Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

Referring to FIG. 1, it shows a flowchart of an asynchronous IO data processing method provided by an embodiment of the present application. The asynchronous IO data processing method provided by an embodiment of the present application may include:

S11: Receive an asynchronous IO data storage request; where the asynchronous IO data storage request includes multiple asynchronous IO data fragments.

In a distributed object storage system, when asynchronous IO data needs to be processed, the object gateway receives an asynchronous IO data storage request, where the asynchronous IO data storage request may include multiple asynchronous IO data fragments, and these asynchronous IO data The fragments may not be arranged in the order of the asynchronous IO data, that is, the asynchronous IO data fragments are arranged out of order.

S12: Obtain the tag information of each asynchronous IO data segment, and store the tag information in the pre-created data tag storage pool, and store the asynchronous IO data segment in the data pool; where the tag information may include asynchronous IO data storage The requested object name, the offset of the asynchronous IO data fragment, and the storage location of the asynchronous IO data fragment.

When receiving multiple asynchronous IO data fragments included in the asynchronous IO data storage request, obtain the label information of each asynchronous IO data fragment, and store the label information of these asynchronous IO data fragments in the pre-created data label storage pool At the same time, asynchronous IO data fragments can be stored in the data pool. Among them, the data tag storage pool can be pre-created at the bottom layer of the distributed object storage system to store tag information of asynchronous IO data fragments.

In addition, the tag information mentioned here can specifically include the object name of the asynchronous IO data storage request (specifically, the object name of the asynchronous IO data to be stored included in the asynchronous IO data storage request, and it belongs to the same asynchronous IO data. The data fragments have the same object name), the offset of the asynchronous IO data fragment, and the storage location of the asynchronous IO data fragment, so that the object name of the asynchronous IO data storage request in the tag information can be used to determine the object to which it belongs. The offset of the asynchronous IO data segment in determines the location of the asynchronous IO data segment in the asynchronous IO data, and the storage location of the asynchronous IO data segment determines the location where the asynchronous IO data segment is stored.

It can be seen from the above that it does not reorder the received asynchronous IO data fragments and then store them. Therefore, the time spent on asynchronous IO data storage can be shortened, thereby improving the storage efficiency of asynchronous IO data, and By creating a data tag storage pool to store the tag information of the asynchronous IO data fragments, the integrity and consistency of the asynchronous IO data can be guaranteed, and the performance of the asynchronous IO data storage can be improved.

S13: When receiving the asynchronous IO data reading request, obtain the object name of the asynchronous IO data reading request.

After completing the storage of the asynchronous IO data fragment label information and the asynchronous IO data, if an asynchronous IO data read request is received, the object name of the asynchronous IO data read request can be obtained (specifically in the asynchronous IO data read request) Contains the object name of the asynchronous IO data to be read), so that the asynchronous IO data can be read through the object name of the asynchronous IO data read request.

S14: Obtain all tag information corresponding to the object name of the asynchronous IO data read request in the data tag storage pool, and read according to the offset of the asynchronous IO data segment and the storage location of the asynchronous IO data segment in the tag information The asynchronous IO data corresponding to the asynchronous IO data read request.

When the object name of the asynchronous IO data read request is obtained, all tag information corresponding to the object name of the asynchronous IO data read request can be obtained in the data tag storage pool to ensure that complete asynchronous IO data can be obtained. After that, the asynchronous IO data corresponding to the asynchronous IO data read request can be read according to all the acquired tag information. Specifically, the position of each asynchronous IO data segment in the asynchronous IO data can be determined according to the obtained offset of the asynchronous IO data segment in each tag information, and the position of each asynchronous IO data segment in the asynchronous IO data can be determined according to the asynchronous IO data segment in each tag information. The storage location of the IO data fragment determines the location where the asynchronous IO data fragment is stored, and then reads the asynchronous IO data fragments sequentially and sequentially in the order of the offset of the asynchronous IO data fragment and the storage location of the asynchronous IO data fragment, thereby Improve the efficiency of reading asynchronous IO data.

The above solution disclosed in this application obtains the tag information of each asynchronous IO data segment and stores the tag information in a pre-created data tag storage pool, and when an asynchronous IO data read request is received, the data tag is stored Obtain the tag information corresponding to the object name of the asynchronous IO data read request from the pool, and read the asynchronous IO data according to the offset of the asynchronous IO data fragment in the tag information and the storage location of the asynchronous IO data fragment, so that there is no need to correct or wrong The sequential asynchronous IO data fragments are reordered, so that the processing time of asynchronous IO data can be shortened, and the processing efficiency and processing performance of asynchronous IO data can be improved.

An asynchronous IO data processing method provided by an embodiment of the present application, which obtains label information of each asynchronous IO data fragment, may include:

When an asynchronous IO data storage request is received, the first label information of each asynchronous IO data segment is acquired; where the first label information may include the ID information of the asynchronous IO data storage request, the offset of the asynchronous IO data segment, and the asynchronous The storage location of the IO data fragment;

When the asynchronous IO data storage request ends, the ID information of the asynchronous IO data storage request in the first label information is changed to the object name of the asynchronous IO data storage request to obtain the label information of each asynchronous IO data segment.

Specifically, the label information of each asynchronous IO data fragment can be obtained in the following ways:

Considering that in the initial stage of receiving the asynchronous IO data storage request, the corresponding request ID will be assigned to the asynchronous IO data storage request. Therefore, when the asynchronous IO data storage request is received, the first tag information of each asynchronous IO data segment can be obtained , Where the first tag information includes the ID information of the asynchronous IO data storage request (asynchronous IO data fragments that belong to the same asynchronous IO data have the same request ID information), the offset of the asynchronous IO data fragment, and the storage of the asynchronous IO data fragment When the asynchronous IO data is stored, the request ID information will be released. In order to facilitate the subsequent accurate reading of the asynchronous IO data, when the asynchronous IO data storage request ends, the asynchronous IO in the first tag information can be changed The ID information of the data storage request is changed to the object name of the asynchronous IO data storage request, so that the label information of each asynchronous IO data fragment can be obtained through the object name.
