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

[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. ...

The invention discloses a high-frequency hotspot data processing system and method. The system specifically comprises: a data initiating module used for receiving an account processing request sent by a user; a high-frequency judgment module used for comparing the account processing request with a preset threshold value and confirming whether the account processing request is a high-frequency request or not according to a comparison result; a system scheduling module used for transferring the account processing request to a high-frequency data processing module when the account processing request is a high-frequency request, and transferring the account processing request to an original data processing system when the account processing request is not the high-frequency request; the high-frequency data processing module used for obtaining a plurality of sub-tables of different interval sections through data distribution processing, wherein the sub-tables comprise a plurality of records, judging the type of the received account processing request, and processing the sub-table or the record according to the type of the account processing request; and the original data processing system used for performing preset processing on the received account 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 ...
