With the explosive development of Internet business, this data update mode can easily lead to data hot spots
When a hot event occurs, such as the issuance of popular commemorative coins, the online reservation rush purchase method is adopted. Each reservation process needs to visit the remaining commemorative coin inventory. After the reservation is successful, the commemorative coin inventory needs to be updated. Since the appointment time is relatively concentrated, it will High concurrent data requests occur, and the judgment and update of commemorative coin inventory are faced with lock waiting. The commemorative coin inventory is "hot data". The access to and update of hot data will seriously affect the performance of the data processing system of the entire system

Embodiment
[0178] Example: find the appropriate payment data x on the right side of the payment data y:
[0179] Table 2
[0180]
[0181]
[0182] The step S010 is used for judging that in A k-i Whether the interval can match record x. which is:
[0183] find_2(y) / / Known A k-1 =[a k-1 ,a k ), y∈(a k-1 ,a k ]
[0184] {
[0185] If(t k-1 ==0 or y==a k ) return(Not_Find); / / The record x is not found, enter the step 3404.
[0186] When y∈(a k-1 ,a k ), look at the A k-1 Does any of the records in meet the requirements, namely:
[0187] Select*fromA k-1 where flags = "unused" and x ≥ y fetch first 1row only;
[0188] If found, then:
[0189] Lock the record; / / If the lock is not successful, it may be locked by others in parallel, then re-query and mark it as "active", that is, complete the positioning, exit the for process of positioning, and return the record x, that is, return(x ), enter the step S012;
[0190] Otherwise: return (Not_Find), enter the step S011. ...

A system and method for processing high-frequency hotspot data, specifically comprising: a data initiation module for receiving an account processing request sent by a user; a high-frequency judgment module for comparing the account processing request with a predetermined threshold, and confirming the account according to the comparison result Whether the processing request is a high-frequency request; the system scheduling module is used to hand over the accounting processing request to the high-frequency data processing module when the accounting processing request is a high-frequency request; and, when the accounting processing request is not a high-frequency request , handing over the accounting processing request to the original data processing system; the high-frequency data processing module is used to obtain multiple sub-tables of different intervals through data distribution processing, wherein the sub-table contains multiple records; and judge the received accounting Processing request type, processing sub-tables or records according to the type of accounting processing request; the native data processing system is used to perform preset processing on the received accounting processing request.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a high-frequency hotspot data processing system and method for high-frequency access and update of hotspot data. Background technique [0002] At present, data update in many data processing systems needs to be judged according to a "baseline value" (such as an account balance). With the explosive development of Internet services, this data update mode is likely to cause data hotspots. When a hot event occurs, such as the issuance of popular commemorative coins, the online reservation rush purchase method is adopted. Each reservation process needs to visit the remaining commemorative coin inventory. After the reservation is successful, the commemorative coin inventory needs to be updated. Since the appointment time is relatively concentrated, it will Highly concurrent data requests occur, and the judgment and update of commemorative coin inventory are faced with ...
