Table 1
In step S220, target data is distributed the first object into the first data Layer according to first property value by Agent layer
Back end, and target data is distributed to the second target data node into the second data Layer according to the second attribute value.
Agent layer usually has the function of routing in distributed data base, and data Layer can not directly be handed over external node
Mutually, task is assigned to each back end by Agent layer.Allocation rule is usually preset distribution logic, in the present embodiment,
Allocation rule may include two parts:Mapping relations are established between the back end in first property value and the first data Layer,
And mapping relations are established between the back end in the second attribute value and the second data Layer, so as to be mapped according to two kinds
Relationship distributes target data twice.Such as the target data in table 1 is distributed into each back end shown in FIG. 1, first
Data Layer 102 can correspond to Location attribute, wherein the target data of " Location value=Shenzhen " is distributed to number
It distributes according to the target data of node 01, " Location value=Shanghai " to back end 03;Second data Layer 103 can be right
Should be in Type attribute, wherein the target data of " Type value=car " is distributed to back end 02, the target of " Type value=life "
Data are distributed to back end 04, and the target data of " Type value=property " is distributed to back end 06.Then allocation result
As shown in table 2, wherein each target data has been assigned in two back end, such as " 14330 " have been assigned to number simultaneously
According in node 01 and back end 02.
Table 2
In step S230, first object back end and the second target data node store assigned number of targets respectively
According to.
After determining first object back end and the second target data node, two nodes are received respectively by Agent layer point
The target data matched, and stored, then target data can be stored respectively in two back end.With the distribution in table 2
It as a result,, can flexible choice data according to the actual situation when external request reads data after completing target data storage for
Node is to transfer target data, such as request reads insuring for Shenzhen and records data, can transfer from back end 01
The target data of " Location value=Shenzhen ", request read insuring for property insurance type and record data, can be from data
The target data etc. of " Type value=property " is transferred in node 06, so that reading number can be met by a back end
According to request, reduce Agent layer and interact caused high workload and long response time with multiple back end.In addition, first belongs to
Property value can be different according to the actual situation from the selection of the second attribute value, are not limited to situation shown in table 2, such as table 1
For, if more in practical application retrieve data according to time or insurer, first property value can also be chosen
Time value, the second attribute value can also choose Applicant value etc..The present embodiment is not specially limited this.
Based on the setting of two data Layers, data disaster tolerance may be implemented.Such as disaster occurs for back end 01, causes wherein
Data when all lossing, Agent layer can traverse all back end of the second data Layer, therefrom read " Location value=
The data of Shenzhen ", in the back end 01 after being copied into calamity, to help back end 01 to rebuild;Work as back end
When data in 06 are loss because of disaster, Agent layer can traverse all back end of the first data Layer, therefrom read
The data of " Type value=property ", to complete to rebuild in the back end 06 after being copied into calamity.
In above-mentioned date storage method, the Agent layer of distributed data base is receiving external request write-in target data
Task after, respectively according to the first property value of target data and the second attribute value assign it to first object back end with
It is stored on second target data node.On the one hand, target data is respectively according to first property value and the second attribute value two
Distributed storage is formed on a data Layer, it, can be according to specific demand flexible choice from when external request reading data
Called data in one data Layer or the second data Layer, so as to reduce back end quantity involved in data read request,
The workload that system processes data reads task is reduced, the response time of the process is shortened.On the other hand, in the present embodiment,
Each target data is stored respectively in two back end, equivalent to increase a data backup, when a data Layer
In back end occur disaster when, can by another data Layer to occur disaster back end rebuild, with realize
The long-distance disaster of back end, to improve the reliability of system.
It in one exemplary embodiment, can also be in distributed data base when target data has multiple attribute values
Third data Layer or even the four, the 5th data Layers etc. are added, to meet the diversified demand of reading data in practical application.
By increase back end, and in Agent layer configure about third attribute value, the 4th attribute value etc. allocation rule and with
The mapping relations of newly-increased back end, it may be convenient to realize the increase of data Layer and the dilatation of system.
In one exemplary embodiment, step S220 can be realized by the step S301 to step S304 in Fig. 3:Step
In S301, Agent layer carries out the first subseries to target data according to first property value, and according to the second attribute value to target
Data carry out the second subseries;In step S302, the first data Layer is according to the first subseries as a result, specified first object data
Node;In step S303, the second data Layer is according to the second subseries as a result, specified second target data node;Step S304
In, Agent layer distributes target data to first object back end and the second target data node.Classification refers in attribute value
The mapping relations of many-one (or one-to-one) are established between back end, can be not exactly the same by attribute value but have general character
Target data is distributed into same back end, to improve the utilization rate of back end.In the present embodiment, responsible pair of Agent layer
First property value is classified with the second attribute value, obtains classification results.And which data section specific classification results correspond to
Point then matches classification results with the property value set of itself by each back end, wherein one in the first data Layer
Back end will match the success of first time classification results, can declare to become first object back end, in the second data Layer
One back end will match second of classification results success, can declare to become the second target data node.Then Agent layer
Distribution can be completed respectively using first object back end and the second target data node as destination.
In one exemplary embodiment, the first subseries and the second subseries may include Hash forwarding.Hash forwards
A kind of implementation of field formula classification is carried out to first property value and the second attribute value, its main feature is that the input space is much larger than defeated
Space out is a kind of many-to-one mapping relations.In the present embodiment, in order to guarantee the first subseries to target data and
Secondary classification result is different, can be by being turned from the second subseries using different hash algorithms in the first subseries
Hair makes two kinds of Hash forwarding values have apparent difference (digit difference, the system difference of such as numerical value), such as the first hash algorithm
All use middle square method with the second hash algorithm, but wherein the first hash algorithm take the 7th be and the 9th bit value, the second Hash
Algorithm takes the bit value of the 6th, the 8th and the 10th, then the output result of two kinds of hash algorithms has apparent difference.
The Hash repeating process of first subseries is illustrated:Agent layer can be in advance each number in the first data Layer
Different Hash forwarding values are distributed according to node, then it, can be according to target data after Agent layer receives the target data in such as table 1
" Location " value, Hash translation is obtained by preset first hash algorithm as a result, if the Hash translation result with for certain
The Hash forwarding values of one back end distribution are identical, then distribute target data to the back end.Alternatively, can also be first
The first hash algorithm of configured in advance and Hash forward the value set (Kazakhstan of different data node in each back end in data Layer
Without intersection between uncommon forwarding value set), then it, can be by target data after Agent layer receives the target data in such as table 1
" Location " value is advertised to all back end in the first data Layer, and each back end should according to the first hash algorithm
" Location " value be converted to Hash translation as a result, and the Hash forwarding values sets match with itself, wherein there is usually one
Back end can be with successful match, and back end declaration at this time receives target data.Hash about the second data Layer forwards
Process can realize that similar to the above process, details are not described herein again by preset second hash algorithm.
