All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, Fig. 1 is a kind of process flow of the write operation control method based on bedding storage provided by the invention
Figure, this method include：
Step S11：When receiving write operation requests, the type in the corresponding base ponds of data to be written is judged；
It should be noted that memory space, can be divided into different storage levels by bedding storage, also known as classification storage
Not, it is placed the data according to hierarchical storage management strategy in different storage ranks, meets user to processing speed, conveyor
The diverse requirements of width and memory capacity rationally utilize memory space, promotion storage system access performance, reduction totality portion to reach
Affix one's name to the purpose of cost.
It needs to establish different disk pools when layer functions are configured, different types of storage medium is configured.Based on this, divide
The distributed file system of layer storage at least needs 3 ponds, 1 metadata pond, 1 standby pond, 1 cache pool, wherein, 1
A pond corresponds to a kind of redundancy rule, and general metadata pond is copy pond, and standby pond is to entangle to delete pond or copy pond, cache pool and be
Copy pond.Caching of the cache pool as standby pond, for client, cache pool is sightless.
In addition, hierarchical storage management strategy here can support the corresponding data of read operation request that can be accessed according to nearest
The mechanism that time is upgraded：For read operation request, if it is the data in last access time, data are upgraded, it is no
Do not upgrade then.The mechanism reduces the frequency of moving back of data, reduces unnecessary data and moves back caused system loss, simultaneously
Also improve the service life of high-performance storage device.Hierarchical storage management strategy can also support the height based on memory space
Water level method, high-low water level method require to monitor storage device in real time using space, judge making for high-performance storage device
Whether reach certain watermark threshold with space, when use space reach watermark threshold when triggering perform data migration operation.
Step S12：If pond is deleted in base ponds to entangle, the type of the corresponding write operation of write operation requests is judged, grasped when writing
When being write as covering, data write-in cache ponds are written into, and base ponds are written in data to be written in the form of entangling and delete；Such as
Fruit base ponds are copy pond, then are written into data write-in cache ponds, and base is written in data to be written in the form of copy
Pond.
Specifically, it is contemplated that entangle and deleted rolling back action, for example entangle and delete 4+2, a data are cut into 4 parts, generate 2 parts of verifications
The disk of 6 nodes can be written in code, 6 parts of data, and 6 divided datas are all write as work(and are just counted as work(, if the write-in failure of some node,
Entire write operation is exactly failure, it is necessary to roll back to the state before write-in, the node that otherwise will be had is new data, is had
Node is the situation of legacy data, causes the data preserved on disk and practical data inconsistent.
Therefore, base ponds are when entangling to delete pond, need the type of the corresponding write operation of write operation requests for judging to receive, when
When write operation is write for covering, returned, and data to be written are acted on behalf of in the form of entangling and deleting after being written into data write-in cache ponds
Base ponds are written, it is seen then that this partial data preserved in cache ponds and base ponds is consistent, so as to reduce cache ponds
Data Migration pressure during water level is reached using space so that distributed file system can keep a smoother performance.
In addition, under writeback patterns, no longer waited when caching is not hit by, in the application the object from base ponds promoted (promote) to
In cache ponds, cache ponds are then written, but directly writes the data to cache ponds and acts on behalf of write-in base ponds, reduces and writes
The delay of operation improves the performance of write operation.It is write if write operation is not covering, for example is that modification is write, then continue to use existing skill
The method of art, judges whether caching hits, and during cache hit, the data to be modified directly in modification cache ponds, caching is not hit by
When, data to be modified are promoted from base ponds to cache ponds, data to be modified are changed in cache ponds.
Specifically, copy is not needed to data slicer, and write-in is all the whole complete data of part, has a data to be written
Even if success success, without rolling back action, so the type without distinguishing write operation.Based on this, when base ponds are copy ponds, directly
It connects and is returned, and data to be written are acted on behalf of in the form of copy write-in base ponds after being written into data write-in cache ponds.
This partial data preserved in cache ponds and base ponds is consistent, reduce cache ponds using space reach water level when
Data Migration pressure so that distributed file system can keep a smoother performance, mitigate distributed file system
The defects of initial performance is high, follow-up performance is low.
The present invention provides a kind of write operation control method based on bedding storage, including：Receiving write operation requests
When, judge the type in the corresponding base ponds of data to be written；If pond is deleted in base ponds to entangle, judge that write operation requests are corresponding
The type of write operation when write operation is write for covering, is written into data write-in cache ponds, and data to be written are deleted to entangle
Form write-in base ponds；If base ponds are copy pond, data write-in cache ponds are written into, and data to be written
Base ponds are written in the form of copy.
The high follow-up performance of middle distributed file system initial performance is low compared with the prior art, in the application client to
Write operation is initiated in cache ponds, when reaching the preset standard of base ponds type and write operation type, is written into data write-in
Cache ponds, while data to be written write-in base ponds so that this partial data preserved in cache ponds and base ponds is one
It causes, so as to reduce Data Migration pressure when cache ponds use space arrival water level, distributed file system is made to keep one
A smoother performance, improves user experience.
