[0032] Embodiment 1

[0033] Figure 1 1 is a flow chart of a session management method provided according to the first embodiment of the present invention. This embodiment is applicable to managing the session between the client and the database. The method can be executed by a session management device. The session management device can be implemented in the form of hardware and / or software. The session management device can be configured in a computing device. Figure 1 As shown, the method includes:

[0034] S110: When receiving a session query request, determine a first object identifier in the session query request.

[0035] The session query request may be a program or code for requesting information related to a specific session. The session refers to an interactive session between a client and a database. Exemplarily, when a connection request is initiated by any client, a session is established, and the session ends until the client disconnects or times out. The first object identifier is an object identifier of a session query object, which is used to identify the uniqueness of the session query object, such as an object ID, a serial number of a device, a database connection, etc. A session query object refers to a party that queries a session. For example, a session query object may be a user who is in a session or a user who manages a session.

[0036] In this embodiment, when the session query party wants to obtain information related to a specific session, it can send a session query request to the system. After receiving the session query request, the session query request can be parsed, the request content can be parsed, and the object identifier of the session query object can be extracted as the first object identifier. The advantage of determining the first object identifier is that it can accurately determine whether the session query object has query authority, thereby ensuring that the corresponding session data that is compatible with the object query authority can be fed back to the session query object.

[0037] In this embodiment, the session query request is based on a preset operation and / or a scheduled task according to a screening condition corresponding to at least one screening dimension; the screening dimension includes at least a session object dimension, a session state dimension, and a session time dimension.

[0038] The preset operation may be an operation actively triggered by a user to initiate a session query request. For example, the preset operation includes but is not limited to obtaining a session list, querying detailed information of a specific session, retrieving sessions related to specific conditions, etc. A scheduled task refers to a task that automatically executes a session query, and the session query task may be executed periodically at a preset time, date, or interval. A filtering dimension refers to a parameter used to refine the filtering of different session data. A session filtering condition may be a filtering requirement set when querying session data. For example, the filtering dimension is a session object dimension, and its corresponding filtering condition may be querying session data of which objects participate. The filtering dimension is a session state dimension, and its corresponding filtering condition may be querying session data under which session states. For example, the session state includes but is not limited to "active", "waiting", "completed", "timed out", or "abnormal", etc., such as querying currently active sessions. The filtering dimension is a session time dimension, and its corresponding filtering condition may be querying session data under which specific time, such as the start time, end time, or duration of a session, such as querying sessions occurring within a specific time period.

[0039] Specifically, a specific session query request can be generated by selecting a preset operation and combining the filtering conditions of one or more filtering dimensions; or a timed task can be set to periodically generate a specific session query request based on the filtering conditions corresponding to at least one filtering dimension. In this way, the system can search the database according to the received session query request and return the session data that meets the requirements. For example, see Figure 2 The first object identifier belongs to an object, and the client can input the screening condition and issue a query statement, that is, issue a session query request to the distributed database.

[0040] The technical solution provided in this embodiment supports users to set filtering conditions corresponding to multiple filtering dimensions to filter session data periodically or in real time, which can ensure the real-time and accuracy of query session data while meeting user query needs.

[0041] S120: When the first object identifier satisfies a preset query condition, based on the preset query condition satisfied by the first node and the session query request, obtain the session data to be used.

[0042] Among them, the preset query condition may refer to a condition for determining whether the object of the query session has the permission to query related session data, and which query permissions it has. The first node may be a processing node inside the database management system, used to process the session query request. The first node includes a first data storage node and / or a first computing node. The first data storage node is used to store session-related data, for example. These data may include session object information, session status, session time, etc. The session data to be used may refer to the session data queried according to the session query request. The first computing node is used to process the session query request, forward the session query request or the processed session query request, and for the session data queried according to the session query request.

[0043] In this embodiment, preset query conditions may be preconfigured. Optionally, the preset query condition may be that the object identifier exists in a preset identifier library. The preset identifier library includes object identifiers corresponding to objects with different query permissions, and query permission information associated with the object identifiers. When it is determined that there is an object identifier consistent with the first object identifier in the preset identifier library, it is considered that the first object identifier satisfies the preset query condition. Furthermore, the first node may be used to query the session query object for the to-be-used session data that satisfies its permissions from the first data storage node in combination with the satisfied preset query condition and the session query request.

[0044] It should be noted that the session data that can be queried by different query objects may be different. In order to ensure the accuracy of the session data query and the adaptability to the query object permissions, the first node can obtain the session data to be used based on the preset query conditions and the session query request: when the preset query conditions met are the management object query conditions, the session data to be used corresponding to the session query request is obtained based on the first node; when the preset query conditions met are the managed object query conditions, the session data to be used corresponding to the first object identifier is obtained based on the first node according to the session query request.

[0045] The management object query condition may be a condition for determining whether the object of the query session is the object of the management session, and what query permissions the object has. The managed object query condition may be a condition for determining whether the object of the query session is the object of the managed session, and what query permissions the object has. The query permission priority of the management session object is higher than the query permission priority of the managed session object, that is, the management session object can query the session data of the managed session object, and the managed session object cannot query the session data of the management session object.

[0046] In this embodiment, when the preset query condition satisfied is a management object query condition, the session query object is considered to be a management session object, and the first node can obtain the to-be-used session data corresponding to the session query request, that is, the obtained to-be-used session data is the session data that satisfies all the screening conditions in the session query request. When the preset query condition satisfied is a managed object query condition, the session query object is considered to be a managed session object, and the first node can obtain the to-be-used session data associated with the first object identifier according to the session query request. That is, the to-be-used session data at this time is the session data associated with the first object identifier that satisfies some of the screening conditions in the session query request.

[0047] The technical solution provided by the embodiment of the present invention can manage session query permissions according to the configured object identifier, allowing the management session object to view session data under specific permissions, while the managed session object can only view its own session data, thereby realizing refined query permission control over session data and ensuring the security and management convenience of session data.

[0048] It should be noted that in order to avoid providing session data of specific objects to session query objects, and to avoid management session objects initiating termination instructions for sessions between databases, preset database sessions and preset object sessions can be blocked by default, thereby improving the flexibility and security of session data management and ensuring the stability of database operation.

[0049] In this embodiment, before the first node obtains the session data to be used based on the preset query conditions satisfied and the session query request, the database to be queried can be determined based on the session query request, so as to determine the first node and the second node based on the database to be queried and the data storage type of the database to be queried.

[0050] The database to be queried refers to the database where the session data is stored. The data storage types include multi-shard type and single-shard type. The multi-shard type means that the data of the database is stored in multiple database instances. Each instance is responsible for storing a specific range or a specific type of data. The single-shard type means that the data in the database is stored in a single database instance, and all the data is stored in one instance.

[0051] Specifically, the session query request can be parsed to determine the database where the relevant session data in the query session query request is located, and the database is the database to be queried. Further, the database to be queried and the data storage type of the database to be queried can be combined to determine which node in the first node is responsible for querying the data and which node is responsible for storing the data, and which node in the second node is responsible for querying the data and which node is responsible for storing the data. This is to facilitate processing the session query request based on the first node and the second node, obtain the session data to be used, and achieve accuracy and efficiency in processing and responding to the session query request.

[0052] In this embodiment, based on the first node according to the preset query conditions and the session query request that are satisfied, the session data to be used is obtained, including: if the data storage type is a multi-shard type, based on the first computing node according to the preset query conditions and the session query request that are satisfied, the session data to be processed is obtained from each database to be queried, and the session data to be processed is integrated to obtain the session data to be used; if the data storage type is a single-shard type, the session query request is sent to the first data storage node based on the first computing node; based on the first data storage node according to the preset query conditions and the session query request that are satisfied, the session data to be used is obtained and fed back to the first computing node, so that the first computing node sends the received session data to be used to the client of the object to which the first object identifier belongs.

[0053] In practical applications, when the data storage type is a multi-shard type, the first computing node connected to the client to which the first object identifier belongs can obtain the corresponding session data to be processed from each database to be queried according to the preset query conditions and the session query request that are satisfied. It should be noted that when the first computing node queries data from different databases to be queried respectively, the session query request can be processed so that the processed session query request is compatible with the query specification of the corresponding database to be queried, thereby improving the query efficiency. Furthermore, the obtained session data to be processed can be integrated to form complete session data to be used. When the data storage type is a single-shard type, the first computing node connected to the client to which the first object identifier belongs sends the session query request to the first data storage node where the database to be queried is located. Further, when the first data storage node receives the session query request, it can obtain the session data to be used according to the preset query conditions and the session query request that are satisfied. The first data storage node feeds back the session data to be used to the first computing node, so that the first computing node sends the received session data to be used to the client of the object to which the first object identifier belongs. The technical solution provided by the embodiment of the present invention can improve query efficiency and response speed, while ensuring the accuracy of query session data, by determining which node to process session query requests to obtain session data to be used according to different data storage types.

[0054] S130: Send the session data to be used to the client of the object to which the first object identifier belongs, so that the client generates a session termination instruction and feeds back when determining that a preset termination condition is satisfied based on the session data to be used.

[0055] The preset termination condition may refer to a condition for determining whether to terminate a session. The client of the object to which the first object identifier belongs refers to a client that receives the session data to be used, for example, the client may be a user device, an application, or a server program. The session termination instruction may be a command or request for instructing to terminate a session.

[0056] In this embodiment, the session data to be used may be sent to the client of the object to which the first object identifier belongs, so that the client can process and analyze the session data to be used to determine whether a preset termination condition is met. Optionally, the preset termination condition may be when the idle time reaches a preset idle threshold, when the system resources reach an upper limit, when an error or abnormality occurs during the session, user operation, or other business logic. If it is determined based on the session data to be used that the preset termination condition is met, the client generates a session termination instruction and feeds it back to the system node, so that the system node executes a corresponding operation according to the session termination instruction to terminate the corresponding session, thereby improving the efficiency of session management.

[0057] For example, see Figure 2 After the client sends a session query request, the first node in the distributed database returns the session data to be used to the client. The client can aggregate and display the session data to be used and determine whether to send a session termination instruction. The timing relationship can be seen in Figure 3 .

[0058] S140: When the preset query condition satisfied is a management object query condition and a session termination instruction sent by the client is received, releasing a target session in the session termination instruction based on the second node according to the session termination instruction.

[0059] Among them, the second node includes a second data storage node and / or a second computing node. The target session is a session between the client corresponding to the queried object and the second data storage node. The second computing node can be a node connected to the client of the object to which the first object identifier belongs. The second data storage node can be a node connected to the client of the queried object. It should be noted that the concepts of "first node" and "second node" are relative, not absolute. For example, for a certain session management, node A among many nodes is the first node, and node B is the second node; but for the next session management, node B may be the first node and node A may be the second node, or both node A and node B may be the first node, or both may be the second node.

[0060] In this embodiment, when the preset query condition met is a management object query condition and a session termination instruction sent by the client is received, the second node may perform an operation of releasing the target session in the session termination instruction based on the session termination instruction. For example, the operation of releasing the target session may be clearing the session state (such as clearing all internal states and caches related to the session), releasing resources (releasing resources related to the session, such as memory, file handles, database connections, etc.), updating database records (marking the session as terminated or deleting the session record in the database), etc. Furthermore, the second node may also send a prompt message of successful session release to the client when releasing the target session in the session termination instruction, indicating that the session has been successfully terminated, so that the session query object is informed of the session termination. For example, see further. Figure 2 ,After the client sends the session termination instruction, the node terminates the target ,session and feeds back the prompt information to the client.

[0061] In this embodiment, releasing the target session in the session termination instruction based on the second node according to the session termination instruction includes: if the data storage type is a single-shard type, releasing the target session in the session termination instruction based on the second computing node; if the data storage type is a multi-shard type, sending the session termination instruction to the second data storage node corresponding to the database to be queried based on the second computing node, so that the second data storage node releases the target session in the session termination instruction according to the session termination instruction.

[0062] Specifically, when the data storage type is a single-shard type, the second computing node connected to the client to which the first object identifier belongs can be directly based on the session termination instruction to execute the operation of releasing the target session in the session termination instruction. If the data storage type is a multi-shard type, the session termination instruction can be sent to the second data storage node corresponding to the database to be queried based on the second computing node, so that each second data storage node executes the operation of releasing the target session in the session termination instruction according to the session termination instruction.

[0063] The technical solution provided in the embodiment of the present invention can ensure that the session can be correctly and safely terminated according to the client's request by determining which node to release the target session in the session termination instruction according to different data storage types. At the same time, it also improves data processing efficiency and response speed, and improves the flexibility and convenience of the system in processing session management tasks under different storage architectures.

[0064] The technical solution provided by the embodiment of the present disclosure determines the first object identifier in the session query request when receiving the session query request; when the first object identifier satisfies the preset query condition, based on the first node, obtains the session data to be used according to the preset query condition and the session query request; sends the session data to be used to the client of the object to which the first object identifier belongs, so that when the client determines that the preset termination condition is satisfied based on the session data to be used, it generates a session termination instruction and feedbacks; when the preset query condition satisfied is the management object query condition and the session termination instruction sent by the client is received, based on the second node, the target session in the session termination instruction is released according to the session termination instruction, which solves the problem that the existing technology only supports session management based on its own data, resulting in the inability to meet the needs of different users to manage session data and the poor session management effect. Different nodes can be used to query the corresponding session data for the session query objects that meet different preset query conditions, meet the session management needs, ensure the security of the session data, and improve the query efficiency. At the same time, it supports specific objects to manage target sessions on demand, and improves the flexibility and convenience of session management.
