Detailed ways

In order to make the technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

It will be understood that the terms "first," "second," and the like, as used herein, may be used to describe various elements, and the elements are not limited by these terms unless specifically stated. These terms are only used to distinguish one element from another. For example, the first primary cluster may be referred to as a second primary cluster without departing from the scope of the present application, and similarly, the second primary cluster may be referred to as a first primary cluster.

FIG. 1 is an application environment diagram of a data request processing method provided in an embodiment. As shown in FIG. 1 , in the implementation environment, as shown in the foregoing figure, the client 10, the computer device 20, and the first main cluster 31 are included. The first standby cluster 32 corresponding to the first primary cluster 31, the second primary cluster 41, and the second standby cluster 42 corresponding to the second primary cluster 41. It can be connected via the network. The primary cluster and the standby cluster are generally distributed in different cities, so that when the primary cluster fails, the standby cluster responds to the service. The domain names of the first primary cluster 31 and the second primary cluster are different, but in the external service, an identical domain name may be set, and the domain name resolution result of the same domain name points to the IP address of the computer device 20. When the client issues a data request, for example, requesting to download a file, the computer device 20 receives the data request, obtains the corresponding primary cluster domain name according to the target data identifier in the data request, and then sends a response to the primary cluster according to the primary cluster domain name and the data request. The request causes the corresponding primary cluster to respond and return a response message, and sends the response information to the client. If the primary cluster fails to respond, the proxy server sends a response request to the standby cluster according to the standby cluster domain name and the data request, and receives the response information returned by the standby cluster and sends the response information to the client.

The computer device 20 may be a stand-alone physical server or terminal, or may be a server cluster composed of multiple physical servers, and may be a cloud server that provides basic cloud computing services such as a cloud server, a cloud database, a cloud storage, and a CDN. The client can be a smartphone, a tablet, a laptop, a desktop computer, a smart speaker, a smart watch, a server, etc., but is not limited thereto. Client 10 and computer device 20, computer device 20 and first primary cluster 31, first standby cluster 32, second primary cluster 41, second standby cluster 42, first primary cluster 31 and first standby cluster 32, and second The primary cluster 41 and the second standby cluster 42 can be connected through a network. There may be one or more clusters, for example, there may be 10, which is not limited by the embodiment of the present application.

As shown in FIG. 2, in some embodiments, a data request processing method is provided, which may be applied to the computer device 20, and may specifically include the following steps:

Step S202, receiving a data request sent by the client, where the data request carries the target data identifier.

The data request may include requesting to download data in the cluster, requesting deletion of data in the cluster, or requesting one or more of uploading data to the cluster. When uploading data to the cluster, the data request also carries the data to be uploaded. The target data identifier can be represented by at least one of data and text. One or more clusters are served externally through a uniform access address. The client receives the access address, such as a domain name or an IP address of a computer device, and sends a data request to the computer device based on the access address. When the input access address is a domain name, the data request is parsed by a DNS (Domain Name System) to obtain an IP address of the computing device 20 to route the data request to the computer device 20 when the input access address is an IP address. The client sends a data request to the computer device 20 based on the IP address.

Step S204, obtaining a corresponding primary cluster and a standby cluster according to the target data identifier.

The correspondence between the data identifier and the cluster may be set in advance, and the correspondence may be a direct correspondence. For example, the data identifier a corresponds to the b cluster. It can also be an indirect correspondence. For example, the calculation rule and the correspondence between the value and the cluster may be set. After the data identifier is obtained, the data identifier is calculated according to the preset calculation rule, and the corresponding value is obtained, and the corresponding primary cluster is obtained according to the correspondence between the value and the cluster. Standby cluster.

In step S206, the running information of the primary cluster is obtained, and the running information includes a normal operation or an abnormal operation.

The running information of the primary cluster can be obtained actively or automatically by the primary cluster. For example, the primary cluster can periodically send heartbeat information to the computer device. If the computer does not receive the heartbeat information of the cluster within a certain period of time, it indicates that the primary cluster is abnormal. In some embodiments, in order to be able to work in time after the primary cluster fails to recover normally, after receiving the data request, the data request may be sent to the primary cluster, and if the response of the primary cluster is not received, The primary cluster is running abnormally.

Step S208: If the primary cluster runs abnormally, send a first response request to the standby cluster according to the data request, where the first response request carries the target data identifier.

The primary cluster abnormality means that the primary cluster cannot respond. If the primary cluster runs abnormally, the first response request is sent to the standby cluster according to the data request. For example, when the data request is downloading data, the first response request for requesting the download data identifier to be the target data identifier is sent to the standby cluster, so that the standby cluster obtains the target data according to the target data identifier, and returns the target data to the computer device. When the data request is to delete data, the first response request for deleting the data identifier to the target data identifier is sent to the standby cluster, so that the standby cluster finds the target data according to the target data identifier, and deletes the target data. When the data request is to store data, the target data identifier and the target data are sent to the standby cluster, so that the standby cluster corresponds to the storage target data and the target data identifier.

In some embodiments, if the primary cluster is running normally, the second response request is sent to the primary cluster according to the data request, the primary cluster responds and returns the second response information, and the computer device returns the second response information to the client.

In some embodiments, the primary cluster and the standby cluster can be synchronized by the remote synchronization program, and the remote synchronization program reads the primary cluster operation record, and synchronizes the operation of the primary cluster to the standby cluster according to the primary cluster operation record.

Step S210: Receive first data response information sent by the standby cluster according to the first response request, and return the first data response information to the client.

The first data response information is information returned by the standby cluster according to the first response request. When the first response request is to download data, the standby cluster obtains the target data according to the target data identifier, and returns the target data to the computer device. When the first response request is to delete data, the standby cluster finds the target data according to the target data identifier, and deletes the target data and returns the first data response information that is successfully deleted. When the first response request is to store data, the standby cluster returns the storage first data response information corresponding to the storage target data and the target data identifier.

In some embodiments, when the first response request is to download data, the standby cluster returns data to be downloaded. When the first response request is uploading data or deleting data, in order to maintain consistency between the primary cluster and the standby cluster, the standby cluster is configured. Returns the first response message requesting an error.

When receiving the data request sent by the client, the data request processing method obtains the corresponding primary cluster and the standby cluster according to the target data identifier, and sends a first response request to the standby cluster when the primary cluster runs abnormally, and receives the standby cluster. And transmitting the first data response information according to the first response request to the client. When the data request is received, the corresponding primary cluster and the standby cluster are obtained according to the target data identifier, and when the primary cluster runs abnormally, the corresponding standby cluster responds according to the data request, so that the service can be externally accessed through the unified access address. The cluster does not need to migrate data, which reduces the workload of the migration and can respond to the standby cluster in time when the primary cluster fails.

In some embodiments, as shown in FIG. 3, step S204 is to obtain a corresponding primary cluster and a standby cluster according to the target data identifier, including:

Step S302, performing a hash operation according to the target data identifier, and obtaining a hash value corresponding to the target data identifier.

Hash calculation is a calculation method for transforming an input of arbitrary length into a certain length by a hash algorithm. The hash algorithm can be MD5 (Message-digest Algorithm 5) algorithm and SHA (Secure Hash Standard, security Greek standard) algorithm, etc., specifically no restrictions. After the target data identifier is obtained, the target data identifier is calculated by using a preset algorithm to obtain a hash value.

Step S304, performing a remainder operation on the hash value and the preset value to obtain a target key value.

After the hash value is obtained, the remainder obtained by dividing the hash value by the preset value is used as the target key value. Expressed as follows: y = mod (x, b), where x represents a hash value. b indicates the preset value, and the specific value can be set according to the actual setting, such as 10000. y represents the target key value. Mod represents the calculation of the remainder. For example, the hash value is 3, the default value is 10000, and 3 is divided by 10000 and the remainder is 3, then 3 is the target key value.

Step S306, obtaining a corresponding primary cluster and a standby cluster according to the target key value.

The correspondence between the target key value and the primary cluster and the standby cluster may be pre-stored, and the corresponding relationship may be that the target key value directly corresponds to the primary cluster and the standby cluster, or may be an indirect correspondence. For example, the primary cluster corresponding to the target key value h is A1, and the standby cluster is A2.

In some embodiments, as shown in FIG. 4, the step of acquiring the corresponding primary cluster and the standby cluster according to the target key value in step S306 includes:

Step S402: Acquire a target cluster identifier corresponding to the target key value according to the correspondence between the key value and the cluster identifier.

The correspondence between the key value and the cluster identifier is set in advance. As shown in Table 1, the correspondence between the key value and the cluster identifier can be stored in the form of a data table. After the target key value is obtained, the key value matching the target key value in the data table is obtained, and the cluster identifier corresponding to the key value matching the target key value is used as the target cluster identifier.

In some embodiments, the correspondence between the key value and the cluster identifier may be stored in the preset storage location. After the target key value is obtained, the storage address corresponding to the preset storage location is obtained, and the key value and the cluster are obtained according to the storage address. The corresponding relationship of the logo. The preset storage location may be limited according to actual needs. For example, in order to improve the speed of acquiring the target cluster identifier, the correspondence between the key value and the cluster identifier may be stored in the cache of the computer device.

Table 1:

键值Key value	集群编号Cluster number
11	cluster1Cluster1
22	cluster1Cluster1
33	Cluster2Cluster2
44	cluster1Cluster1
55	Cluster3Cluster3

Step S404: Acquire a primary cluster and a standby cluster corresponding to the target cluster identifier according to the correspondence between the cluster identifier and the cluster.

The mapping between the cluster ID and the cluster is set in advance. For example, as shown in Table 2, the primary cluster domain name and the standby cluster domain name corresponding to each cluster number are set in advance.

In some embodiments, the relationship between the cluster identity and the cluster IP address can also be stored. For example, the domain name resolution request may be sent to the domain name server according to the cluster domain name information at a preset time or duration, and the correspondence between the storage cluster identifier and the cluster IP address may be obtained after receiving the IP address sent by the domain name server. In this way, each time a connection is established with the cluster, domain name resolution is not required first, which improves the timeliness of responding to data requests.

In some embodiments, after establishing a connection with the cluster and obtaining response information, the computer device can continue to maintain the established network connection to continue to use the network connection to process other data requests, and then release the network connection when the preset time is, for example, one hour later. Connections, thus avoiding the delay caused by the need to create a new network connection each time a response request is sent.

In some embodiments, the database domain name corresponding to the cluster identifier may be stored by the database, and the computer device may periodically read the cluster domain name information and cache it locally.

Table 2:

In some embodiments, as shown in FIG. 5, the data request processing method may further include the following steps:

Step S502, obtaining a weight corresponding to the cluster identifier.

The weights can be customized according to the requirements, or can be calculated by the computer device according to the performance of the cluster, for example, the capacity, so that the load of the cluster corresponds to the performance of the cluster or the number of services externally served by the cluster is adjusted according to actual needs. For example, you can calculate the capacity of a primary cluster as a percentage of the total capacity of the primary cluster, and use the percentage obtained as the weight corresponding to the cluster ID.

Step S504, assigning a corresponding key value to the cluster identifier according to the weight and the preset value, and obtaining a correspondence between the key value and the cluster identifier.

After the weight is obtained, the weight is multiplied by the preset value to obtain the number of key values to be allocated by the cluster identifier, and then the corresponding key value is assigned to the cluster identifier according to the number of key values, and the correspondence between the key value and the cluster identifier is obtained.

For example, the preset value is 10000, the weight corresponding to the A cluster is 0.25, and the weight corresponding to the B cluster is 0.75. The key value is assigned to each cluster according to the weight and the total number, and the number of keys corresponding to the A cluster is 0.25*10000. =2500, so the key value 0~2499 can be assigned to the A cluster. The number of keys corresponding to the B cluster is 0.75*10000=7500, so the key value 2500-9999 is assigned to the B cluster. When the target data identifier is received, the target data identifier is calculated, and a hash value and a preset value of 10000 are obtained. If the remainder is 1 to 2499, the corresponding cluster is the A cluster, and the obtained remainder is obtained. If it is 2500 to 9999, the corresponding cluster is a B cluster.

In some embodiments, as shown in FIG. 6, the step of acquiring the operation information of the primary cluster in step S208 includes:

Step S602, sending a second response request to the primary cluster according to the data request, where the second response request carries the target data identifier.

After receiving the data request, sending a second response request to the primary cluster according to the data request, for example, when the data request is downloading data, sending a second response request to the primary cluster requesting that the download data identifier be the target data identifier, so that The primary cluster obtains target data based on the target data identifier and returns the target data to the computer device. When the data request is to delete data, the second cluster response request for deleting the data identifier to the target data identifier is sent to the primary cluster, so that the primary cluster finds the target data according to the target data identifier, and deletes the target data. When the data request is to store data, the target data identifier and the target data are sent to the primary cluster, so that the primary cluster corresponds to the storage target data and the target data identifier.

Step S604, when receiving the second response information returned by the primary cluster according to the second response request, the running information is normal, and when the second response information returned by the primary cluster according to the second response request is not received, the running information is running. abnormal.

After the second response request is sent, if the second response information returned by the primary cluster according to the second response request is received, the primary cluster operation information is normal. For example, when the second response request is to download data, the primary cluster obtains the target data according to the target data identifier and returns the target data to the computer device. When the second response request is to delete data, the primary cluster finds the target data according to the target data identifier, and deletes the target data and returns the second data response information that is successfully deleted. When the second response request is storing data, the primary cluster returns the storage second data response information corresponding to the storage target data and the target data identifier. When the response information returned by the primary cluster according to the second response request is not received, the obtained primary cluster operation information is a running abnormality.
