Detailed Description
The core of the application is to provide a method for reading and writing data in a web micro-service cluster, which can ensure normal and effective reading and writing operations under multi-point storage and ensure normal operation of the whole service. At the other core of the application, a reading and writing device, an apparatus and a computer readable storage medium for data in a web micro-service cluster are provided, which all have the above technical effects.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for reading and writing data in a web micro-service cluster according to an embodiment of the present application, and referring to fig. 1, the method mainly includes:
s101: defining a corresponding storage area for each storage service;
specifically, the storage service defines a corresponding storage area for each storage service, and each storage service is responsible for writing data into and reading data from the corresponding storage area.
For example, the storage area corresponding to the storage service 1 is the storage area 1, the storage area corresponding to the storage service 2 is the storage area 2, and the storage area corresponding to the storage service 3 is the storage area 3. Thus, the storage service 1 is responsible for writing data into the storage area 1 and reading data from the storage area 1. The storage service 2 is responsible for writing data into the storage area 2 and reading data from the storage area 2. Similarly, the storage service 3 is responsible for writing data into the storage area 3 and reading data from the storage area 3.
S102: when a write request is received, selecting one storage service, sending data to be written to the selected storage service, and writing the data to be written into the corresponding storage area by the selected storage service;
s103: after the selected storage service completes data writing, other storage services are notified to update the corresponding storage areas;
specifically, after the web micro-service terminal receives the request, the handler first analyzes and confirms the type of the received request, that is, analyzes and confirms whether the received request is a write request or a read request. When the web micro-service terminal receives a write request, the processing program randomly selects one storage service from the storage services, sends the data to be written to the selected storage service, and writes the data to be written into the corresponding storage area by the selected storage service. After the selected storage service finishes data writing, the selected storage service feeds back written information to the processing program, and then the processing program informs other storage services to update the respective corresponding storage areas, and the same data is written in the respective corresponding storage areas, so that data synchronization of the storage areas is realized.
For example, after the storage service 1 writes the data a into the corresponding storage area 1, the storage service 1 feeds back the written information to the processing program, and the processing program notifies the storage service 2 and the storage service 3 to update the corresponding storage areas, so that the storage service 2 writes the data a into the corresponding storage area 2, and similarly, the storage service 3 writes the data a into the corresponding storage area 3.
S104: when a read request is received, one of the storage services is selected, and data is read from the corresponding storage area by the selected storage service.
Specifically, when the web microserver terminal receives a read request, the processing program selects one storage service from the storage services, and the selected storage service reads data from the corresponding storage area.
In a specific embodiment, the selecting a storage service when the read request is received, and causing the selected storage service to read data from the corresponding storage area includes:
if all the storage areas are in the process of writing operation, after the storage areas finish the writing operation, selecting a storage service corresponding to the storage area which finishes the writing operation, and enabling the selected storage service to read data from the corresponding storage area; if the write operation is not carried out in each storage area, one storage service is randomly selected, and the selected storage service reads data from the corresponding storage area; and if the partial storage area is not subjected to the write operation and the partial storage area is subjected to the write operation, selecting a storage service corresponding to the storage area which is not subjected to the write operation, and enabling the selected storage service to read data from the corresponding storage area.
Specifically, when the web microserver terminal receives a read request and wants to read data, there may be several cases that each storage area is performing a write operation, each storage area is not performing a write operation, and a part of the storage area is performing a write operation.
When data is to be read, all the storage areas are in write operation, data reading is not carried out temporarily, after the storage areas are in write operation, a storage service corresponding to the storage area in which the write operation is finished is randomly selected, and the data is read from the corresponding storage area by the selected storage service.
For example, when data is to be read, if all of the storage area 1, the storage area 2, and the storage area 3 are performing write operations, data reading is not performed temporarily, and after any one of the storage area 1, the storage area 2, and the storage area 3 completes a write operation, data reading is performed by a storage service corresponding to one of the storage areas in which the write operation is completed. After the storage area 1 completes the write operation, the storage service 1 corresponding to the storage area 1 reads the data from the corresponding storage area 1.
If the data is to be read, the data is not written in each storage area, then a storage service is directly and randomly selected at the moment, and the data is read from the corresponding storage area by the selected storage service.
For example, when data is to be read, if no write operation is performed in any of the storage area 1, the storage area 2, and the storage area 3, at this time, one storage service is directly selected from the storage service 1, the storage service 2, and the storage service 3 at random, and the data is read from the corresponding storage area by the selected storage service. If the storage service 1 is selected, the storage service 1 reads data from its corresponding storage area 1.
If the data is to be read, the partial storage area is not subjected to the write operation, and the partial storage area is subjected to the write operation, then one of the storage services corresponding to the storage area which is not subjected to the write operation is selected to be read.
For example, when data is to be read, the storage area 1 and the storage area 2 are not written, and the storage area 3 is writing, then one storage service is randomly selected from the storage services 1 and 2 at this time, and the data is read from the corresponding storage area by the selected storage service. If the storage service 1 is selected, the storage service 1 reads data from its corresponding storage area 1.
Further, on the basis of the above embodiment, the method further includes: and if the data to be read does not exist in the storage area, feeding back data non-existence information.
Specifically, when the web microserver terminal reads data after receiving a read request, there may be a case where there is no data to be read in each storage area. In this case, when the selected storage service to be subjected to data reading finds that there is no data to be read in the storage area, the storage service further feeds back data absence information to the handler, so that the web microserver terminal further feeds back information about data absence to the terminal that sent the read request.
In summary, the method for reading and writing data in a web microservice cluster provided by the present application includes: defining a corresponding storage area for each storage service; when a write request is received, selecting one storage service, and sending data to be written to the selected storage service so that the selected storage service writes the data to be written into the corresponding storage area; after the selected storage service completes data writing, other storage services are notified to update the corresponding storage areas; when a read request is received, one of the storage services is selected, and data is read from the corresponding storage area by the selected storage service. The read-write method defines a corresponding storage area for each storage service in a data multi-point storage mode, each storage service is responsible for reading and writing the corresponding storage area, and data synchronization is carried out among the storage areas. When writing data, a storage service can be randomly selected for writing. When reading data, a storage service can also be randomly selected for reading. Therefore, the data can be ensured to be normally written and read by other storage services even if the storage service is occupied, and the normal operation of the whole service is ensured by the normal and effective operation of the read-write operation.
