Detailed Description

Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness. The technical scheme of the application obtains, stores, uses, processes and the like the data, which all meet the relevant regulations of national laws and regulations.

The distributed event storage and stream processing platform acts as a high throughput distributed messaging system and plays an important role in the data transmission process. In a distributed system, each Partition (Partition) has multiple copies, one copy is elected as a leader (leader) copy of the current Partition, and is responsible for reading and writing data, and the other copies are backed up as follow-up (follower) copies. If the leader copy is down or the network is abnormal, a new leader copy needs to be reelected. As one example, the distributed event storage and stream processing platform includes a Kafka cluster.

The Kafka cluster contains one or more servers called proxy nodes (brooker). The Kafka cluster contains a plurality of producers (producers), a plurality of brookers, a plurality of consumer groups (consumer groups), and a Zookeeper cluster. The Kafka cluster manages cluster configuration through Zookeeper, producer publishes messages to the broker using push (push) mode, and consumer subscribes to and consumes messages from the broker using pull (pull) mode.

In the process of upgrading software, all proxy nodes need to be shut down for upgrading. The process of upgrading the software needs to take a long time.

In order to solve the problem that software upgrading takes a long time, the following technical scheme in the embodiment of the invention can be adopted.

Referring to fig. 1, fig. 1 is a schematic flow chart of a software upgrading method according to an embodiment of the present invention, where a plurality of proxy nodes process read-write requests and install new software to implement software upgrading. As shown in fig. 1 and 100, the method specifically comprises the following steps:

s101, setting proxy nodes in available areas of different partitions, and setting copies of the proxy nodes in the different available areas.

In an embodiment of the invention, the proxy node is used for processing read-write requests. As one example, the proxy node includes a kafka server. And the proxy node receives a processing read-write request sent by the user. The available area is included in each Partition (Partition). It will be appreciated that the available area is a preset location in the partition. In the availability zone, a copy of the proxy node may be set. As an example, the available area is an area corresponding to the application end. As an example, the application terminal 1 corresponds to the available area 1; the application end 2 corresponds to the available area 2.

Specifically, proxy nodes are set in the available areas of different partitions, and copies of proxy nodes are set in the different available areas. If proxy nodes are arranged in the available areas of different partitions, software upgrading can be realized in the available areas. Copies of the proxy node are set in different available areas, meaning that the proxy node can backup data in the available areas.

The available zones and/or copies are used to achieve fault tolerance at the zone level. As one example, a Kafka agent is divided into three distinct partitions, each containing 16 agent nodes. That is, 16 proxy nodes are set in the available area of one partition. Each proxy node has a corresponding copy. In the event of failure of some of the available regions, only the proxy nodes and copies of some of the available regions are affected, and not all of the proxy nodes and all of the copies.

Referring to fig. 2, 200, fig. 2 is a schematic diagram of a proxy node according to an embodiment of the present invention. The available zones in FIG. 2 include zone1, zone2, and zone3. 4 proxy nodes are set in each available area. Specifically, proxy node 0, proxy node 3, proxy node 6, and proxy node 9 are set in zone 1; setting a proxy node 1, a proxy node 4, a proxy node 7 and a proxy node 10 in zone 2; proxy node 2, proxy node 5, proxy node 8, and proxy node 11 are set in zone3.

In one embodiment of the present invention, the number of proxy nodes is set in the available area, and may be preset based on the actual application scenario. As one example, the number of available area proxy nodes is set based on the number of kafka service proxies. Such as: the number of agent nodes is the same as the number of kafka service agents.

In one embodiment of the invention, a method of performing a software upgrade may be employed with a script. Specifically, scripts are used to set proxy nodes in the available areas of different partitions, and copies of proxy nodes are set in the different available areas. The adoption of script reduces the chance and error of manual intervention. The process may also be reviewed and refined periodically to ensure its efficiency and reliability. As one example, the scripts include shell scripts and/or python scripts.

In one embodiment of the invention, a copy of a topic is taken as a copy of a proxy node, and the copies of the proxy node are arranged in different available areas. Wherein the different available areas include different available areas than the available areas where the proxy node is located. In this way, even if a proxy node in one available region is closed, the proxy node is not affected to process data to achieve a partition upgrade because there is a copy of the proxy node in the other available region.

Referring to fig. 3, 300, fig. 3 is a schematic diagram of a copy of an available area storage proxy node according to an embodiment of the present invention. The usable area of fig. 3 includes: zone-A, zone-B and zone-C. Copies of topic (topic) 1 and topic2 were stored in zone-A, zone-B and zone-C, respectively. Such as: in zone-A, 3 copies of topic1 and 3 copies of topic2 are stored.

the copy distribution of topic1 is now distributed over three areas. The proxy in zone-A is closed and the proxy node is not affected to process data because there are copies of the proxy node in zone-B and zone-C.

Different proxy nodes are distributed in different available areas of different partitions. The same copies are distributed in different available areas. When the proxy node fails or goes wrong, only a single available area is affected, and the whole cluster is not affected.

S102, after the proxy node installs the new version of software, the proxy node installs the new version of software and the proxy node installs the old version of software, and the read-write request of the available area is received and processed.

Software needs to be upgraded for proxy nodes. The plurality of proxy nodes do not interrupt service, namely receive and process the read-write request of the available area, in the process of upgrading the software. The agent node upgrade software is upgraded one by one to ensure continuity and availability of service.

Specifically, after the new version of software is released, the new version of software is installed on one or more proxy nodes. Wherein, the proxy node for installing the new version of software can be determined based on the available area. As one example, a proxy node to install new version of software is selected based on the importance of the availability zone. Such as: the importance of the usable area 1 is higher than that of the usable area 2. The agent node of the new edition software is firstly arranged in the available area 1, and then the agent node of the new edition software is arranged in the available area 2. This facilitates the early installation of new versions of software in important available areas.

As another example, a proxy node for installing new version software is selected based on the amount of data stored in the available region. The larger the amount of data stored in the available area, the more important the proxy node is, and the new software can be installed first.

And when the proxy node installs the new version of software, the proxy node installing the new version of software and the proxy node installing the old version of software run simultaneously, and the read-write request of the available area is received and processed.

Referring to fig. 4 and 400, fig. 4 is a schematic flow chart of a process of simultaneously running a proxy node for installing new version software and a proxy node for installing old version software according to an embodiment of the present invention. The method specifically comprises the following steps:

s401, copying an installation file of the new version of software to install the new version of software in a proxy node.

And downloading and decompressing the installation file of the new software. The installation file of the new version of software is copied to install the new version of software in a proxy node.

It should be noted that, while the proxy node installs the new version of software, the proxy node installing the old version of software may receive and process the read-write request of the available area.

S402, the proxy node for installing the new version of software and the proxy node for installing the old version of software receive and process the read-write request of the available area.

After the proxy node installs the new version of software, the proxy node is called as a proxy node for installing the new version of software. The proxy node for installing the new version of software and the proxy node for installing the old version of software can continuously receive and process the read-write request of the available area.

In the embodiment of fig. 4, the proxy nodes may each install new versions of software. The proxy node for installing the new version of software and the proxy node for installing the old version of software receive and process the read-write request of the available area.

And S103, after the leading copy of the available area is migrated to the proxy node for installing the new version of software, upgrading the proxy node for installing the old version of software to the new version of software.

And the proxy node copy is updated by being migrated to the proxy node on which the new version of software is installed. Specifically, after the leading copy of the available area is migrated to the proxy node for installing the new version of software, the proxy node for installing the old version of software is upgraded to the new version of software. Wherein the leading copy of the available region is determined from the copies of the proxy nodes. As one example, the leading copy of the available region is elected among the copies of the proxy node.

Referring to fig. 5, 500, fig. 5 is a schematic flow diagram of migrating a leader copy according to an embodiment of the present invention. The method specifically comprises the following steps:

S501, searching for a proxy node for installing new software.

After the proxy node installs the new version of software, the migration of the copy needs to be considered. First, a proxy node that installs new version software is searched. As one example, a proxy node that installs new version software is searched based on the identity of the new version software.

S502, a migration file is established according to the identification of the proxy node for installing the new software, so that the leading copy of the available area is migrated to the proxy node for installing the new software.

After searching the proxy node for installing the new version of software, establishing a migration file according to the identification of the proxy node for installing the new version of software. As one example, the migration file is a json file.

And migrating the leading copy of the available area to a proxy node for installing the new software according to the migration file. After the leader copy is migrated to the proxy node where the new version of software is installed, a new leader copy is selected from the follower copies. Further, the leader copy is migrated again to the proxy node where the new version of software is installed.

In the embodiment of FIG. 5, the leading copy of the available region is migrated to the proxy node that installed the new version of software based on the migration file.

In one embodiment of the invention, it is necessary to confirm that all leader copies are migrated to the proxy node where the new version of software is installed. Specifically, based on the identification of the leader copies of the available regions and the identification of the leader copies migrated to the agent node that installed the new version of software, it is determined that all of the leader copies of the available regions have been migrated to the agent node that installed the new version of software.

As one example, if the identity of the leading copies of all available regions is the same as the identity of the leading copies migrated to the proxy node that installed the new version of software, then it is determined that all leading copies of the available regions have been migrated to the proxy node that installed the new version of software.

After confirming that all the leading copies are migrated to the proxy node for installing the new version software, the proxy node for installing the old version software is updated by the new version software.

Referring to fig. 6, fig. 6 is a schematic flow chart of updating proxy nodes with new versions of software according to an embodiment of the present invention. The method specifically comprises the following steps:

s601, copying an installation file of the new version of software to install the new version of software on an agent node for installing the old version of software.

After all the leading copies of the available areas are migrated to the proxy node for installing the new version of software, the need of accelerating the upgrade of the software of the proxy node is described. Then the installation file of the new version of software may be copied to install the new version of software at a proxy node where the old version of software is installed.

S602, after the proxy node for installing the old version of software is updated to the new version of software, the new version of software is installed on the next proxy node for installing the old version of software.

After an agent node for installing old version software is upgraded to new version software, the next agent node for installing old version software can be continuously upgraded. That is, the new version of software is installed on the next proxy node on which the old version of software is installed.

In the embodiment of FIG. 6, after all of the leader copies have been migrated to the proxy node that installed the new version of software, the new version of software may be installed for the proxy node that installed the old version of software.

In one embodiment of the invention, in order to accelerate the speed of upgrading software by the proxy node, the proxy node for installing old version software can be closed, and the proxy node for installing old version software in different available areas can be upgraded to new version software.

After the leading copy of the available area is migrated to the proxy node for installing the new software, the proxy node for installing the new software provides service. The proxy node for installing the old version software is not required to provide service, the proxy node for installing the old version software is closed firstly, and the proxy nodes for installing the old version software in different available areas can be updated to the new version software. In this way, the software of multiple proxy nodes can be upgraded at once.

As one example, after migrating the leading copy of the available region onto the proxy node that installed the new version of software, the proxy node that installed the old version of software includes proxy node a in available region A, proxy node B in available region B, and proxy node C in available region C. Agent node a, agent node b, and agent node c may be shut down first, and then upgraded to new versions.

In one embodiment of the invention, to avoid negatively impacting the production environment during proxy node upgrades, load control measures are implemented to ensure that proxy nodes do not overload by limiting the number of client connections and traffic. The available region read-write request may also be allocated before the upgrade receives and processes the available region read-write request.

Specifically, according to the number of the read-write requests currently processed by the proxy node, the read-write requests of the available area are distributed to the proxy node for loading new version software or the proxy node for loading old version software, so that the load balance of the proxy node is ensured.

As one example, multiple read and write requests need to be processed for each proxy node. The read-write requests of the available area may be allocated based on the number of currently processed read-write requests of the proxy node.

Such as: the read-write requests of the available area are allocated based on the principle that the number of the read-write requests processed by each node is the same. The proxy node of the new version of software comprises a node a and a node b, and the proxy node for installing the old version of software comprises a node c. And counting the number of the current processing requests of each node. The same number of read-write requests processed by each node is preset. Node a currently processes 4 read-write requests; node b currently processes 3 read-write requests; node c may send 4 read-write requests from the current process to node b for processing.

And the following steps: considering that the proxy node for installing the old version of software also needs software upgrade, the number of the proxy nodes for setting the new version of software to process the read requests is greater than the number of the proxy nodes for the old version of software to process the read requests. That is, the read-write requests of the available area are allocated based on the principle that the number of read requests processed by the agent node of the new version of software is greater than the number of read requests processed by the agent node of the old version of software. The proxy node of the new version of software comprises a node a and a node b, and the proxy node for installing the old version of software comprises a node c. And counting the number of the current processing requests of each node. The same number of read-write requests processed by each node is preset. Node a currently processes 4 read-write requests; node b currently processes 3 read-write requests; node c may send the newly received read-write requests of the available area to node b for processing, if 3 read-write requests are currently processed.

In one embodiment of the invention, copies of the proxy node are set in different availability zones to handle traffic through the copies. Specifically, 3 copies of the proxy node are set in one available area. Through multiple practices, the data parallel processing efficiency is high and the data load balance is met under the condition that the number of copies of the proxy node is 3 in consideration of data parallel processing and data load balance in the software upgrading process.

As an example, in a Kafka cluster, each Topic (Topic) may be divided into multiple partitions, each of which may be assigned to a different proxy node process to enable parallel processing of data. Each Topic is divided into 4 partitions, and each partition is replicated and synchronized on 3 copies within one available area, respectively, to improve parallelism and reliability.

Specifically, after each topic is divided into 4 partitions, each partition is respectively allocated to 3 copies in each available area for replication and synchronization. And 3 copies, wherein one copy is a leader (leader) copy and is responsible for processing read-write requests and data copying, and the other two copies are follower copies and are responsible for copying data of the leader copies. Thus, each available area can be processed and copied on 3 copies at the same time, and parallel processing and load balancing of data are realized.

3 copies of the proxy node are arranged in one available area, so that the parallelism of the Kafka cluster is improved to 3 times, and meanwhile, the reliability and the availability of data are guaranteed. When the leader copy fails, the Kafka cluster automatically performs leader election, and reliability and consistency of data are ensured.

In the embodiment of the invention, the proxy nodes are arranged in the available areas of different partitions, and the copies of the proxy nodes are arranged in the different available areas; after the proxy node installs the new version of software, the proxy node installs the new version of software and the proxy node installs the old version of software, and receives and processes the read-write request of the available area; and after the leading copy of the available area is migrated to the proxy node for installing the new version of software, upgrading the proxy node for installing the old version of software to the new version of software. The proxy nodes are upgraded one by one, and the leader copy is migrated based on the upgraded proxy nodes. After the leading copy completes migration, the proxy node for installing the old version of software is started again for upgrading. In the upgrading process, the proxy node can still process the read-write request, so that the time spent on software upgrading is shortened.

In the whole updating process, the read-write request can be smoothly transferred between the proxy node for installing the new version software and the proxy node for installing the old version software. In addition, as the copies of the proxy nodes are arranged in different available areas, all data can be reserved, and the situation of data loss can not occur. Meanwhile, the proxy node is adopted to realize rolling software upgrading, so that the performance and stability of the whole cluster are not affected in the software upgrading process.

Referring to fig. 7, fig. 7 is a schematic main structural diagram of a software upgrade apparatus according to an embodiment of the present invention, where the software upgrade apparatus may implement a software upgrade method, as shown in fig. 7, 700, and the software upgrade apparatus specifically includes:

For example, embodiments of the present disclosure include a computer program product comprising a computer program embodied on a computer readable medium, the computer program comprising program code for performing the method shown in the flow chart. In such an embodiment, the computer program may be downloaded and installed from the network via the communication portion 909 and/or installed from the removable medium 911. The above-described functions defined in the system of the present invention are performed when the computer program is executed by a Central Processing Unit (CPU) 901.

The computer readable medium shown in the present invention may be a computer readable signal medium or a computer readable storage medium, or any combination of the two. The computer readable storage medium can be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or a combination of any of the foregoing. More specific examples of the computer-readable storage medium may include, but are not limited to: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. In the present invention, however, the computer-readable signal medium may include a data signal propagated in baseband or as part of a carrier wave, with the computer-readable program code embodied therein. Such a propagated data signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination of the foregoing. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: wireless, wire, fiber optic cable, RF, etc., or any suitable combination of the foregoing.

The flowcharts and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams or flowchart illustration, and combinations of blocks in the block diagrams or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.

The modules involved in the embodiments of the present invention may be implemented in software or in hardware. The described modules may also be provided in a processor, for example, as: a processor includes a setup module, a processing module, and an upgrade module. Where the names of the modules do not constitute a limitation on the module itself in some cases, for example, the setup module may also be described as "for setting up proxy nodes in the available areas of different partitions, and for setting up copies of proxy nodes in different available areas".

As another aspect, the present invention also provides a computer-readable medium that may be contained in the apparatus described in the above embodiments; or may be present alone without being fitted into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to include:

According to the technical scheme of the embodiment of the invention, proxy nodes are arranged in the available areas of different partitions, and copies of the proxy nodes are arranged in the different available areas; after the proxy node installs the new version of software, the proxy node installs the new version of software and the proxy node installs the old version of software, and receives and processes the read-write request of the available area; and after the leading copy of the available area is migrated to the proxy node for installing the new version of software, upgrading the proxy node for installing the old version of software to the new version of software. The proxy nodes are upgraded one by one, and the proxy nodes can still process read-write requests in the upgrading process, so that the time consumption of software upgrading is shortened.

The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.

In the technical scheme of the invention, the aspects of acquisition, analysis, use, transmission, storage and the like of the related user personal information all meet the requirements of related laws and regulations, are used for legal and reasonable purposes, are not shared, leaked or sold outside the aspects of legal use and the like, and are subjected to supervision and management of a supervision department. Necessary measures should be taken for the personal information of the user to prevent illegal access to such personal information data, ensure that personnel having access to the personal information data comply with the regulations of the relevant laws and regulations, and ensure the personal information of the user. Once these user personal information data are no longer needed, the risk should be minimized by limiting or even prohibiting the data collection and/or deletion.

User privacy is protected, when applicable, by de-identifying the data, including in some related applications, such as by removing a particular identifier (e.g., date of birth, etc.), controlling the amount or specificity of stored data (e.g., collecting location data at a city level rather than at a specific address level), controlling how the data is stored, and/or other methods.
