Step 210, the first application server determines data to be written.
The first application server herein can be for appointing for disposing in the application server cluster of same operation system
One application server.Such as, can be any application server for disposing in the application server cluster of Taobao's transaction system,
Can also be for disposing any application server in Alipay account systematic difference server cluster.
In step 210, the first application server can determine data to be written by two ways：First way
It is that the first application server is wanted to improve the access efficiency of a certain data, then the data can be defined as into data to be written.The
Two kinds of modes are that the first application server receives the write data requests of called side, and the write data requests include the number of request write-in
According to, then can by the request write data be defined as data to be written.
Alternatively, it is determined that after data to be written, the mark of the data to be written can also be determined.In an example
In, the first application server can determine above-mentioned mark according to the most frequently used use condition of business.Such as, in application server collection
Group 10 on dispose operation system be Taobao's transaction system when, it is determined that data to be written mark can be commodity ID,
And on application server cluster 10 dispose operation system be Alipay account system when, it is determined that data to be written mark
It can be the ID of user to know.
Step 220, is written into data Cun Chudao local caches.
Local cache herein can refer to the internal memory of the first application server.
Alternatively, the data in local cache can be stored in queue.Data in local cache are storages
When in queue, the first application server can first judge the length of queue before data Cun Chudao local caches are written into
Whether degree exceedes predetermined threshold value, if not less than predetermined threshold value, being directly written into the afterbody of queue described in data Cun Chudao；And
If exceeding predetermined threshold value, algorithm can be removed according to default data, the data in queue are removed, such as, according to
Data in queue are removed by first in first out (First In FirstOut, FIFO) algorithm, and data are written into afterwards
Store remove data after queue in.
Certainly, in actual applications, the first application server can also by another way safeguard the queue of internal memory,
The application is not construed as limiting to this.Such as, the first application server can periodically judge data in queue whether over-time threshold
Value, if over-time threshold value, the data is removed.
It should be noted that in the case where the mark of data to be written is also determined, the first application server can also be by
The mark is also stored into the queue of local cache.In one example, the mark of data and to be written can be written into
Data in the form of the key-value pair storage in the queue of local cache.Such as,<KEY, DATA>, wherein, KEY refers to data to be written
Mark, DATA refers to data to be written.
Step 230, sends the first far call and asks to remote storage server.
