[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Looking back at past railway transportation incidents, the problem of verbal friction between passengers has become increasingly serious, especially during the Spring Festival travel season and holidays, most of which are caused by seat issues. At present, the railway seat selection system can support seat selection and can support consecutive seats if multiple people select seats. If there is no middle seat or no seat is selected, the seat selection system will automatically randomly assign consecutive seats (for example, it can randomly assign consecutive seats AB, BC, CD or DF, etc.). When the amount of seat selection data during holidays increases dramatically, the automatic random assignment of consecutive seats is still not perfect.

[0059] In view of the above problems, an embodiment of the present invention provides a sharded railway seat selection method, which can reduce many inconveniences among passengers. Specifically, in the method of the embodiment of the present invention, a seat change application function is added to the railway seat selection system. In this way, passengers can determine whether they need to change seats after determining seats. In the railway seat selection system, the priority of the transaction of the number of travelers can be increased. Then, the priority of the seat change application request proposed based on the seat change application function will be increased accordingly, ensuring that high-priority transactions can be processed first, thereby avoiding a database overload of the railway seat selection system caused by a sudden increase in data volume and causing system errors. Solving the load problem of the railway seat selection system also solves the problem of poor seat selection experience for some passengers caused by seat selection.

[0060] Reference Figure 1 , shows a flow chart of the steps of a railway seat selection method provided in an embodiment of the present invention, which is applied to a railway seat selection system. The method may specifically include the following steps:

[0061] Step 101: Provide the passenger with a seat change option.

[0062] Step 102: Receive seat change intention information submitted by the passenger for the seat change intention option.

[0063] In an embodiment of the present invention, the railway seat selection system is a sharded railway seat selection system. Exemplarily, the sharded railway seat selection system can be a sharded railway seat selection system based on Vitess. Vitess is a horizontal expansion system for MySQL. Vitess supports automatic sharding, and data can be distributed on multiple database instances to achieve horizontal expansion. Sharding is to flexibly design sharding strategies according to business needs and data characteristics. Of course, in actual applications, in addition to the sharded railway seat selection system based on Vitess, there may also be other sharded railway seat selection systems, such as sharded railway seat selection systems based on MongoDB, Apache Cassandra, and Elasticsearch, etc., and the embodiment of the present invention does not need to be limited to this.

[0064] In an embodiment of the present invention, a radio button or drop-down menu style seat change willingness option is added to the railway seat selection system to allow passengers to choose whether they are willing to change seats. Figure 2, is a schematic diagram of an application environment provided in an embodiment of the present invention. The railway seat selection system can be connected to a terminal device such as a passenger's mobile phone for communication. When the passenger selects a seat, locks a seat, pays for a ticket, etc. through the terminal device, the passenger can receive a seat change intention option provided by the railway seat selection system. The passenger selects the option of "willing" or "unwilling" according to his or her actual situation. The corresponding seat change intention information is generated according to the passenger's selection and submitted to the railway seat selection system. The railway seat selection system records the passenger's selection (which can be recorded using a unique identifier) ​​for reference retrieval when processing a seat change application request later.

[0065] Step 103: When the seat change intention information of the passenger indicates that the passenger is willing to change seats, if the companion information submitted by the passenger is received, a confirmation request is sent to the corresponding companion according to the companion information to inquire whether the passenger agrees to change seats.

[0066] Step 104: Receive feedback information from the peer regarding the confirmation request.

[0067] In a specific implementation, a passenger may not be traveling alone, but may be traveling with one or more companions. When the passenger's seat change willingness information indicates that he is willing to change seats, a seat change identity verification is required. Specifically, the passenger is required to provide the companion information of the companions (such as the order number). The railway seat selection system can find the corresponding companions according to the order number and send a confirmation request to the passenger's companions, wherein the confirmation request can be sent through SMS, email, or in-application notification. After receiving the confirmation request, the companions can confirm by clicking on the confirmation link or in the railway seat selection system. After receiving the feedback information submitted by the companions for the confirmation request, if the feedback information is that the passenger agrees to change seats, it can be marked as the seat change identity verification passed. After the seat change identity verification is passed, the railway seat selection system allows the seat change operation based on the passenger's seat.

[0068] In one embodiment of the present invention, the method may further include:

[0069] When the passenger disagrees with the seat change application request, a seat change failure prompt message is sent to the other passengers.

[0070] Of course, when the passenger's willingness to change seats indicates that he is unwilling to change seats, or the feedback information submitted by the companions in response to the confirmation request indicates that they do not agree with the passenger's seat change, the railway seat selection system will not allow seat changes based on the passenger's seat. This can avoid the subsequent forced seat change that may cause passenger dissatisfaction.

[0071] Step 105: When the feedback information indicates that the passenger is allowed to change seats, if the available seats in the current train cannot meet the seat selection requests submitted by other passengers, a seat change application request is submitted to the passenger who is willing to change seats.

[0072] Step 106: When the passenger agrees to change the seat in response to the seat change application, the seat is changed according to the passenger's seat and the available seats on the train.

[0073] In an embodiment of the present invention, other passengers can choose whether they are willing to change seats based on their willingness to change seats, and can also submit the number of seats they need in their own orders. For example, the number of seats they need can be 2. At this time, the railway seat selection system can retrieve the current seat allocation in the database to check whether there are enough consecutive seats to meet the number of seats required by other passengers. If there is a continuous number of seats that meet the requirements, these seats are directly locked and the seat reservation is completed. If there is no continuous number of seats that meet the requirements, the railway seat selection system first locks a single vacant seat to prevent other passengers from having no seats. Then the railway seat selection system retrieves passengers who are willing to change seats, and selects seats from these passengers that meet the number of seats and positions of other passengers (for example, next to the vacant seats). Then, the railway seat selection system sends a seat change application request to these passengers. When the seat change application request is agreed by these passengers, the railway seat selection system can modify the seat information of the passenger and other passengers, regenerate a new order, and notify the passenger and other passengers.

[0074] Of course, if all seat change requests of other passengers are rejected by the passenger, the railway seat selection system can prompt other passengers who cannot change seats and suggest other passengers to choose other seats or other flights.

[0075] In an embodiment of the present invention, a seat change willingness option is provided to passengers, and seat change willingness information submitted by passengers for the seat change willingness option is received. When the seat change willingness information of the passenger is willing to change seats, if the information of the companions submitted by the passenger is received, a confirmation request is sent to the corresponding companions according to the companion information to determine whether to agree to the passenger's seat change, and feedback information of the companions for the confirmation request is received; when the feedback information is to agree to the passenger's seat change, if the vacant seats of the current train cannot meet the seat selection requests submitted by other passengers, a seat change application request is submitted to the passenger who is willing to change seats, and when the passenger agrees to change seats for the seat change application request, the seat change is performed according to the passenger's seat and the vacant seats of the train. In the embodiment of the present invention, after the passenger and the passenger's companions have both determined that they are willing to change seats, the passenger who has a seat change demand can be changed according to the passenger's seat and the vacant seats of the train, which not only avoids disputes and frictions caused by seat selection issues between passengers and their companions, but also comprehensively improves passenger satisfaction and train operation efficiency, and provides a more high-quality and personalized service experience for train passengers.

[0076] In one embodiment of the present invention, the railway seat selection system includes a plurality of databases, each of which stores train information of trains in the railway. Before providing the passenger with a seat change intention option, the method further includes:

[0077] Acquire train information of a train on a railway; wherein the train information includes at least a train identification, a train number, and a train remaining number of seats;

[0078] Extracting target train information from the train information, and determining a shard key based on the target train information;

[0079] The train information is stored in the database respectively according to the sharding key.

[0080] In an embodiment of the present invention, a railway seat selection system includes multiple databases. The railway seat selection system can obtain train information of all trains in the railway, wherein the train information can at least include information such as train identification, number of trains, and number of remaining seats on the train. The target train information is further extracted from the train information. Exemplarily, the target train information can be the number of trains and the number of remaining seats on the train. Then, a shard key can be designed based on the number of trains and the number of remaining seats on the train or other factors, and the train information can be stored in different databases based on the shard key to balance the load and avoid overloading a single database node. Specifically, the shard key is a key field that determines the distribution of data (such as train information) between different shards (databases), which directly affects the load balancing of the data and the efficiency of data query.

[0081] In one embodiment of the present invention, the method may further include:

[0082] receiving an event request submitted by the passenger;

[0083] Determine the priority corresponding to the event request; wherein the priorities respectively have corresponding message queues;

[0084] Putting the event request into the corresponding message queue according to the priority corresponding to the event request;

[0085] The event request in the message queue is processed according to the priority corresponding to the message queue.

[0086] In an embodiment of the present invention, the railway seat selection system defines priority rules. In a specific example of the present invention, event requests submitted by passengers can be prioritized as follows: High-priority event requests (high-priority transactions): event requests (operations) for passenger seat selection and seat locking. These event requests are crucial to the passenger's seat selection experience and require immediate response. Medium-priority event requests (medium-priority transactions): payment and order confirmation. Although these event requests are also important, they can tolerate slight delays. Low-priority event requests (low-priority transactions): train seat map updates, train number updates, etc. These event requests usually do not need to be completed immediately and can be processed when the railway seat selection system load is low.

[0087] Specifically, different message queues are set in the database connection pool. Different message queues have different priorities. Event requests are placed in message queues of corresponding priorities according to their priorities. Then, the railway seat selection system can process event requests in the message queues in order according to their priorities, thereby ensuring that high-priority transactions are processed first.

[0088] In one embodiment of the present invention, the receiving the event request submitted by the passenger includes:

[0089] The event request submitted by the passenger is received according to the preset flow limiting rules.

[0090] In an embodiment of the present invention, the railway seat selection system can process and receive event requests submitted by passengers according to pre-set current limiting rules. Specifically, the current limiting rules limit the upper limit of the number of event requests that the railway seat selection system can process within a certain time window. When the request arrives at the railway seat selection system, the railway seat selection system will check whether the number of requests in the current time window has reached or exceeded the preset limit. If it does not exceed the preset limit, the event request can be received and processed. If it exceeds the preset limit, additional event requests will be rejected or delayed. Of course, in order to ensure that high-priority event requests can be processed normally, the current limiting rules can also be set to receive and process high-priority event requests normally even if they exceed the preset limit, thereby ensuring the passenger's seat selection experience.

[0091] In an embodiment of the present invention, after processing the event request in the message queue according to the priority corresponding to the message queue, the method further includes:

[0092] When the event request is a target event request, cache data corresponding to the event request is searched in the cache of the railway seat selection system. If cache data corresponding to the event request exists in the cache of the railway seat selection system, the cache data is fed back to the passenger. If cache data corresponding to the event request does not exist in the cache of the railway seat selection system, after obtaining the corresponding data from the database of the railway seat selection system, the data is cached in the cache of the railway seat selection system as cache data within a preset cache time.

[0093] In an embodiment of the present invention, for an event request for a target event request, the railway seat selection system can set a cache setTime function for its corresponding data. Specifically, the setTime function refers to setting an expiration time or validity period for the cached data. The setTime function can be used to control the life cycle of the cached data, ensuring that the cached data automatically expires or is removed after a certain period of time, thereby maintaining the freshness and consistency of the data. Among them, the target event request can be an event request for requesting a train seat map update, a train number update, etc. for data that is frequently read from the database. For these event requests, the cache can be used to reduce direct access to the back-end database, thereby reducing the load on the railway seat selection system.

[0094] Specifically, when the event request is a target event request, such as an event request for updating a train seat map, it is possible to search in the cache of the railway seat selection system whether there is cache data corresponding to the event request. If there is cache data corresponding to the event request in the cache of the railway seat selection system, the cache data will be directly fed back to the passenger from the cache. If there is no cache data corresponding to the event request in the cache of the railway seat selection system, the corresponding data can be obtained from the database of the railway seat selection system and cached in the cache of the railway seat selection system as cache data within a preset cache time. In this way, when the target event request is received again subsequently, there is no need to access the database of the railway seat selection system, but only the cache of the railway seat selection system can be accessed.

[0095] In an embodiment of the present invention, after processing the event request in the message queue according to the priority corresponding to the message queue, the method further includes:

[0096] Taking the database of the railway seat selection system that needs to be accessed by the event request as the target database;

[0097] Sending a prepare request to the target database;

[0098] Upon receiving a ready instruction returned by the target database in response to the prepare request, locking the target database and submitting the event request to the target database;

[0099] When all the processing results of the target databases for the event request are obtained, the processing results are fed back to the passenger and the target database is released;

[0100] When the processing results of the event request fed back by all the target databases are not obtained, the target database is released.

[0101] In the specific implementation, after receiving the event request submitted by the passenger, if the event request only requires one shard (database), the event request can be directly submitted to the database and processed. If the event request requires multiple databases, that is, the event request is a cross-shard transaction, the railway seat selection system provides a two-phase commit protocol to ensure ACID (atomicity, consistency, isolation, and durability) properties, while minimizing the time of locking the resources of the railway seat selection system (such as database). Among them, ACID properties are a set of standards in database transaction processing, which are used to ensure the reliability and consistency of transactions.

[0102] Specifically, the processing of event requests by the railway seat selection system can be divided into two stages, namely the preparation stage and the submission stage. In the preparation stage, the transaction manager of the railway seat selection system sends a preparation request to the database, returns a ready instruction if successful and locks the target database that needs to participate in the event request processing, and returns a termination instruction if failed; in the submission stage, after receiving the ready instruction, the event request is submitted to the database so that the database processes the transaction corresponding to the event request. When all target databases feedback the processing results of the event request, the processing results can be fed back to the passengers and the target database is released. Of course, if all target databases do not feedback the processing results of the event request, the target database is released and a termination instruction is received. At this time, the transaction manager is required to roll back the data and release the target database to avoid the railway seat selection system being in an occupied state.

[0103] In one embodiment of the present invention, the method further comprises:

[0104] Receiving an active seat change application request sent by a seat change passenger; the active seat change application request is generated by the seat change passenger inputting train order information of the seat change passenger;

[0105] If the seat-changing passenger receives consent information for the active seat-changing application request, the seats of the seat-changing passenger and the seat-changing passenger are changed.

[0106] In an embodiment of the present invention, when passengers select seats in a railway seat selection system, when two passengers (i.e., the seat-changing passenger and the seat-changed passenger) wish to change seats, but the two passengers are not booked in the same order, that is, the two passengers have reserved seats in different orders, for example, passenger A has reserved seat A1 in order 1, and passenger B has reserved seat B2 in order 2, at this time, passenger A and passenger B can negotiate and decide who will initiate an active seat change application request, and then, the seat-changing passenger (e.g., passenger A) who initiates the active seat change application request needs to input the order number of the seat-changed passenger (e.g., passenger B) in the railway seat selection system. After receiving the active seat change application request from passenger A, the railway seat selection system will send a confirmation request to passenger B, asking passenger B whether he agrees to the seat change. If the consent information of passenger B to the active seat change application request is received, the seats of the seat-changing passenger and the seat-changed passenger can be changed.

[0107] In one embodiment of the present invention, the method further comprises:

[0108] After receiving the active seat change application request sent by the seat-changing passenger, the passenger whose seat is changed and the seat-changing passenger are prohibited from sending new active seat change application requests.

[0109] In an embodiment of the present invention, after the seat-changing passenger sends an active seat-changing application request, the railway seat selection system will temporarily lock the seat-changing passenger and the passenger whose seat is changed. At this time, neither the seat-changing passenger nor the passenger whose seat is changed can initiate new active seat-changing application requests, thereby avoiding malicious seat changes (i.e. malicious passengers (or malicious third parties) constantly initiate active seat-changing application requests to interfere with others) and resource waste (i.e. system resources are occupied by unnecessary seat-changing requests), which interferes with the normal seat-changing process.

[0110] In order to enable those skilled in the art to better understand the embodiments of the present invention, a specific example is used below for illustration. Figure 3 , is a schematic diagram of a process of selecting and changing seats on a railway provided in an embodiment of the present invention. The specific process of selecting and changing seats is as follows:

[0111] When passengers select their seats:

[0112] 1. When passenger A selects his seat: Select seat: Seat 12A; and select whether he is willing to change seats: Yes / No / Ask.

[0113] 2. Passenger A's companion, i.e. Passenger B, receives the confirmation request: Passenger B confirms Passenger A's seat change request through the railway seat selection system (e.g., clicks a confirmation link).

[0114] 3. The railway seat selection system records the seat change request: The railway seat selection system marks the seat change request as approved by the identity review.

[0115] 4. Seat change request processing: The railway seat selection system performs seat change operations based on the selections of passengers A and B.

[0116] When passengers change seats:

[0117] 1. Based on the vitess seat selection system (railway seat selection system);

[0118] 2. Prevent overload (the means to prevent overload may include but are not limited to sharding / caching / current limiting / optimization);

[0119] 3. Priority rules: Priority rules are used to set different priorities for different things (event requests), for example, they can be divided into high / medium / low priority matters;

[0120] 4. Event response; that is, upon receiving an event request, the response can be sorted according to priority;

[0121] 5. If the event request is for passenger seat selection, seat change, etc., it can be submitted to the railway seat selection system to change seats based on the seats and vacancies of the passengers willing to change seats.

[0122] The following processing can be achieved by applying the embodiments of the present invention: 1. Analyze hot data; during holidays, the flow of people is large, and multiple people using the railway seat selection system at the same time will cause the system load to be too high, resulting in system crashes. Intelligent routing and sharding strategies can be used to ensure the load balance of the railway seat selection system so that it can operate normally. Due to the large volume of data, a small amount of data can be migrated to a lower shard (database) that stores the railway seat selection system, so that the system can achieve a uniform distribution effect, avoiding overload of certain shards due to a sudden increase in data volume. Through configuration, high-priority read and write operations can be assigned to shards with better performance or lower load. 2. Cross-shard operation data; in the railway seat selection system, since the seats and the number of travelers are placed in different areas, the database administrator defines corresponding parameters between the areas so that the data on the two shards can be associated. 3. Seat change request: Add a parameter (unique identifier) ​​to indicate whether the passenger is willing to change seats. When passengers choose seats, they can add a seat change willingness option to allow passengers to choose whether they are willing to change seats with other passengers after booking their seats. At the same time, in order to resolve malicious seat changes or avoid seat change conflicts, the passenger's companions also need to complete identity verification, thereby ensuring that there will be no friction caused by the companions' lack of knowledge during subsequent seat changes.
