Embodiment
Set forth a lot of detail in the following description so that fully understand the application.But the application can be much different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the application's intension, and therefore the application is by the restriction of following public concrete enforcement.
The application provides a kind of deals match method, and in addition, the application also provides a kind of deals match system.
A kind of embodiment of deals match method is as follows:
Embodiment one
With reference to Fig. 2, it illustrates the present embodiment and a kind of deals match method processing flow chart is provided.
Described in the present embodiment, deals match method comprises the following steps:
S201; The transaction receiving user's submission is preengage and is stored into reservation databases.
Receive the transaction that user submits to described in this step to preengage and be stored into reservation databases and performed by reservation processing cluster.Described transaction is preengage real-time storage in reservation databases after receiving the transaction reservation of user's submission by reservation processing cluster.
Described reservation processing cluster comprises multiple servers, and any station server in the middle of this reservation processing cluster all can perform above-mentioned processing procedure.
S202; Read transaction reservation from reservation databases, business processing is carried out to described transaction reservation, and exports after being converted into trading order form.
In above-mentioned steps S201, completed by described reservation processing cluster and reservation databases process has been stored in described transaction reservation.In this step, when reservation processing cluster processes described transaction reservation, in the middle of described reservation databases, first read described transaction reservation; Secondly business processing is carried out to described transaction reservation and form trading order form; Finally described trading order form is exported.A corresponding transaction reservation, generates one or strokes trading order form.
S203; Receive described trading order form, and this trading order form is inserted in the first message-oriented middleware.
Described first message-oriented middleware comprises queue first and retry queue;
Wherein, the retry set of queues that is made up of multiple retry queue of described retry queue; The quantity of described retry queue is determined according to the overstocked number of trading order form in the middle of retry queue.
Queue in the middle of described first message-oriented middleware also comprises priority and arranges, and specifically arranges as follows:
The priority of described retry queue is determined according to the number of retries of trading order form in the middle of retry queue, and the retry queue priority that described number of retries is larger is also higher.
Described queue first and the retry global precedence effect level order to team is as follows:
Retry queue n> ... > retry queue 2> retry queue 1> queue first.
In addition, described first message-oriented middleware can also adopt the set of queues outside the present embodiment to realize, and the priority setting of described queue also can adopt the method outside the present embodiment to realize, in this no limit.
S204; Trading order form is read from described first message-oriented middleware.
Described matching treatment cluster reads according to the priority orders of queue in the middle of described first message-oriented middleware when reading described trading order form from the first message-oriented middleware, and the preferential trading order form read in the middle of the higher queue of priority.
S205; From working memory, find the product that current matching needs most, and read the product data of this product.
Described working memory needs the product data of product for storing matching process.
Before find the product that current matching needs most from working memory, comprise the following steps:
1) from product database, read the product collection of Vehicles Collected from Market model adaptation;
Described product collection derives from product database, and is the product data that current matching needs most, and the full dose product data of described product collection not necessarily in product database, only represent the portioned product data that current matching needs most.Described product data comprise product category, product quantity and various product ratio.
Further, described product category, product quantity and various product ratio configure according to current market model (comprising: buyer's market model, seller's market model, equilibrium market model).
Such as:
A, under the model of buyer's market, the buyer in the middle of both parties is in leading status, and the product that the seller provides is more, and the demand of the buyer is less, and within considerable time, the product provided of the seller cannot consume by the buyer completely.
Now, can increase the quantity that described working memory loads product, that is: the product quantity of described product collection, is configured to maximum, as 100,000 by the quantity of described product collection.
In addition, also can, by the ratio of various product in the middle of the described product collection of configuration, product content be made to meet the purchase application of most user as much as possible.The main purchase application Dou Shi bank series products of the such as current buyer, then increase the ratio of bank's series products in the middle of described product collection, to promote the success ratio of coupling, so the proportioning of product in the middle of described product collection may be:
Mechanism's product: 10%; P2P product 10%; Bank product 75%; Other products 5%.
B, under the model of seller's market, the seller in the middle of both parties is in leading status, and the buyer is a lot, and the product that the seller provides is little, once the seller provides product, will have been consumed in a short time by the buyer.
Now, the product quantity of described product collection can be reduced, the quantity of described product collection is configured to 40,000.
In addition, configure described product collection according to the market pattern of product as far as possible, do enough consumptions to ensure that various product can obtain.Such as, the proportioning of product is:
Mechanism's product: 5%; P2P product 60%; Bank product 25%; Other products 10%.
C, under equilibrium market model, both parties are at equilibrium.
Now, the configuration of product collection is trended towards to the intermediateness of above-mentioned buyer's market model and seller's market model, even, configure described product collection according to the marketing strategy of business.Such as, the proportioning of product is:
Mechanism's product: 10%; P2P product 50%; Bank product 10%; Other products 30%.
In the present embodiment, described product collection configures according to different market models, thus make described product energy collecting enough farthest meet the product of user for the demand of product and simultaneously reasonably under consumption Vehicles Collected from Market model, support described distributed transaction matching system business processing under multiple market model.
2) memory partitioning of various product and working memory in the middle of described product collection is stored in the middle of memory partitioning according to one-to-one principle;
Described working memory is divided into different memory partitionings to store described product collection, such as: the mechanism's product in the middle of product collection, P2P product, bank product and other products, according to the principle of the corresponding series products in memory partitioning, and to be stored in the middle of each self-corresponding memory partitioning.
After completing the Data Preparation of above-mentioned two steps, enter searching product and reading product data process of this step.
B+ tree is adopted to set up index to product, with the product that fast finding is relevant; Certainly, the indexing means using other is not got rid of yet.
B+ tree is a kind of data tree structure, is generally used in the file system of database and operating system.The feature of B+ tree to keep data stabilization orderly, and it inserts and has more stable logarithmic time complexity with amendment.B+ sets element bottom-up insertion, and this and binary tree are just the opposite.
Node in B+ tree is represented as one group of orderly element and sub-pointer usually.If the ordinal number (order) that this B+ sets is m, then each node except root comprises the maximum m-1 of a minimum m/2 element element, has maximum m sub-pointer for arbitrary node.For all non-leaf nodes, the number of sub-pointer always more than the number of element one.
The element of each non-leaf nodes serves as the separation value of separately its subtree.Such as, if non-leaf nodes has three child nodes (or subtree), then it must have two separation values (a1, a2); Values all in the subtree on the left side is all less than a1, and values all in middle subtree is all between a1 and a2, and values all in the subtree of the right is all greater than a2.
The mode of searching of B+ is similar to binary tree search, originates in root node, top-down traverse tree.When searching, if the key value in non-leaf nodes equals the desired value that will inquire about, do not stop inquiry, but continue downwards until leafy node.Therefore, in B+ tree, no matter search success or not, search is all walked a path from root node to leafy node at every turn.
B+ is adopted to set the operational data test comparison of searching the mode of searching of mode and common traversal as follows:
| Product quantity list | Common traversal searches unit/in the least | B+ tree searches unit/millisecond |
| 10000 | 4981.54 | 1894.237 |
| 20000 | 1677.428 | 139.346 |
| 30000 | 2196.821 | 164.908 |
| 40000 | 3881.273 | 141.766 |
| 50000 | 3907.733 | 129.441 |
| 60000 | 4866.081 | 135.001 |
| 70000 | 5356.214 | 145.497 |
| 80000 | 6052.107 | 128.189 |
| 90000 | 7694.815 | 135.467 |
| 100000 | 7411.704 | 126.357 |
The algorithm complex that common traversal is searched is O [], and the complexity of B+ tree algorithm is O [log
2n], the query time based on the mode of searching of common traversal is linear increase substantially as can be seen from upper table also, and the query time that B+ tree searches mode is progressively stabilized in a minimum value, there is not the situation of linear increase.In addition, in actual applications, can according to expected yield, product issuing time, product type, production life cycle, the data such as the minimum purchase share of product are set up B+ and are set index, easy-to-look-up.
It should be noted that, above-mentioned working memory, product integrate, the implementation method of market model and index search as a kind of preferred implementation of the application, in addition, the method outside the present embodiment all can be adopted to realize, in this no limit.
S206; Described trading order form is mated with described product.
The product data that the trading order form read according to above-mentioned steps S204 and step S205 read, both products that described trading order form is corresponding with described product data mate; Described coupling meets time priority principle and price priority principle.
S207; Judge that whether described coupling is successful.
If the match is successful, then enter step S208;
If it fails to match, then enter following steps:
Judge whether the matching times of described trading order form exceedes maximum permissible value;
If described matching times exceedes maximum permissible value, then described trading order form is rejected in the middle of described transaction queue;
If described matching times does not exceed maximum permissible value, then described trading order form is proceeded in the middle of the more higher leveled transaction queue of priority from current transaction queue.
The object arranging the maximum permissible value of matching times is in order to avoid the wasting of resources.In deals match process, sometimes have the trading order form that some conditions are harsh especially, these trading order forms cannot obtain the product on sale matched all the time; And according to the prioritization schemes of this match trading system, this trading order form can obtain very high priority level, like this, will cause match trading system is constantly these trading order form input coefficient resources, but cannot produce and obtain coupling achievement, for this reason, this deals match system pre-sets the maximum permissible value of coupling, as the criterion whether continuing as a certain trading order form input coefficient resource.If exceed this maximum permissible value, then reject this trading order form to save system resource.
S208; Described trading order form is converted to result order, and this result order is inserted into the second message-oriented middleware.
The processing procedure of this step is performed by matching treatment cluster, and the processing procedure of above-mentioned steps S204 to S207 performs by matching treatment cluster.
Described matching treatment cluster comprises multiple servers, and the processing procedure of above-mentioned steps S204 to S207 and this step all can perform handled by any station server in the middle of this matching treatment cluster.
S209; From described second message-oriented middleware, read result order, business processing is carried out and outgoing traffic result to described result order.
Described second message-oriented middleware be implemented as a result queue, described result queue comprises multiple result order, each result order is as a message of the second message-oriented middleware, and described second message-oriented middleware meets first in first out and possesses the function of initiatively PUSH.
It is as follows that described result order carries out business procession:
1) result treatment cluster receives the trading instruction for described trading order form that user sends;
Described result treatment cluster comprises multiple servers, and described trading order form can perform handled by any station server in the middle of this result treatment cluster.
2) corresponding operation is performed according to described trading instruction, outgoing traffic result.
Such as: user agrees to described result order, and by the instruction placed an order be committed in the middle of described match trading system; Described deals match system performs respective operations according to described lower single instrction, and proceeds to payment step, and completes the payment to described result order.After completing the business processing to described result order, the service processing result of described result order is stored in transaction data base.

Mechanism's product: 5%; P2P product 60%; Bank product 25%; Other products 10%.
3) under equilibrium market model, both parties are at equilibrium.
Now, the configuration of product collection is trended towards to the intermediateness of above-mentioned buyer's market model and seller's market model, even, configure described product collection according to the marketing strategy of business.Such as, the proportioning of product is:
Mechanism's product: 10%; P2P product 50%; Bank product 10%; Other products 30%.
In the present embodiment, described product collection configures based on market model, thus make described product energy collecting enough farthest meet the product of user for the demand of product and simultaneously reasonably under consumption Vehicles Collected from Market model, support the business processing of described distributed transaction matching system under multiple market model.
S502; Described product also concentrates the memory partitioning of various product and working memory according to one-to-one principle corresponding stored by the product collection described in receiving step S501.
Described working memory is divided into different memory partitionings to store described product collection, such as: the mechanism's product in the middle of product collection, P2P product, bank product and other products, according to the principle of the corresponding series products in memory partitioning, and to be stored in the middle of each self-corresponding memory partitioning.
Coupling subelement 303-2, for reading described trading order form in the middle of the first message-oriented middleware 302, read the product data of described product from the working memory described in step S502, mates the two, and output matching result.
With reference to Fig. 6, show the process flow diagram of the coupling subelement 303-2 processing procedure of a kind of deals match system that the present embodiment provides.
S601; From the working memory described in step S502, find the product that current matching needs most, read the product data of this product and export.
Described product collection is loaded in the middle of working memory from product database by above-mentioned steps S502, and this step searches the product that current matching needs most further in the middle of described working memory, and reads this product data.
From working memory, search described product according to the product data of product described in this step, the concrete B+ of employing sets and sets up index to product, with the product that fast finding is relevant; Certainly, the indexing means using other is not got rid of yet.
B+ tree is a kind of data tree structure, is generally used in the file system of database and operating system.The feature of B+ tree to keep data stabilization orderly, and it inserts and has more stable logarithmic time complexity with amendment.B+ sets element bottom-up insertion, and this and binary tree are just the opposite.
Node in B+ tree is represented as one group of orderly element and sub-pointer usually.If the ordinal number (order) that this B+ sets is m, then each node except root comprises the maximum m-1 of a minimum m/2 element element, has maximum m sub-pointer for arbitrary node.For all non-leaf nodes, the number of sub-pointer always more than the number of element one.
The element of each non-leaf nodes serves as the separation value of separately its subtree.Such as, if non-leaf nodes has three child nodes (or subtree), then it must have two separation values (a1, a2); Values all in the subtree on the left side is all less than a1, and values all in middle subtree is all between a1 and a2, and values all in the subtree on the right is all greater than a2.
The mode of searching of B+ is similar to binary tree search, originates in root node, top-down traverse tree.When searching, if the key value in non-leaf nodes equals the desired value that will inquire about, do not stop inquiry, but continue downwards until leafy node.Therefore, in B+ tree, no matter search success or not, search is all walked a path from root node to leafy node at every turn.
B+ is adopted to set the operational data test comparison of searching the mode of searching of mode and common traversal as follows:
| Product quantity unit/ | Common traversal searches unit/millisecond | B+ tree searches unit/millisecond |
| 10000 | 4981.54 | 1894.237 |
| 20000 | 1677.428 | 139.346 |
| 30000 | 2196.821 | 164.908 |
| 40000 | 3881.273 | 141.766 |
| 50000 | 3907.733 | 129.441 |
| 60000 | 4866.081 | 135.001 |
| 70000 | 5356.214 | 145.497 |
| 80000 | 6052.107 | 128.189 |
| 90000 | 7694.815 | 135.467 |
| 100000 | 7411.704 | 126.357 |
The algorithm complex that common traversal is searched is O [], the complexity of B+ tree algorithm is O [], as can be seen from upper table also, query time based on the mode of searching of common traversal is linear increase substantially, and the query time that B+ tree searches mode is progressively stabilized in a minimum value, there is not the situation of linear increase.In addition, in actual applications, can according to expected yield, product issuing time, product type, production life cycle, the data such as the minimum purchase share of product are set up B+ and are set index, easy-to-look-up.
S602; The product data of the described product that receiving step S601 exports, and described trading order form is read in the middle of the first message-oriented middleware 302, the two is mated.
Read the trading order form in the middle of queue first in described first message-oriented middleware 302, and its product data with described step S601 output products are mated therebetween, and described coupling meets time priority principle and price priority principle.
S603; Judge that whether described coupling is successful.
If the match is successful described in step S602, then perform step S604;
If it fails to match described in step S602, then perform step S605.
S604; Described trading order form is converted to result order and exports.
Described trading order form is converted into result order, and exports described result order to second message-oriented middleware 304; This time transaction processing process completes, and can return step S601 and carry out next round coupling.
S605; Judge whether the matching times of described trading order form exceedes maximum permissible value.
This step carries out the maximum permissible value of matching times according to trading order form in the described transaction queue arranged in advance, judges whether the matching times of current trading order form exceedes this maximum permissible value; If the matching times of described trading order form exceedes this maximum permissible value, then perform step S606; If the matching times of described trading order form does not exceed this maximum permissible value, then perform step S607;
The object arranging the maximum permissible value of matching times is in order to avoid the wasting of resources.In deals match process, sometimes have the trading order form that some conditions are harsh especially, these trading order forms cannot obtain the product on sale matched all the time; And according to the prioritization schemes of this match trading system, this trading order form can obtain very high priority level, like this, will cause match trading system is constantly these trading order form input coefficient resources, but cannot produce and obtain coupling achievement, for this reason, this deals match system pre-sets the maximum permissible value of coupling, as the criterion whether continuing as a certain trading order form input coefficient resource.If exceed this maximum permissible value, then reject this trading order form to save system resource.
S606; Described trading order form is rejected in the middle of described transaction queue.
Rejected in the middle of described transaction queue by described trading order form by matching treatment cluster, this transaction order is judged as that it fails to match, no longer carries out the matching treatment of repetition; As more perfect processing scheme, when being rejected in the middle of described transaction queue by this trading order form, corresponding notification can also be generated, and send it to the client sending relationship trading reservation, due to the Core Feature that this is not this deals match system, no longer describe in detail at this.After completing this step, return step S601, carry out next round coupling.
S607; Described trading order form is proceeded in the middle of the more higher leveled transaction queue of priority from current transaction queue.
Read from the queue first of described first message-oriented middleware 302 by matching treatment cluster by the trading order form of matching treatment if current, then this trading order form is proceeded in the middle of retry queue 1;
Read from the retry queue of described first message-oriented middleware 302 by matching treatment cluster by the trading order form of matching treatment if current, then this trading order form is proceeded to than in the middle of the more higher leveled retry queue of current retry queue priority.
When matching treatment cluster mates with the product in the middle of described product collection described trading order form, described in processing successively according to the priority orders of queue, queue first and retry are to the trading order form in the middle of queue.
The priority of described queue is first lower than the priority of described retry queue; Described retry queue is a set of queues, is made up of multiple retry queue, and the priority of described retry queue is determined according to the number of retries of trading order form in the middle of described retry queue, and the retry queue priority that described number of retries is larger is also higher.Described queue first and the retry global precedence effect level order to team is as follows:
Retry queue n> ... > retry queue 2> retry queue 1> queue first.
In the present embodiment, in described transaction queue group, the processing priority of transaction queue is arranged, and has well distinguished the processing priority of business processing in distributed transaction matching system.
It should be noted that, the quantity of described retry queue is determined according to the overstocked number of trading order form in the middle of retry queue.In described retry queue, the overstocked number of trading order form is relevant with described market model, that is: can configure the quantity of described retry queue according to described market model.
Such as:
Under the model of buyer's market, the seller has enough products to mate, and the probability of retry is extremely low, now, the quantity of retry queue can be configured to 2;
Under the model of seller's market, the supply of product is far smaller than the trading order form of the buyer, and a large amount of trading order forms may cannot find adaptive product in first fit, distinguishes so need to carry out strategy effectively to the application of retry after first purchase and failure.Now, a kind of configuration of recommendation is 10 by retry cohort design.
Although have employed the mode being divided into multiple retry queue according to number of retries in the present embodiment, virtually completely also can adopt and only have a retry queue, retry does not still have the trading order form that the match is successful can reenter described retry queue for the first time, until after number of retries exceedes maximum permissible value, this trading order form is rejected.
