US 2026/0187030 A1 · DATA STORAGE METHOD, MEDIUM, ELECTRONIC DEVICE, AND PROGRAM PRODUCT

Abstract

This specification provides a data storage method, a medium, an electronic device, and a program product. In this method, when processing to-be-written data, a server selects a data storage policy based on a condition of remaining target disk space. If the target disk space is sufficient, the server preferentially writes the data directly into the target disk space, and then uploads the data to an object storage system, to improve efficiency. If the target disk space is insufficient, the server reads a target file into an internal memory, performs a data append write operation in the internal memory, and directly uploads the target file from the internal memory to an object storage system after the data append write operation is completed, to avoid a data write exception due to the insufficient target disk space. Therefore, flexibility and reliability of data storage are improved.

Claims22

Dependent claims

A data storage method, applied to a storage service node, wherein the method comprises:

obtaining to-be-written data and a file identifier corresponding to the to-be-written data, wherein the file identifier is used to represent a target file for storing the to-be-written data;
when remaining space of target disk space allocated on the storage service node is insufficient, obtaining the target file based on the file identifier, and loading the target file into an internal memory of the storage service node;
writing the to-be-written data into the target file in the internal memory, to obtain a first-type written target file, wherein storage space occupied by the first-type written target file is greater than storage space occupied by the target file;
and
uploading the first-type written target file from the internal memory to an object storage system for storage.

2 more elements

A non-transitory computer-readable storage medium, storing computer instructions, which when executed by a storage service node cause the storage service node to:

obtain to-be-written data and a file identifier corresponding to the to-be-written data, wherein the file identifier is used to represent a target file for storing the to-be-written data;
when remaining space of target disk space allocated on the storage service node is insufficient, obtain the target file based on the file identifier, and load the target file into an internal memory of the storage service node;
write the to-be-written data into the target file in the internal memory, to obtain a first-type written target file, wherein storage space occupied by the first-type written target file is greater than storage space occupied by the target file;
and
upload the first-type written target file from the internal memory to an object storage system for storage.

2 more elements

A storage service node, comprising a memory and a processor, wherein the memory stores executable code, and when the processor executes the executable code, the storage service node is caused to:

obtain to-be-written data and a file identifier corresponding to the to-be-written data, wherein the file identifier is used to represent a target file for storing the to-be-written data;
when remaining space of target disk space allocated on the storage service node is insufficient, obtain the target file based on the file identifier, and load the target file into an internal memory of the storage service node;
write the to-be-written data into the target file in the internal memory, to obtain a first-type written target file, wherein storage space occupied by the first-type written target file is greater than storage space occupied by the target file;
and
upload the first-type written target file from the internal memory to an object storage system for storage.
