Paged data content is directly read in caching system, to guarantee access speed.Server end to the information list content into
When row updates, caching system reads updated information list data, carries out paging according to current paging type.Simultaneously to version
The value of number parameter does upgrading processing, and is associated with the slow of the version number after paging label, upgrading and updated paged data content
Deposit mapping.When being switched to a certain page access, version number's parameter after marking and be incremented by according to paging positions to be read user in this way
Newest paged data content is got, and paging caching before then fails.Above technical scheme can in caching system structure
It builds paging caching and guarantees that user's using terminal obtains the reading speed of information list, while when information list content updates,
Old paged data content can all fail, and avoid and need to judge what update was influenced when each information list content updates
A series of cumbersome work such as paged data content.
Embodiment two: as shown in Fig. 2, the present embodiment provides a kind of buffer service methods, comprising:
201 when receiving the read requests for being directed to information list of terminal transmission, from the database reading information list
Data content, and generate paging caching according to the selected paging type of user.
The paging of 202 default each paging pages of corresponding informance list caches name, presets each paging page of corresponding informance list
Version number's parameter, version number's parameter of each paging of corresponding informance list is mutually indepedent.
203 pagings cache naming mechanism and increase version number's parameter as suffix.
In existing caching system, it is to be marked using paging caching name as paging, corresponds to same point in paging caching
The paging caching name and paged data content of the page page are with the relationship of " key-value ".System caches name by paging and looks into
It finds paged data content and is read out equal sequence of operations.
The slow naming mechanism of paging increases version number's parameter as suffix, can establish the paging of the corresponding same paging page
The Cache associativity relationship of slow name, version number's parameter and paged data content.
By taking a news information list as an example, the paging caching naming mechanism for increasing version number's parameter as suffix be can be
Form as wzxc_newslist_pN_vM (prefix _ news list _ paging code _ version number), wherein the value of N be 1,2 ... N；
The value of M be 1,2 ... M, using the paging caching naming mechanism paging caching name be then wzxc_newslist_p1_v1,
Wzxc_newslist_p2_v2 etc..
204, when the data content of the information list in server updates, read the number of updated information list
According to content, incremental processing is done to version number's parameter corresponding to all pagings.
The incremental processing refers to that the numerical value to version number's parameter does+1 and is incremented by processing, and paging caches entitled wzxc_
The paging of newslist_p1_v1 caches, after primary update occurs for information list data content, the numerical value of version number's parameter does+
After 1 is incremented by processing, new paging caches entitled wzxc_newslist_p1_v2, caching name and updated this page of paging
Data content association caching mapping is read in this way with the caching name of wzxc_newslist_p1_v2 data cached for more
Paged data content after new.Similarly it is incremented by processing and is also possible to+2 or+3 or other incremental processing modes, this is this technology neck
Details are not described herein for the customary means in domain.
205 when receiving the read requests for a certain paging page of information list, is had according to the generation of the corresponding paging
The paging that last time is incremented by treated version number's parameter suffix caches name, finds the updated paged data of last time
Content, the paged data content described to terminal push.
In each data cached update, version number's parameter carries out being incremented by processing, so that paging caching name changes, and
So that former paging caching is become invalid cache, this ensures that read every time it is data cached be all newest.This method is not necessarily to
Data cached which paging specifically influenced judged, therefore is easier to realize.And it is cached again compared to all pagings are directly deleted
The method for generating paging caching, this method cache maintenance are more convenient not easy to make mistakes.After former paging caching becomes invalid cache, meeting
According to being automatically deleted after the expired time of caching system.
As shown in figure 4, the process for pushing paged data content in the present embodiment includes:
Maintenance list is preset in 401 caching systems, for storing the single Information ID in information list.
402 when receiving the reading order for a certain paged content of information list, and first inquiry maintenance list caching is
No presence reads if maintenance column table cache is not present and generates maintenance column table cache.
If 403 maintenance column table caches it is existing or generate maintenance column table cache after, filter out the single letter for belonging to the paging
Cease ID.
The caching of the corresponding single information of the single Information ID of each of the paging described in 404 cyclic queries whether there is, if
The caching of the single corresponding single information of Information ID is not present, and reads the corresponding single information content of the single Information ID, generates
The caching of the corresponding single information of the Information ID, and it is data cached to push this；If the corresponding single information of single Information ID is slow
Exist, then pushes the data cached of the corresponding single information of the single Information ID.
This method, the buffer service side provided as the present embodiment are used in the paging caching for reading information list
Method advanced optimizes.The paged data content segmentation of information list is the caching number of single information with smaller capacity by this method
According to, so that the single information is affected only for the update of single information from the background, cache storage can be greatly reduced in this way
The capacity of content, significantly improves reading speed.When to reduce each buffer update, individual data terminal and cache server
Between volume of transmitted data, therefore delay caused by concurrent amount of access increases can be significantly reduced.
Embodiment three: as shown in figure 3, the present embodiment provides a kind of buffer service methods, comprising:
301 when receiving the read requests for being directed to information list of terminal transmission, from the database reading information list
Data content, and generate paging caching according to the selected paging type of user.
The paging of 302 default each pagings of corresponding informance list caches name, presets the version number of each paging of corresponding informance list
Version number's parameter of parameter, each paging of corresponding informance list is mutually indepedent.
By taking a news information list as an example, paging caching naming mechanism is wzxc_newslist_pN (prefix _ news column
Table _ paging code), form as N that the value of N is 1,2 ....
The form of 303 paged data contents is set as by the two-dimensional array of version number's parameter and paged data Composition of contents:
The form of array (version number's parameter, paged data content).
By taking a news information list as an example, the paged data content stored in the form of described be can be, in corresponding first page
The paged data content that the paging of appearance caches entitled wzxc_newslist_pN (prefix _ news list _ paging code) is array
(M, paged data content), wherein the value of N be 1,2 ... N；The value of M is 1,2 ... M.
304 default version number's records, for storing current version number value；It is described to version number corresponding to all pagings
Parameter, which is done, to be incremented by processing and refers to, does incremental processing to the version number value in version number's record, and the version number that will be incremented by that treated
Value is assigned to version number's parameter corresponding to all pagings.
The incremental processing refers to that the numerical value to version number's parameter does+1 and is incremented by processing.It is with a news information list
Example, when reading information list for the first time, the version number value stored in version number's record is 1, the paging caching of corresponding first page content
Entitled wzxc_newslist_p1, corresponding paging caching is array (1, paged data content), in the news information list number
After primary update occurs according to content, after the numerical value of version number's parameter does+1 incremental processing, the version number of storage in version number's record
Value is 2, paging cache the corresponding paging caching of entitled wzxc_newslist_p1 be array (2, new paged data content) or
Array (1, old paged data content) is similarly incremented by processing and is also possible to+2 or+3 or other incremental processing modes, this is this
Details are not described herein for the customary means of technical field.
305 when receiving the reading order for a certain paged content of information list, and paging caching name is corresponding
Version number value in array (version number's parameter, paged data content) in version number's parameter and version number's record is compared, and is read
Point in the array (version number's parameter, paged data content) for the version number value for taking version number's parameter to be equal in version number's record
Page data content, and delete array (version number parameter, paging of version number's parameter less than the version number value in version number's record
Data content).
After news information list updates, when user reads again the content of first page, according in corresponding first page
The paging of appearance caches entitled wzxc_newslist_p1, and inquiring corresponding paging caching is array (2, paged data content)
Or array (1, paged data content), the version number value stored in version number's record at this time is 2, and reading array (2, paging number
According to content) in paged data content, and delete array (1, paged data content).
Not only can guarantee in this way read every time it is data cached all to be newest, but also compared to the method implemented in one, energy
It is enough to delete former paging caching, avoid the former paging caching as Trash cache from occupying excessive space.This method is slow without judgement
Which paging that deposit data specifically influences, therefore be easier to realize.And it is regenerated point compared to all pagings caching is directly deleted
The method of caching of page, this method cache maintenance is more convenient, not easy to make mistakes.
As shown in figure 4, the process for pushing paged data content in the present embodiment includes:
Maintenance list is preset in 401 caching systems, for storing the single Information ID in information list.
402 when receiving the reading order for a certain paged content of information list, and first inquiry maintenance list caching is
No presence reads if maintenance column table cache is not present and generates maintenance column table cache.
If 403 maintenance column table caches it is existing or generate maintenance column table cache after, filter out the single letter for belonging to the paging
Cease ID.
The caching of the corresponding single information of the single Information ID of each of the paging described in 404 cyclic queries whether there is, if
The caching of the single corresponding single information of Information ID is not present, and reads the corresponding single information content of the single Information ID, generates
The caching of the corresponding single information of the Information ID, and it is data cached to push this；If the corresponding single information of single Information ID is slow
Exist, then pushes the data cached of the corresponding single information of the single Information ID.
This method, the buffer service side provided as the present embodiment are used in the paging caching for reading information list
Method advanced optimizes.The paged data content segmentation of information list is the caching number of single information with smaller capacity by this method
According to, so that the single information is affected only for the update of single information from the background, cache storage can be greatly reduced in this way
The capacity of content, significantly improves reading speed.When to reduce each buffer update, individual data terminal and cache server
Between volume of transmitted data, therefore delay caused by concurrent amount of access increases can be significantly reduced.
