Fig. 5 is the logical schematic according to the quantitative storage 500 of embodiment of the present invention.The operation that wherein Meituan is taken out is general The operation probability that rate is 10% and Baidu takes out is 9%, therefore the storage rank that Meituan is taken out and Baidu takes out is quantitative storage Grade.According to the memory capacity 20M for taking out the dynamic storage cell of quantitative storage level distributed by Meituan, from appearance outside Meituan Associated (all) multiple data files select at least one data file (to deposit needed at least one selected data file Store up capacity and be less than 20M), and at least one selected data file is copied to from second memory as dynamic storage cell 501.According to the memory capacity 10M for the dynamic storage cell for taking out the quantitative storage level distributed by Baidu, taken out from Meituan Associated (all) multiple data files select at least one data file (needed at least one selected data file Memory capacity is less than 10M), and at least one selected data file is copied to from second memory as dynamic memory list Member 511.

Alternatively, wherein prefetching user using the dynamic of the quantitative storage level distributed according to for each of quantitative storage level The memory capacity of state storage unit is selected from user is prefetched with each of quantitative storage level using associated multiple data files At least one data file includes:

It is deposited according to quantifying of each prefetching that user's application (Meituan is taken out or Baidu's take-away) distributed for quantitative storage level Store up grade dynamic storage cell (501 or 511) memory capacity by with quantitative storage level each prefetch user apply it is associated Multiple data files be grouped to generate multiple file groups, wherein each file group includes at least one data file.Its In each file group at least one data file needed for total memory capacity be less than the dynamic of corresponding quantitatively storage level and deposit The memory capacity of storage unit.That is, total memory capacity of all data files is less than 20M in each file group that Meituan is taken out, And total memory capacity of all data files is less than 10M in each grouping that Baidu takes out.For each of quantitative storage level Different priority is arranged to constitute priority query in the multiple file groups for prefetching user's application.For example, it includes 5 that Meituan, which is taken out, File group, and the priority of 5 file groups is 1,2,3,4 and 5 (wherein digital smaller priority is higher).By each priority In queue positioned at the file group (priority be 1 file group) of head of the queue as current file group and by current file group at least One data file copies to from second memory and prefetches the quantitative storage that user's application distributes by each of quantitative storage level The dynamic storage cell (for example, dynamic storage cell 501) of grade.It is each dynamic memory for quantifying storage level after the completion of duplication Third time cycle (for example, 30 seconds, 60 seconds or 90 seconds) are arranged in unit (501 or 511).When expiring the third time cycle (that is, whenever have passed through 30 seconds, 60 seconds, 60 seconds), the next file in sequence use priority queue reduced according to priority Group (such as priority is 2 file group) is used as current file group, until next file group is not present.That is, by priority 1, until 2,3,4 and 5 file group copies to after dynamic storage cell 501 or 511.It follows that when time long enough (foot Enough be greater than multiple phases third time cycle) when, for example, the third time cycle is 90 seconds, and reach the 450th second (i.e. 5 the When three time cycles), the All Files group in 5 file groups was both used as current file group.In this case, not to dynamic Content in state storage unit (501 or 511) is updated, i.e., reservation priority is literary at least one data of 5 file group Part is in dynamic storage cell 501.

At least one data file in current file group (may be the file group that priority is 1,2,3,4 or 5) is made To prefetch at least one data file that user selects using associated multiple data files from each of quantitative storage level. Wherein the size size of all data files (that is, in file group) of each file group is less than the dynamic of corresponding quantitatively storage level The memory space of storage unit.Alternatively, wherein determining according to user is prefetched for each of quantitative storage level using what is distributed Measure storage level dynamic storage cell memory capacity, from quantitative storage level each prefetch user apply it is associated multiple Data file selects at least one data file to include:

It is deposited according to quantifying of each prefetching that user's application (Meituan is taken out or Baidu's take-away) distributed for quantitative storage level Store up grade dynamic storage cell (501 or 511) memory capacity by with quantitative storage level each prefetch user apply it is associated Multiple data files be grouped to generate multiple file groups, wherein each file group include at least one data file wherein Total memory capacity needed at least one data file of each file group is less than the dynamic memory of corresponding quantitatively storage level The memory capacity of unit.That is, total memory capacity of all data files is less than 20M in each file group that Meituan is taken out, and And total memory capacity of all data files is less than 10M in each grouping of Baidu's take-away.For example, it includes 5 that Meituan, which is taken out, File group, and the serial number 1,2,3,4 and 5 of 5 file groups.A file group is randomly choosed from the multiple file group (the file group of serial number 5) is as current file group and by least one data file in current file group from second memory It copies to and the dynamic storage cell for the quantitative storage level that user's application distributes is prefetched (for example, dynamic by each of quantitative storage level State storage unit 501) and be each dynamic storage cell (501 or 511) the setting third for quantifying storage level after the completion of duplication Time cycle (for example, 30 seconds, 60 seconds or 90 seconds).Whenever the third time cycle expire when (that is, whenever have passed through 30 seconds, 60 seconds, 60 seconds), next file group (for example, file group of serial number 2) is randomly choosed from multiple file groups as current file group, directly To there is no until next file group.The file group of serial number 1,2,3,4 and 5 is copied into dynamic storage cell 501 or 511 Until afterwards.It follows that when time long enough (being sufficiently more than multiple phases third time cycle), for example, the third time cycle It is 90 seconds, and reaches the 450th second (i.e. when 5 third time cycles), the All Files group in 5 file groups was both used as Current file group.In this case, be not updated to the content in dynamic storage cell (501 or 511), that is, retain with At least one data file of the last one file group (such as file group 1) of machine selection is in dynamic storage cell 501.

Using at least one data file in current file group (may be the file group of serial number 1,2,3,4 or 5) as At least one data file that user selects using associated multiple data files is prefetched from each of quantitative storage level.Its In the size size of all data files (that is, in file group) of each file group be less than the dynamic of corresponding quantitatively storage level and deposit The memory space of storage unit.

Alternatively, at least one selected data file is being copied to from second memory as quantitative storage level Each prefetch the quantitative storage level that user's application (Meituan take out or Baidu take out) is distributed dynamic storage cell (501 or 511) after, third time cycle (for example, 30 seconds, 60 seconds or 90 seconds) is set and start timing, whenever the third time cycle When (for example, 30 seconds, 60 seconds or 90 seconds) expire, user's application (Meituan take-away or hundred are prefetched according to for each of quantitative storage level Be outside one's consideration and sell) memory capacity (20M or 10M) of the dynamic storage cell (501 or 511) of quantitative storage level distributed, again from With each of quantitative storage level prefetch user using associated multiple data files it is random/select at least one data in order At least one data file reselected is copied to from second memory and prefetches user for each of quantitative storage level by file Using the dynamic storage cell (20M or 10M) for the quantitative storage level that (Meituan is taken out or Baidu takes out) is distributed.Wherein, pass through The data file at least one data file that randomly selected mode reselects may be with randomly selected number before It is identical according to file.The data file at least one data file reselected by way of selecting in order will not be therewith The preceding arbitrary data file selected in order is identical.

Alternatively, wherein prefetching user using the dynamic of the quantitative storage level distributed according to for each of quantitative storage level The memory capacity of state storage unit is selected from user is prefetched with each of quantitative storage level using associated multiple data files At least one data file includes the following steps: (1) that (Meituan is taken out or Baidu according to user's application is prefetched for each of quantitative storage level Take out) memory capacity (20M or 10M) of the dynamic storage cell (501 or 511) of quantitative storage level distributed will with quantitatively deposit Each of storage grade prefetches user and is grouped using associated multiple data files to generate a file group of N (for example, N=5), Wherein N is greater than 1 natural number and each file group includes at least one data file；

Different serial numbers is arranged for each file group in N number of file group in step 2, wherein the serial number is from 1 to N (example Such as, 1,2,3,4 and 5)；

Step 4, for quantitative storage level each dynamic storage cell (501 or 511) be arranged the third time cycle (for example, 30 seconds, 60 seconds or 90 seconds)；

Step 5 copies at least one data file included by current file group quantitatively to deposit from second memory Each of storage grade prefetches the dynamic storage cell for the quantitative storage level that user's application is distributed, and starts timing；

Step 6, when the third time cycle expire when, judge whether i=N (that is, whether i=5 true) true, if at It is vertical, then terminate；If invalid, using the file group of serial number i=i+1 as current file group, step 5 is carried out；

Wherein the size of each file group is less than the memory capacity of the dynamic storage cell (501 or 511) of quantitative storage level (20M or 10M).That is, total memory capacity of all data files is less than 20M, and hundred in each file group that Meituan is taken out Total memory capacity of all data files in each grouping sold of being outside one's consideration is less than 10M.For example, it includes 5 files that Meituan, which is taken out, Group, and the serial number 1,2,3,4 and 5 of 5 file groups.

In step 6, if set up, terminate, it is meant that: the file group of serial number 1,2,3,4 and 5 is copied to dynamic Stop duplication after state storage unit 501 or 511.It follows that when time long enough (is sufficiently more than multiple third time cycles Phase) when, for example, the third time cycle is 90 seconds, and reach the 450th second (i.e. when 5 third time cycles), 5 files All Files group in group was both used as current file group.In this case, not to dynamic storage cell (501 or 511) In content be updated, that is, retain the last one randomly selected file group (such as file group 5) at least one data text Part is in dynamic storage cell 501.
