generating the first index update command such that the first index update command includes the ID information of the other users and the ID information of the first content;

sequentially reading the one or more preceding index update commands and the first index update command;

processing the one or more preceding index update commands and the first index update command,

the processing of the first index update command including adding the ID information of the first content to the indices of each of the other users, based on the first index update command, each of the indices of the other users being stored in an index storage unit, the other users including a second user;

receiving a news feed provision request from the second user;

reading content stored in the content storage unit based on ID information of content included in an index of the second user, the read content including the first content, the ID information of the content included in an index of the second user including the ID information of the first content; and

providing a news feed including the first content to the second user.

2. The method of claim 1 ,

wherein the enqueueing of the first index update command comprises:

in response to a number of the other users having the first relationship with the first user being higher than a pre-set number of unit subscribers, splitting the first index update command into a plurality of index update commands and storing the plurality of index update commands in the queue, and

wherein the processing of the first index update command further includes:

in response to the number of the other users having the first relationship with the first user being higher than the pre-set number of unit subscribers, and the first index update command being split into the plurality of index update commands, adding the ID information of the content to the index of each of the other users stored in the index storage unit, according to the plurality of index update commands stored in the queue.

3. The method of claim 1 , wherein the first index update command further includes the ID information of the first user.

4. The method of claim 1 , further comprising:

adding the ID information of the first content to an index of the first user after the generating ID information of the first content and the storing the first content and the ID information of the first content,

the index of the first user being stored in the index storage unit.

5. The method of claim 1 , wherein the other users having the first relationship with the first user are users subscribed to a channel including content uploaded by the first user.

6. The method of claim 1 , further comprising:

matching a plurality of pieces of content and a plurality of pieces of ID information in a one-to-one manner; and

storing the matched plurality of pieces of content and plurality of pieces of ID information in the content storage unit in the one-to-one manner.

7. The method of claim 1 further comprising:

storing indices of each of users subscribed to the content sharing service, respectively, in the index storage unit,

ID information of content registered by other users being listed in the indices of users from among the users subscribed to the content sharing service.

8. The method of claim 7 , wherein for a first index stored in the index storage unit, ID information stored in the first index is listed in an order corresponding to an order in which content which the ID information stored in the first index identifies was registered.

9. The method of claim 1 , wherein the news feed is a screen in which first content is listed in an order, with respect to other content, that corresponds to an order, with respect to ID information of the other content, in which the ID information of the first content is stored in the index of the second user.

10. A non-transitory computer-readable recording medium storing computer-executable instructions that, when executed by a processor, cause the processor to perform operations including:

receiving, from a first user, a content registration request including first content;

in response to receiving the content registration request,

generating identification (ID) information of the first content,

storing the first content and the ID information of the first content in a content storage unit,

generating a first index update command for updating an index of each of other users having a first relationship with the first user by using the ID information of the first content, and

enqueueing the first index update command in a queue that includes one or more preceding index update commands,

the generating of the first index update command including,

obtaining a list of ID information of the other users having the first relationship with the first user from a user account storage unit based on ID information of the first user, and

generating the first index update command such that the first index update command includes the ID information of the other users and the ID information of the first content;

sequentially reading the one or more preceding index update commands and the first index update command;

processing the one or more preceding index update commands and the first index update command,

the processing of the first index update command including adding the ID information of the first content to the indices of each of the other users, based on the first index update command, each of the indices of the other users being stored in an index storage unit, the other users including a second user;

receiving a news feed provision request from the second user;

reading content stored in the content storage unit based on ID information of content included in an index of the second user, the read content including the first content, the ID information of the content included in an index of the second user including the ID information of the first content; and

providing a news feed including the first content to the second user.

11. An apparatus for providing a content sharing service, the apparatus comprising:

memory storing computer-executable instructions; and

one or more processors configured to execute the instructions such that the one or more processors are configured to,

receive, from a first user, a content registration request including first content,

in response to receiving the content registration request,

generate identification (ID) information of the first content,

store the first content and the ID information of the first content in a content storage unit,

generate a first index update command for updating an index of each of other users having a first relationship with the first user by using the ID information of the first content, and
