The method of claim 3, wherein determining the destination address of the first data content based on the key of the hash table and the linked list array corresponding to the target file comprises: acquiring a hash function corresponding to the linked list array; and determining the destination address of the first data content based on the hash function and the key of the hash table.
  5. The method of claim 1, wherein storing the second data content and the first data content in the storage nodes of the target linked list based on the preset storage rule comprises: acquiring a first storage node where the second data content is located; and storing the first data content on a second storage node of the target linked list, the second storage node is a next storage node immediately adjacent to the first storage node.
  6. The method of any one of claims 1 to 5, wherein after determining the target linked list corresponding to the destination address in the linked list array, and before writing the data content stored in each linked list of the linked list array to the target file in parallel, the method further comprises: in a case where the second data content does not exist in the memory space of the target linked list, storing the first data content in the memory space.
  7. A writing method for a distributed file system applied to a second electronic device, comprising: acquiring a request identification corresponding to the second electronic device and first data content corresponding to the write operation instruction of the user for the target file, in response to a write operation instruction initiated by a user for a target file in a first electronic device, the first electronic device and the second electronic device are communicatively connected to each other; and sending data request information for the target file to the first electronic device, the data request information comprises the request identification and the first data content.

Description

CROSS REFERENCE TO RELATED APPLICATIONS The present disclosure claims the priority to Chinese Patent Application No. 202310975556.1 entitled "WRITING METHOD FOR DISTRIBUTED FILE SYSTEM, AND ELECTRONIC DEVICE" and filed with the CNIPA on August 3, 2023, entire contents of which are incorporated herein by reference. TECHNICAL FIELD Embodiments of the present disclosure relate to the field of terminal technology, and in particular, to a writing method for a distributed file system and an electronic device. BACKGROUND A situation that a plurality of terminals simultaneously accesses a certain file on a same terminal is usually involved in a multi-screen collaboration scenario. For example, there is an office file in a terminal A, and a terminal B and a terminal C need to write data to the file at the same time, which causes a problem of data access conflict. At present, in order to avoid the data access conflict, a system default access interception method is generally adopted, that is, when the terminal B accesses the file, the other terminals A and C are prohibited from accessing the file, but with such method, efficiency of collaborative data writing among the plurality of terminals is not high, and user experience is affected. SUMMARY The embodiments of the present disclosure provide a writing method for a distributed file system and an electronic device, so as to solve a problem of data access conflict in a scenario where a plurality of terminals access a same file collaboratively and improve efficiency of collaborative data writing among the plurality of terminals.
