Fig. 1 illustrates an exemplary architecture 100 to which the methods and apparatus for dynamically adjusting zone server threads of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105.

The terminal devices 101, 102, 103 may be hardware devices or software that support network connections for data interaction and data processing. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices supporting network connection, information acquisition, interaction, display, processing, and the like, including but not limited to smart phones, tablet computers, e-book readers, laptop portable computers, desktop computers, and the like.

And is not particularly limited herein.
It should be further noted that the method for dynamically adjusting the zone server thread provided by the embodiments of the present disclosure may be executed by a server, may also be executed by a terminal device, and may also be executed by the server and the terminal device in cooperation with each other. Accordingly, each part (for example, each unit, subunit, module, and submodule) included in the device for dynamically adjusting the regional server thread may be all disposed in the server, may be all disposed in the terminal device, and may be disposed in the server and the terminal device, respectively.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. The system architecture may include only the electronic device (e.g., server or terminal device) on which the method of dynamically adjusting the zone server thread is running, when the electronic device on which the method of dynamically adjusting the zone server thread is running does not need to perform data transfer with other electronic devices.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method of dynamically adjusting zone server threads is shown, comprising the steps of:
step 201, determining the running information of the regional server to be adjusted within a preset time period from the current time.
In this embodiment, an execution subject (for example, the server in fig. 1) of the method for dynamically adjusting the regional server thread may determine the operation information of the regional server to be adjusted within a preset time period from the current time.
The time length represented by the preset time period can be specifically set according to the actual situation. For example, the preset time period is characterized by a time length of 30 seconds. The regional Server to be tuned (Region Server) may be any regional Server in the Server cluster. By way of example, the server cluster is an HBase cluster, which is a distributed, column-oriented open-source database. The server of the area to be adjusted is a HRegonServer in the Hbase cluster and is mainly responsible for responding to a user I/O request and reading and writing data into a Hadoop Distributed File System (HDFS). The operation information may be various information representing the information processing capability of the area server to be adjusted, which is exhibited by the area server to be adjusted in the process of executing the operation request issued by the user through the client. For example, the run information includes the number of threads, the load of the server, and the like.
In this embodiment, the execution subject may determine the preset time period from the current time by using a sliding time window. And the time length represented by the sliding time window is the same as the time length represented by the preset time period.
As an example, the execution subject may use, as the operation information of the area server to be adjusted, which is collected within a preset time period from a current time, a start point, a middle point, or an end point of the preset time period.
In some optional implementations of this embodiment, the executing main body may execute the step 201 as follows:
firstly, acquiring operation information of a server in an area to be adjusted based on a preset time interval.
The preset time interval can be specifically set according to actual conditions. For example, the preset time interval is 5 seconds. It is understood that the time length represented by the preset time interval is less than or equal to the time length represented by the preset time period.
Secondly, taking the average value of the running information collected in the preset time period from the current time as the running information of the server in the area to be adjusted in the preset time period.
As an example, the time length represented by the preset time period is 30 seconds, the preset time interval is 5 seconds, and the execution main body may use an average value of the operation information acquired for a plurality of times in the preset time period as the operation information of the area server to be adjusted in the preset time period.
Step 202, determining adjustment information for adjusting the thread of the server in the area to be adjusted according to the running information and the preset limit information.
In this embodiment, the execution main body may determine, according to the operation information and the preset restriction information, adjustment information for adjusting a thread of the server in the area to be adjusted. The preset limiting information represents limiting information set for the operation information of the area server to be adjusted. It is understood that the zone server should operate under the preset restriction information.
In this embodiment, when the value represented by the operation information is lower than the value represented by the preset limit information, the execution main body may determine the adjustment information for expanding the capacity of the thread of the area server to be adjusted, but the value represented by the operation information of the area server to be adjusted after expansion should be still lower than the value represented by the preset limit information; when the value represented by the operation information is not lower than the value represented by the preset limit information, the execution main body may determine adjustment information for performing capacity reduction on the thread of the area server to be adjusted, so that the value represented by the operation information of the area server to be adjusted after capacity reduction is lower than the value represented by the preset limit information.
In some optional implementations of this embodiment, the operation information includes load information and performance information. The load information is used for representing the machine utilization rate of the area server, and the performance information represents the processing time of the area server to the received operation request. The operation request includes various types of requests, and may be, for example, a read request or a write request. It can be understood that, when the processing time of the area server for the received operation request is shorter, the processing performance of the area server is better; the longer the processing time of the area server for the received operation request is, the worse the processing performance of the area server is. That is, the processing time of the received operation request by the zone server is inversely related to the processing performance.
The preset restriction information includes load restriction information and performance restriction information. The load limitation information is limitation information set for the load information of the area server to be adjusted, and the performance limitation information is limitation information set for the performance information of the area server to be adjusted.
The execution main body may execute the step 202 as follows:
first, in response to determining that the machine utilization rate represented by the load information is smaller than the machine utilization rate represented by the load limiting information and that the request processing time represented by the performance information is smaller than the request processing time represented by the performance limiting information, determining adjustment information for expanding the capacity of the thread of the area server to be adjusted.
The utilization rate of the machine represented by the load information of the expanded area server to be adjusted should still be less than the utilization rate of the machine represented by the load limitation information, and the request processing time represented by the performance information should still be less than the request processing time represented by the performance limitation information.
Secondly, in response to determining that the machine utilization rate represented by the load information is not less than the machine utilization rate represented by the load limiting information or that the request processing time represented by the performance information is not less than the request processing time represented by the performance limiting information, determining adjustment information for performing capacity reduction on the thread of the area server to be adjusted.
In some optional implementations of this embodiment, the preset limit information further includes load tolerance information and performance tolerance information. The load tolerance information is used for limiting the difference between the load limiting information and the load information in the area server to be adjusted, and the performance tolerance information is used for limiting the difference between the performance limiting information and the performance information in the area server to be adjusted. It can be understood that, when the difference between the machine utilization rate represented by the load limitation information and the machine utilization rate represented by the load information is greater than the machine utilization rate represented by the load tolerance information, and the difference between the request processing time represented by the performance limitation information and the request processing time represented by the performance information is greater than the request processing time represented by the performance tolerance information, it indicates that the to-be-adjusted area server has the capability of processing more operation requests, and the capacity of the thread of the to-be-adjusted area server can be expanded. Otherwise, it indicates that the area server to be adjusted does not have the capability of processing more operation requests, and the capacity of the thread of the area server to be adjusted is not expanded, so that the thread currently running by the area server to be adjusted processes the received operation request.
Specifically, in response to determining that the machine utilization rate represented by the load information is smaller than the machine utilization rate represented by the load limitation information, the request processing time represented by the performance information is smaller than the request processing time represented by the performance limitation information, the difference between the machine utilization rate represented by the load limitation information and the machine utilization rate represented by the load information is larger than the machine utilization rate represented by the load tolerance information, and the difference between the request processing time represented by the performance limitation information and the request processing time represented by the performance information is larger than the request processing time represented by the performance tolerance information, the adjustment information for performing capacity expansion of a preset step length on the thread of the area server to be adjusted is determined.
It is to be understood that, in this implementation, in response to determining that the machine usage rate represented by the load information is less than the machine usage rate represented by the load limitation information, and the request processing time represented by the performance information is not less than the request processing time represented by the performance limitation information, and the difference between the machine usage rate represented by the load limitation information and the machine usage rate represented by the load information is not greater than the machine usage rate represented by the load tolerance information, or the difference between the request processing time represented by the performance limitation information and the request processing time represented by the performance information is not greater than the request processing time represented by the performance tolerance information, the execution entity does not perform capacity expansion on the thread of the area server to be adjusted, so that the thread currently running by the area server to be adjusted processes the received operation request.
The preset step represents the number of the threads with capacity expansion or capacity reduction in each adjustment process of the threads of the server to be adjusted. Specifically, the preset step length may include a preset capacity expansion step length and a preset capacity reduction step length. The preset capacity expansion step length and the preset capacity reduction step length can be the same or different, and the numerical values represented by the preset capacity expansion step length and the preset capacity reduction step length can be specifically set according to actual conditions. For example, the preset capacity expansion step size and the preset capacity reduction step size are both 5.
And step 203, adjusting the number of threads of the area server to be adjusted according to the adjustment information.
In this embodiment, the execution main body may adjust the number of threads of the server in the area to be adjusted according to the adjustment information.
As an example, when the adjustment information is adjustment information representing capacity expansion of the threads of the area server to be adjusted, the capacity expansion of the number of the threads of the area server to be adjusted is performed; and when the adjustment information is the adjustment information representing the capacity reduction of the threads of the area server to be adjusted, carrying out the capacity reduction on the number of the threads of the area server to be adjusted.
With continued reference to fig. 3, fig. 3 is a schematic diagram 300 of an application scenario of the method for dynamically adjusting a zone server thread according to the present embodiment. In the application scenario of fig. 3, the HBase cluster 301 includes a plurality of zone servers, including zone servers 3011, 3012, and 3013. HBase cluster 301 may receive and process operation requests of various clients. In the process of processing the operation request, each zone server in the HBase cluster 301 dynamically adjusts the processing capability of the zone server according to the operation information of the zone server. Taking the server 3011 as an example, first, the running information of the area server 3011 to be adjusted in a preset time period from the current time is determined. Then, adjustment information for adjusting the thread of the area server 3011 to be adjusted is determined according to the operation information and the preset restriction information. Finally, the number of threads of the area server 3011 to be adjusted is adjusted according to the adjustment information.
In the method provided by the above embodiment of the present disclosure, the operation information of the area server to be adjusted is determined within the preset time period from the current time; determining adjustment information for adjusting the thread of the server in the area to be adjusted according to the operation information and the preset limit information; and adjusting the number of threads of the regional server to be adjusted according to the adjustment information, thereby providing a mechanism for dynamically adjusting the processing capacity of the regional server according to the running information of the regional server and improving the flexibility of adjusting the processing capacity of the regional server.
In some optional implementation manners of this embodiment, the execution main body may further obtain a preset time period, load limitation information, performance limitation information, load tolerance information, performance tolerance information, and a preset step size through a configuration file of the server in the area to be adjusted. The configuration file is a configuration file corresponding to the area server to be adjusted.
In some optional implementations of this embodiment, the executing agent may execute the steps 201 to 203 respectively for various types of operation requests. Specifically, the execution entity executes the following operations for each type of operation request processed by the area server to be adjusted: firstly, determining the running information of the regional server to be adjusted corresponding to the type of operation request within a preset time period from the current time; determining adjustment information for adjusting the thread of the server in the area to be adjusted according to the operation information and the preset limit information; and adjusting the number of threads of the area server to be adjusted for processing the type of operation request according to the adjustment information.
It is understood that, in the present implementation manner, for each type of operation request, a preset time period, load limitation information, performance limitation information, load tolerance information, performance tolerance information, and a preset step corresponding to the type of operation request may be preset. For each type of operation request, the execution main body may adjust the thread processing the type of operation request in an adjustment manner similar to various implementations in the embodiment, so as to individually and flexibly adjust the thread processing various types of operation requests.
With continuing reference to FIG. 4, an exemplary flow 400 of one embodiment of a method for dynamically adjusting zone server threads in accordance with the present application is shown and includes the steps of:
step 401, collecting operation information of the server in the area to be adjusted based on a preset time interval.
Step 402, taking the average value of the operation information collected in the preset time period from the current time as the operation information of the server in the area to be adjusted in the preset time period.
Step 403, in response to determining that the machine utilization rate represented by the load information is less than the machine utilization rate represented by the load limitation information, the request processing time represented by the performance information is less than the request processing time represented by the performance limitation information, the difference between the machine utilization rate represented by the load limitation information and the machine utilization rate represented by the load information is greater than the machine utilization rate represented by the load tolerance information, and the difference between the request processing time represented by the performance limitation information and the request processing time represented by the performance information is greater than the request processing time represented by the performance tolerance information, determining adjustment information for performing capacity expansion of a preset step size on the thread of the area server to be adjusted.
Step 404, in response to determining that the machine utilization represented by the load information is not less than the machine utilization represented by the load limiting information, or that the request processing time represented by the performance information is not less than the request processing time represented by the performance limiting information, determining adjustment information for performing capacity reduction on the thread of the area server to be adjusted.
Step 405, in response to determining that the machine usage rate represented by the load information is less than the machine usage rate represented by the load limitation information, and the request processing time represented by the performance information is not less than the request processing time represented by the performance limitation information, and the difference between the machine usage rate represented by the load limitation information and the machine usage rate represented by the load information is not greater than the machine usage rate represented by the load tolerance information, or the difference between the request processing time represented by the performance limitation information and the request processing time represented by the performance information is not greater than the request processing time represented by the performance tolerance information, expanding the capacity of the thread of the area server to be adjusted, and processing the received operation request by the thread currently running in the area server to be adjusted.
As can be seen from this embodiment, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for dynamically adjusting a thread of a zone server in this embodiment specifically illustrates an adjustment process of a thread of a zone server to be adjusted, so that flexibility and accuracy of adjusting the processing capability of the zone server are further improved.
