When online transaction is carried out, share data of the deposit product has uniqueness, each share processing request needs exclusive access and updating to the share data, when the quantity of concurrent transaction requests is large, a large amount of lock competition and lock waiting are generated when a database is updated, the processing speed is greatly reduced, the transaction is blocked, and the throughput of the system is reduced.
In view of the above problems, a patent "quota resource processing method, online transaction processing method and apparatus" (application number: CN 104599177A) disclosed in the prior art writes a quota processing request into a database quota application table, when unprocessed data in the quota application table is greater than a certain number or an earliest unprocessed data is greater than a certain time interval from the current time, the data in the quota application table is summarized and calculated to obtain a total quota, then the total quota and the remaining quota of the database are determined, if the total quota is smaller, the status of all quota applications in the database quota and quota application table is updated to be successful, and if the total quota is larger, the size of the application quota and the remaining quota of the database are sequentially compared according to a quota application order, and the status of the remaining quota and quota application table of the database is updated.
The technical scheme has the following defects: the share processing result cannot be obtained in real time, and the client cannot know the transaction result in online transaction; the share processing only carries out deduction and does not carry out adding back; each share processing request needs to write in the database, and when the request concurrency is high, the request concurrency is easy to generate larger pressure on the database, and the normal operation of other services is influenced.
Disclosure of Invention
The invention provides a method for improving the real-time online transaction share processing speed of online deposit products, aiming at the problems that in the prior art, the share processing result cannot be obtained in real time, each share processing request needs to be written into a database, when the request concurrency is high, the database is easy to generate larger pressure, and the normal operation of other services is influenced, and the method aims to solve the problems that: the result of the share processing request can be obtained in real time; the read-write frequency of the database is reduced, the share processing speed of the deposit products is improved, and the response speed of online transaction requests is accelerated.
The technical scheme adopted by the invention is as follows:
a method of increasing the speed of processing shares of a real-time online transaction of an online credit product, comprising:
step S1: initializing share parameters of the deposit product, and storing the share parameters into a database, wherein the share parameters comprise a total share, a used share, a pre-read share, a share deduction threshold and a share adding threshold;
step S2: starting a cache server, and initializing a product share cache item on the cache server according to the product share related parameters in the database;
step S3: when a deposit product is deposited or withdrawn, storing a deposited deposit product code, a deposited amount or a withdrawn deposit product code and a withdrawn amount to a cache server, reading a product share current value corresponding to the deposit product code in real time by the cache server for judgment, and deducting or adding back the product share current value and responding to a result if conditions are met;
step S4: and the timing task reads the product share in the cache server at regular time, and deducts or adds the current value of the product share in the cache server to the database.
Further, in step S1, the share deduction threshold is smaller than the share deduction threshold, and a value obtained by subtracting the share deduction threshold from the share deduction threshold is larger than the value of the pre-read share.
Further, step S2 is specifically:
step S2.1: reading share parameters of the deposit products in the database, and comparing the sum of the used shares and the pre-read shares with the size of the total shares;
step S2.2: if the sum of the used share and the pre-read share is larger than the total share, storing a value obtained by subtracting the used share from the total share to the product share of the cache server, and updating the value of the total share to the used share in the database;
step S2.3: and if the value of the used share plus the pre-read share is less than or equal to the value of the total share, updating the value of the pre-read share to the product share of the cache server, and updating the value of the used share plus the value of the pre-read share to the used share in the database.
When the cache server is started, the pre-read share is read from the database and stored in the cache server, and as the condition that the cache server is restarted occurs, the original cache is lost when the cache server is restarted, and the cache needs to be initialized again, when the cache server is started, the sum of the used share and the pre-read share in the database and the total share need to be judged firstly to select a mode of extracting the credit share, so that no matter whether the cache server is started for the first time or restarted, the quota needs to be extracted through the judgment process.
Further, in step S3:
when a deposit product is deposited, storing the deposited deposit product code and the deposited amount to a cache server;
the cache server reads the product share corresponding to the deposit product code;
if the product share does not exist, the response result of the cache server is that the product share does not exist;
if the product share exists, comparing the current value of the product share with the value of the deposit amount;
if the current value of the product share is smaller than the deposit amount, the response result of the cache server is that the product share is insufficient;
and if the current value of the product share is larger than or equal to the deposit amount, updating a value obtained by subtracting the deposit amount from the current value of the product share to the product share, and successfully deducting the product share according to a response result of the cache server.
In step S3:
when a deposit product is paid out, the server caches the code of the paid out deposit product and the saved value of the paid out amount;
the cache server reads the product share corresponding to the deposit product code;
if the product share does not exist, the response result of the cache server is that the product share does not exist;
if the product share exists, the value obtained by adding the current value of the product share to the payment amount is updated to the product share, and the response result of the cache server is that the product share is successfully added.
Further, in step S3, the cache server serially executes the share processing request for the deposit product. The value of the product share in the cache server performs addition and subtraction on the product share by executing the product share processing request, so that the product share is updated.
Further, step S4 is specifically:
step S4.1: reading the current value of the product share in the cache server at regular time, and comparing the current value of the product share with the size of a share adding threshold and a share deducting threshold;
step S4.2: if the current value of the product share is less than or equal to the share deduction threshold value, comparing whether the sum of the used share and the pre-read share in the database is greater than the total share, if so, subtracting the sum of the used share plus the current value of the product share from the total share and updating the sum to the product share in the cache server, and if not, updating the sum of the pre-read share and the current value of the product share to the used share in the database;
step S4.3: if the current value of the product share is larger than or equal to the share back-adding threshold, updating a value obtained by subtracting the pre-read share from the current value of the product share to the product share in the cache server, and updating a value obtained by subtracting the pre-read share from the value of the used share to the used share in the database;
step S4.4: if the current value of the product share is greater than the share deduction threshold and less than the share add-back threshold, no action is performed.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that: the share processing request result can be obtained in real time, the deposit product online transaction share processing request does not directly read and write the database but read and write the cache, the reading and writing frequency of the database is reduced, the share processing speed of the deposit product is improved, and the response speed of the online transaction request is accelerated.

if the product share exists, the value obtained by adding the current value of the product share to the payment amount is updated to the product share, and the response result of the cache server is that the product share is successfully added.
In step S3, the cache server serially executes the share processing request of the deposit product.
Step S4: and the timing task reads the product share in the cache server at regular time, and deducts or adds the current value of the product share in the cache server to the database. Step S4 specifically includes:
step S4.1: reading the current value of the product share in the cache server at regular time, and comparing the current value of the product share with the size of a share adding threshold and a share deducting threshold;
step S4.2: if the current value of the product share is less than or equal to the share deduction threshold value, comparing whether the sum of the used share and the pre-read share in the database is greater than the total share, if so, subtracting the sum of the used share plus the current value of the product share from the total share and updating the sum to the product share in the cache server, and if not, updating the sum of the pre-read share and the current value of the product share to the used share in the database;
step S4.3: if the current value of the product share is larger than or equal to the share back-adding threshold, updating a value obtained by subtracting the pre-read share from the current value of the product share to the product share in the cache server, and updating a value obtained by subtracting the pre-read share from the value of the used share to the used share in the database;
step S4.4: if the current value of the product share is greater than the share deduction threshold and less than the share add-back threshold, no action is performed.
Example (b):
step S1: defining the total share 100 of the deposit product, the used share 0, the pre-reading share 10, the share deduction threshold value 8 and the share adding back threshold value 23 to be stored in a database;
step S2: when the cache server is started, the cache server reads relevant parameters of product shares in the database, and compares the value of the used share plus the pre-read share with the total share;
the value 10 of the used share 0 plus the pre-read share is less than the value 100 of the total share, the value 10 of the pre-read share is updated to the product share of the cache server, and the value 10 of the used share 0 plus the pre-read share 10 is updated to the used share.
Step S3:
when a deposit product is deposited, a deposited deposit product code and a deposited amount saving value are cached in a server;
the cache server reads the product share corresponding to the deposit product code in the memory;
if the product share does not exist, the response result of the cache server is that the product share does not exist;
if the product share exists, comparing the product share with the amount of the deposit;
when the product share is 20 and the deposit amount is 25, the response result of the cache server is that the product share is insufficient;
when the product share is 20 and the credit is 15, the value 5 obtained by subtracting the credit 15 from the value 20 of the product share is updated to the product share, and the corresponding result of the cache server is that the product share is successfully subtracted.
When a deposit product is paid out, the server caches the code of the paid out deposit product and the saved value of the paid out amount;
the cache server reads the product share corresponding to the deposit product code in the memory;
if the product share does not exist, the response result of the cache server is that the product share does not exist;
when the product share exists, the product share is 10, and the draw amount is 10, the value 20 obtained by adding the draw amount 10 to the product share 10 is updated to the product share, and the cache server responds that the product share is successfully added back.
The cache server serially executes the share processing request of the deposit product.
Step S4:
reading the product share in the cache server at regular time, and comparing the product share with two thresholds, wherein the two thresholds are a share adding threshold and a share deducting threshold;
if the value of the product share is read to be 5 and is smaller than the share deduction threshold value 8, comparing whether the value of the used share plus the pre-read share in the database is larger than the total share, if the value of the used share is 93 and the value of the used share 93 plus the pre-read share is 10 and is larger than the total share 100, updating the value of the total share 100 minus the value of the used share 93 plus the value of the product share 5 into the product share data of the cache server, the updated product share has a value of 12, if the used share is 50 at this time, the value of the used share 50 plus the pre-read share 10 is less than the total share 100, the value of the pre-read share 10 plus the value of the product share 5 is updated into the product share data of the cache server, the value of the updated product share is 15, and the value 60 of the used share, which is obtained by adding 50 to the pre-read share 10, is updated into the data of the used share;
if the value of the product share is 30, the value of the used share is 50, and the product share 30 is greater than the share back addition threshold value 23, updating the value 20 obtained by subtracting the pre-read share 10 from the product share 30 into the product share data of the cache server, and updating the value 40 obtained by subtracting the pre-read share 10 from the value 50 of the used share into the used share data of the database, wherein the value of the used share after updating is 40;
if the value of the product share is greater than the share deduction threshold and less than the share add-back threshold, then nothing is done.
According to the invention, under the scene of online product storage and withdrawal, partial product share data is read to the cache server for storage, and the share on the cache server is used up and then a fixed share is obtained from the database to the server until the total share is used up.
The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which are all within the protection scope of the present application.
