Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention pre-sets the global image inheritance relationship for the image corresponding to the object to be read and written, obtains the metadata of the corresponding source object of the object to be read and written based on the inheritance relationship of the global image, calculates the consistent hash value according to the metadata, and obtains the Read and write the consistent hash node where the source object corresponding to the object is located, and read and write on the above node. Therefore, the read-write path can be shortened and the performance of the clone image can be improved.

As shown in FIG. 1 , the system architecture 100 may include a server 105 , a network 102 and terminal devices 101 , 102 , 103 . The network 104 serves as a medium for providing communication links between the server 105 and the terminal devices 101 , 102 , 103 . Network 104 may include various connection types, such as wires, wireless communication links, or fiber optic cables, among others. The terminal devices 101, 102, and 103 can be various electronic devices that have a display screen, can download application software, and can perform data reading and writing, including but not limited to smart phones, tablet computers, laptop computers and desktop computers, etc. , the client can use the terminal devices 101, 102, 103 to interact with the server 105 through the network 104 to receive or obtain information and the like.

It should be understood that the numbers of mobile terminals, networks, and devices in FIG. 1 are only illustrative, and there may be any number of mobile terminals, networks, and servers according to implementation requirements.

As shown in FIG. 2 , it is a flowchart of an embodiment provided by the method for improving the performance of a clone image according to the present application. The above-mentioned method for improving the performance of the clone image includes steps:

S201. According to the obtained object to be read and written, determine whether the image corresponding to the object to be read and written has a preset global image inheritance relationship, where the global image inheritance relationship includes an inheritance relationship between a source image and a clone image.

In this embodiment, the method for improving the performance of cloning and mirroring runs on an electronic device (for example, the mobile terminal shown in FIG. 1 ). Among them, the above-mentioned objects to be read and written can be obtained by the user when operating the image to be read and written. s position. The mirror images corresponding to the objects to be read and written may be document files, application files or other types of files, and the objects to be read and written may be objects in document files, application files or other types of files. What needs to be understood is that mirroring is a form of file storage, and multiple files can be made into a mirroring file. The above-mentioned objects to be read and written are part of the mirroring, and the objects are components of the mirroring. A mirroring consists of multiple sizes Consistent objects are composed according to certain rules. For example, a 1G mirror image can be composed of 256 4M objects according to rules. The above rules can be sequence rules, that is, 256 objects are sorted and associated according to 0-255. When the 12M556K reads and writes, that is, it is greater than 3 4Ms and less than 5 4Ms, it is to read and write the No. 4 object. The device used to obtain the object to be read and written can be a terminal device capable of reading and writing data, such as a mobile phone, a tablet, and a computer. The above-mentioned terminal device can interact with the server where the image is located through the network.

Specifically, the above-mentioned global image inheritance relationship can be understood as the parent-child relationship of the global image, that is, the relationship between a source object and multiple child objects. The above-mentioned inheritance relationship can also include the clone path of the clone image, and the clone image can be found through the clone path The parent image (source image), for example: image A' is the clone image of the source image A, and the source image A of the clone image A' is found through the global image inheritance relationship, and the global image inheritance relationship is used to record the relationship between the source image and the clone image clone relationship. In this way, the path for reading and writing the object to be read and written is shortened.

S202. If there is a global mirror inheritance relationship, obtain the metadata of the source object corresponding to the object to be read and written according to the global mirror inheritance relationship, and the metadata includes the consistent hash node used to calculate the source object corresponding to the object to be read and written. Information.

In this embodiment, the above metadata may be the object name corresponding to the object to be read and written in the source image, for example: the object to be read and written is A'0 in the clone image, and the object corresponding to the source image is A0, Then the metadata of the object to be read and written can be an array of A0-A′0. The above metadata can be an array or a key-value relationship including A0 and A'0. For example, if you read and write A'0, you will find the source image of A'0 as A and the displacement of A'0 according to the global inheritance relationship. is 0, then the displacement of the corresponding object in the source image is also 0, and the source object is A0. Perform hash calculation on A0 to get the hash value of the source object A0. Through this hash value, the consistent hash node where the source object is located can be obtained, that is, the object to be read and written shares a hash value with the source object A0 , so the hash value corresponding to A0 is found through the metadata as the object to be read and written, rather than A'0 of the object to be read and written is hashed. Therefore, it is possible to find the consistent hash of the source object through the metadata, and avoid using A'0 to obtain other nodes, resulting in longer read and write paths when reading and writing.

Specifically, as shown in Figure 2a, a schematic diagram of a hash ring structure is provided. For consistent hashing, it can be understood as a hash ring composed of N points, such as ^2-32 points, and N represents the number of points that make up the hash ring. The number of points, the corresponding hash value can be hash(A0)%N). Determine an initial point on the hash ring, for example: set point O as the initial point, then the first point on the right side of point O represents 1, and the first point on the left represents 2 ³² -1. As shown in Figure 2b, suppose there are three storage servers used to store objects, namely server A, server B, and server C. Then, these three servers will have their own IP addresses, and their respective IP addresses will be hashed. Greek calculation, that is, hash (IP address of the server) % 2 ³² , according to the calculated value, corresponding to the value on the hash ring, will get the positions of servers A, B, and C mapped on the hash ring, which can be Distributed in clockwise order. Afterwards, hash calculation can be performed on the object to be stored, and the name of the object can be used as the key value, that is, hash (object name) % 2 ³² . According to the calculated value, which corresponds to the value on the hash ring, the object Mapped to the hash ring, as shown in Figure 2c. For example: the calculated values are objects 1, 2, 3, and 4 respectively, then objects 1, 2, 3, and 4 are mapped on the hash ring together with servers A, B, and C. If objects 1 and 2 on the hash ring are located between server A and server C and stored clockwise, objects 1 and 2 will be stored on the node where server A is located. If object 3 is located between server A and server B , it will be stored on the node where server B is located, and if object 4 is located between server B and server C, it will be stored on the node where server C is located. In this way, through the global mirror inheritance relationship, consistent hash calculation is performed on metadata, which shortens the path for reading and writing objects to be read and written.

S203. Calculate the consistent hash value according to the metadata, and obtain the consistent hash node where the source object corresponding to the object to be read and written is located.

Among them, the consistent hash value is obtained according to the consistent hash algorithm. The consistent hash algorithm is a modulo algorithm, that is, the operation of taking the remainder of the value, so as to ensure that the hash value is an integer, for example: there is There are 3 nodes, and object 0, object 1, and object 2 are respectively stored in these 3 nodes, then the remainder obtained by taking the modulus of object 0 is 0, and the remainder obtained by taking the modulo of object 1 is 1, and the remainder of object 1 is 1. 2 If the remainder obtained by taking the modulo is 2, store object 0 in node 1, store object 1 in node 2, and store object 2 in node 3. If there is object 3, the remainder obtained by modulo is 0, then store Enter node 1.

Specifically, the metadata is calculated through the consistent hash algorithm. Since the metadata includes the information used to calculate the consistent hash node where the source object is located, that is, the value obtained through the consistent hash calculation of the metadata, that is is the value of the node where the source object is located, so as to obtain the consistent hash node where the source object is located. It can be understood that the object to be read and written can be a cloned object, and the metadata of the cloned object can be the key of the source object, and the name of the source object can be the value. In this way, when storing the source object, the value of the source object is used for hashing, and the hashing is performed according to the metadata of the object to be read and written. The value corresponding to the key of the source object, that is, hashed by the value of the source object. Hash the same value to get the same hash value, so as to get the node where the source object of the object to be read and written is located.

S204, read and write on the consistent hash node where the source object corresponding to the object to be read and written is located.

In the embodiment of the present invention, the node of the source object is calculated by a consistent hash algorithm. Through the metadata of the object to be read and written, the read-write node accessed by the user is the storage node of the source object. On this node To read and write, it can be determined that the node must have the data of the source object, and the data of the source object cannot be migrated to complete the read and write.

The present invention pre-sets the global image inheritance relationship for the image corresponding to the object to be read and written, obtains the metadata of the corresponding source object of the object to be read and written based on the inheritance relationship of the global image, and uses the metadata as the calculation of the consistent hash algorithm The consistent hash value is calculated from the data, and the consistent hash node where the source object corresponding to the object to be read and written is located can be obtained from the consistent hash value. Then, the object to be read and written will be processed on the consistent hash node. read and write. Therefore, based on the preset global image inheritance relationship, you can finally find the consistent hash node where the source object of the object to be read and written is located, and read and write on the consistent hash node, which can shorten the read and write path and improve the performance of the clone image .

Further, as shown in FIG. 3, after obtaining the object to be read and written, the above method further includes steps:

S301, setting the data corresponding to the source image;

S302, generating a clone image by cloning the data corresponding to the set source image;

S303. Record the formation paths of the source image and the clone image, and make the source image and the clone image form a global image inheritance relationship based on the paths.

Specifically, set the inheritance relationship of the global image. Specifically, it can take a snapshot of the source image so that the data in the source image cannot be modified. According to the data of the source image, one or more clone images are cloned, and the clone image and the source image are recorded. The cloning path, that is, which source object the above clone image is cloned from. For example, if the clone image of source image A has Aa and Ab, record that Aa and Ab are cloned from source image A, forming the global image inheritance relationship of source image A.

In a possible implementation embodiment, the global image inheritance relationship can be recorded in a form, and the inheritance relationship between the source image and the clone image can be queried through the above form; the global image inheritance relationship can also be recorded in the relationship tree, The root node of the clone image can be queried through the relationship tree.

In this way, by cloning the source image to generate a clone image, and then recording the clone path for generating the clone image, it is beneficial to form a global image relationship between the source image and the clone image.

Further, as shown in Figure 4, the above method also includes steps:

S401. Based on the set global image inheritance relationship, set metadata for associating the clone object in the clone image with the source object of the corresponding source image;

S402. Obtain a source object corresponding to the cloned object through metadata, where the source object is calculated as a consistent hash;

S403. Store the clone object on the consistent hash node calculated by the source object corresponding to the clone object.

In the embodiment of the present invention, the above-mentioned metadata may be an array or a key value describing the relationship between the cloned object and the source object, for example: the name of the source object is A001, the name of the cloned object may be B001, where A and B may be respectively is the name of the source image and the clone image, 001 can be the displacement value of the first object in the image, A001 indicates the first object in the above image, and B001 clone indicates the first cloned object in the clone image. The name of the cloned object can be indexed with the name of the source object, for example: the name "A'0" of the cloned object is indexed to the name "A0" of the source object, and when the cloned object is searched, it can be indexed to "A0 ", perform a consistent hash on "A0", so as to find the node where the source object of the cloned object is located.

Specifically, in order to make the cloned object and the source object on the same node, the name of the source object can be obtained through the metadata, and the name of the source object is used as the name of the consistent hash calculation, that is, the consistent hash value of the cloned object is hash(name of source object) %N. Applying consistent hashing to store cloned objects can be understood as applying a consistent hashing algorithm (hash(name of the cloned object)%N) to the metadata of the cloned object in the cloned image to calculate the consistency of the cloned object Hash value, according to the consistent hash value, store the cloned object on the corresponding location node. The location node can be understood as the corresponding storage or server. On the hash ring, there can be multiple location nodes to form a storage cluster or Server cluster.

What needs to be understood is that in the consistent hashing algorithm, if you hash the same key, you get the same value, and if you hash different keys, you may get different values, for example: "A0" is hashed consistently to get The value of is not necessarily equal to the value obtained by consistent hashing of "A0 clone", "A1" or "A0 clone". The larger N is, the lower the probability of getting the same value.

In this way, when searching for a cloned object, obtain the source object through the metadata and perform consistent hash calculation to obtain the stored consistent hash node, and then you can find the node where the cloned object is stored without searching for another node. The read-write path is further shortened, and the performance of the clone image is improved.

Further, as shown in FIG. 5, the above steps of S204 specifically include:

S501. When writing data on the consistent hash node corresponding to the source object of the object to be read and written, the data is written in an incremental writing manner, and the data corresponding to the source object of the index object to be read and written is supplemented to generate a new object.

In the embodiment of the present invention, when it is necessary to write to the object to be read and written, incremental writing is performed on the node of the source object, that is, only the data to be written is written, and there is no need to copy the data in the source object for rewriting For example, if the data of the source object is 4M, if you need to write 4K data, you only need to write 4K to the node without copying and writing 4M to the node, and the rest of the data will be indexed from the source object The data is indexed into a new object to form a new object with the 4K data.

In this way, write amplification can be avoided by directly writing the data to be written without copying and writing the data of the source object.

Further, as shown in Figure 6, the above method also includes:

S601, judging whether there is metadata based on the global image inheritance relationship in the new object;

S602. If metadata based on the inheritance relationship of the Global Image exists in the new object, perform consistent hash storage on the new object according to the metadata of the inheritance relationship of the Global Image.

In the embodiment of the present invention, if there is metadata in the object to be read and written, then when writing data to the object to be read and written, keep the original metadata of the object to be read and written unchanged, so as to obtain a file containing the original metadata. new object, the new object may contain metadata based on the inheritance relationship of the global mirror, and use the metadata to perform consistent hash calculation on the new object to obtain and store the consistent hash nodes that need to be stored.

In this way, when the metadata of the object to be read and written based on the global mirror inheritance relationship exists in the new object, the node where the new object is stored can be obtained by directly calculating the metadata, which can shorten the path of reading and writing.

Further, as shown in Figure 7, the above method also includes:

S701. Based on the global image inheritance relationship, set corresponding metadata for the new object;

S702. Based on metadata corresponding to the new object, store the new object through a consistent hash, where the metadata includes information used to calculate the consistent hash node where the source object is located.

In the embodiment of the present invention, the above-mentioned new object can be stored in the same node as the source object, and there is a global mirror inheritance relationship between the new object and the source object. The metadata of the object performs consistent hash calculation on the source object, obtains the node where the source object is stored, and stores the new object on this node.

In this way, it can avoid the need to read the data of the source object from the node where the source object is located because the new object is migrated to other nodes, which will further cause the read-write path to become longer.

Further, as shown in Figure 8, the above method also includes:

S801. After the new object is generated, the object of the index source image and the new object form a new clone image;

S802. Set corresponding metadata for the objects in the new clone image, set the corresponding metadata based on the objects in the new clone image, and store the objects in the new clone image by applying a consistent hash;

S803. Write the new clone image into the global image inheritance relationship, wherein the metadata of the object in the new clone image includes consistent hash node information where the metadata is located.

In this embodiment of the present invention, based on the new object, other objects in the index source image and the new object form a new clone image. The new object of data can include written data, index data and metadata, where the written data can be the data written by the user, the index data can be the data indexed to the source object data, and the metadata refers to the description of the new object The attribute data and metadata include the consistent hash node information of the source object. The index object can be understood as other objects in the source object. The other objects in the source object and the new object to which the data is written form a new clone object.

In this way, according to the new object, other objects in the index source image and the new object form a new clone image, so that the front-end business and the back-end data can be synchronized, and by performing consistent hash calculation on the above metadata, the new Clone storage for objects in mirrors.

The metadata is obtained by setting the consistent hash algorithm for the image in the consistent hash storage system. When it is necessary to modify and read the clone image, the location of the source object in the source image on the hash ring is calculated through the metadata. The location is read and written directly. By associating the clone object with the source object through metadata, the location of the source object can be calculated by using the metadata related to the source object, and the clone object is stored on the node of the source object. When writing data, there is no need to read the source object from the node of the source object to perform a write operation, but directly write to the node of the source object. In this way, the length of the read-write path can be avoided, and the performance of the clone mirror can be improved. At the same time, the problems of data migration and write amplification can also be avoided.
