different position flows) in the selected customer transaction node 20 to the background transaction node 10, and requests the background transaction node 10 to perform one-by-one account checking on the first position flow, so as to achieve the above-mentioned purpose.
In this example, the reconciliation one by one specifically means that the background transaction node 10 reconciles the received running water of each pen tip one by one according to a certain sequence, and the specific manner and content of reconciliation are not limited, for example, the generation time, running items, running amount, and the like of the running water of each pen tip are collated, and a reconciliation result of the running water of each pen tip is generated.
Step S20, receiving the item-by-item reconciliation result returned by the background trading node, and updating the synchronization state and the reconciliation state of the first dimension flow in the client trading node based on the item-by-item reconciliation result;
in this embodiment, the position synchronization device 30 receives the item-by-item reconciliation result returned by the background transaction node 10, and updates the synchronization state and the reconciliation state of the first position flow in the client transaction node 20 based on the item-by-item reconciliation result. For example, the synchronization status is changed from unsynchronized to synchronized, and the reconciliation status is changed from unpattemed to successful.
Step S30, batch reconciliation is carried out on a second position flow which is synchronized and successfully reconciled in the client transaction node to obtain a first batch reconciliation result, a background transaction node is requested to carry out batch reconciliation on the second position flow, and a second batch reconciliation result returned by the background transaction node is received, wherein the first position flow comprises the second position flow;
step S40, judging whether the first batch reconciliation result is different from the second batch reconciliation result;
step S50, if yes, an alarm is sent to the outside;
and step S60, if not, determining that the synchronization of the second position stream from the customer trading node to the background trading node is completed.
In this embodiment, the second position flow synchronized and successfully checked in the customer transaction node already satisfies the first purpose, so to further achieve the second purpose, this embodiment specifically adopts a batch checking mode, and specifically includes:
firstly, the position synchronization device 30 performs batch reconciliation on a second position flow which is synchronized and successfully reconciled in the customer transaction node 20 to obtain a first batch reconciliation result;
secondly, the position synchronization device 30 requests the background transaction node 10 to perform batch reconciliation on the received second position flow, and receives a second batch reconciliation result returned by the background transaction node 10;
in this embodiment, the batch reconciliation mode is not limited, for example, the reconciliation is collected for all position streams, and the position synchronization device 30 can determine whether the position synchronization has achieved the second objective by comparing whether the batch reconciliation results of the two are different.
If the first batch of reconciliation results are different from the second batch of reconciliation results, sending an alarm, and further checking and eliminating faults through manual intervention; if the first batch reconciliation result is not different from the second batch reconciliation result, the second position flow simultaneously meets the first aim and the second aim, namely the synchronous bidirectional correctness of the position flow from the client trading node 20 to the background trading node 10 is ensured.
In this embodiment, when position stream synchronization is performed, in order to ensure the correctness of the synchronized position stream, account checking is performed one by one, so as to ensure that the position stream of each pen of the synchronization initiator (client transaction node) is synchronized to the receiver (background transaction node); and then batch reconciliation is carried out, so that the synchronous position flow received by the synchronous receiving party (background trading node) is ensured to be consistent with the position flow in the initiating party (client trading node), and all the position flow of each client trading node is ensured to be normally synchronized to the remote background trading node through the one-by-one reconciliation and the batch reconciliation, and the position synchronization is ensured to be correct in two directions.
Optionally, in another embodiment of the position synchronization method of the present invention, the itemized reconciliation result specifically includes the following three types of situations:
the first situation is as follows: the account checking result by one account is matched with the corresponding position running water in the first position running water
In such a case, the position synchronization device 30 updates the synchronization state and the reconciliation state of the position running water corresponding to the one-by-one reconciliation result in the first position running water to be synchronized and the reconciliation is successful, respectively;
case two: the account checking result by one account is not in accordance with the corresponding position running water in the first position running water
In such a case, the position synchronization device 30 updates the synchronization state and the reconciliation state of the position running water corresponding to the one-by-one reconciliation result in the first position running water to unsynchronized and unpaired;
case three: the account result of the item-by-item reconciliation is null, that is, the background transaction node 10 does not return the account result of the item-by-item reconciliation
Under such a situation, the position synchronization device 30 adds the position running water corresponding to the situation in the first position running water into the next position synchronization, so as to continue position synchronization until the position running water achieves real synchronization, that is, until the synchronization state and the reconciliation state of the position running water are respectively updated to be synchronized and the reconciliation is successful.
In addition, in another embodiment, in order to avoid the abnormal event in the synchronization process from affecting the synchronization efficiency, therefore:
optionally, the position synchronization device 30 monitors whether a position flow exists in the customer transaction node 20, where the synchronization state is in synchronization execution or not, and the synchronization state duration time exceeds a preset time duration, and if the position flow exists, sends an alarm to the outside, for example, notifies an operation and maintenance worker of manual intervention.
Further optionally, in an embodiment of the position synchronization method of the present invention, in step S30: the position synchronization device 30 performs batch reconciliation on the second position flow which is synchronized and successfully reconciled in the customer transaction node, and specifically comprises the following steps:
step S1, when the position flow of the synchronized reconciliation success in the customer transaction node reaches the preset batch reconciliation reference, generating a new global reconciliation code;
and step S2, taking the position running water corresponding to the batch reconciliation reference as a second position running water and associating the second position running water with the reconciliation code, and performing pad difference processing on the second position running water associated with the reconciliation code.
In this embodiment, to ensure that the position synchronization device 30 and the background transaction node 10 unify the reconciliation standard when performing batch reconciliation, a batch reconciliation standard is preset, for example, a preset time length is used as the batch reconciliation standard, or a preset position running water amount is used as the batch reconciliation standard.
In this embodiment, a global account checking code is specifically set for association, and one account checking code corresponds to a stream of multiple positions. For example, taking 100 pen inches of running water as a batch reconciliation standard, and setting a reconciliation code to be associated with the 100 pen inches of running water; or taking the position running water generated within one hour as a batch reconciliation reference, and setting a reconciliation code to be associated with the position running water generated within the one hour.
Optionally, the position synchronization device 30 further requests the background transaction node 10 to perform the offset processing on the position flow associated with one account checking code to obtain a first batch of account checking results, and at the same time, further requests the background transaction node 10 to perform the offset processing on the position flow associated with the same account checking code to obtain a second batch of account checking results, and finally determines to complete the synchronization of the second position flow associated with the account checking code from the client transaction node 20 to the background transaction node 10 by comparing whether the first batch of account checking results and the second batch of account checking results are different, and if not, automatically marks that the position flow associated with the account checking code has successfully completed batch account checking.
And obtaining related summary information of the second position running water corresponding to the account code through the difference rolling processing, such as total income amount, expenditure amount, total payment voucher information and the like. If the same multi-position running is subjected to multiple rolling differences respectively, the obtained summary information is bound to be the same, if the obtained summary information is different, the position running corresponding to the different rolling differences is different, and based on the difference, the method can be used for judging whether the position running received by the background trading node 10 is consistent with the position running in the initiator (the client trading node 20).
The present invention also provides a computer-readable storage medium applied to the position synchronization apparatus.
The computer-readable storage medium has stored thereon a position synchronization program which, when executed by a processor, performs the steps of any of the embodiments of the position synchronization method described above.
Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal (such as a mobile phone, a computer, a server, an air conditioner, or a network device) to execute the method according to the embodiments of the present invention.
