database basic information, database: 1 is provided with
Order form table: order; table structure: enumerating partial fields
Order number rule:
prefix (BX | PX) + yyMMddHHmmss (12 bits) + three bits behind machine IP + auto-increment sequence (4 bits)
Case (2): BX2109081758561620001
Driver order form: driver _ order _0-driver _ order _255 (order number field is the same as order table)
Table structure: enumerating partial fields
Order number rules: prefix BX | PX) + yyMMddHHmmss (12 bit) + three bits behind machine IP + auto-increment sequence (4 bit)
Case (2): BX2109081758561620001
And (3) a table division strategy: driver _ id% 256-corresponding table number
Order message middleware MQ:
message middleware: rockmq, version: 4.2.0
Scenario of driver conflict ticket query:
obtaining from an order form: direct query by driver ID
Obtaining from a driver order form: firstly, obtaining a table number through driver _ ID% 256, and inquiring through a driver ID;
and (3) query conditions: reservation pick-up time range + driver ID + order status (including status in all services) so that the driver can be obtained whether there is an order in progress for the driver inquiry period.
Examples are: when the driver ID is 8011, the corresponding data table is: driver _ order _ 075.
As shown in fig. 1, the network car booking platform entry user orders, and the platform agent layer assembles an order information request order system, including: the network appointment platform order number, the city, the longitude and latitude of getting on and off the vehicle, the appointed time of using the vehicle, the basic information of the passenger and the like comprise all order public information.
And the order system successfully places the order and returns the order number to the platform agent layer.
The platform agent layer receives the order number returned by the order system and assembles the order information to request the order.
And the dispatching system receives the dispatching request and begins to screen the drivers.
And assembling the driver information of the screened drivers to call an order system to request whether the drivers have conflicting orders.
The order system receives a detection request of the order conflict order and judges whether an order MQ switch is abnormal or not;
if no abnormity exists, the driver order list information is synchronous with the order list, and a conflict order is obtained from the driver order list;
and abnormal, acquiring the conflict order from the order table.
The switch is a degradation switch, and when the MQ is abnormal, the MQ is manually switched to the order table, so that the condition that the conflict order cannot be inquired is prevented.
Receiving conflict order information returned by the order, making order decision,
driver has conflicting orders, the driver is unavailable;
the driver has no conflicting orders and the driver is available to make the binding.
And dispatching the order to call the order system, binding the order by the driver, updating the order into a state to be served, sending an order MQ message to the order message consumption system, writing the order into a driver order information table, and enabling the state of the driver order table to be served.
And (4) starting service of the order, and updating the state of the order corresponding to the driver order list by sending MQ information to the order information consumption system while updating the state of the order in the subsequent order service process.
Driver order form data exit:
the reason for quitting is as follows: because the driver order form is used for dispatching orders to inquire whether a driver has a conflict order, and the order state of the conflict order is a state in service, for the completed or cancelled order, data can be quitted from the driver order form, the lightweight of the driver order form is ensured, and the efficiency of detecting the driver conflict order is improved.
Exit rules: the data that the vehicle-using time for the order reservation is less than the current time by 1 day and the order state is equal to the completed data can be quitted with the cancelled order data through the reserved vehicle-using time + the order state of the order, so that the service is not influenced, and the query efficiency can be ensured.
Examples are: the current time: 2021-09-13
And (3) exit conditions: book _ date <2021-09-12and status is either completed or cancelled.
Data exit frequency: the exit may be performed daily during a low peak of traffic requests, such as zero-point daily, or 1, 2 a.m..
Has the advantages that: by adding the driver order form table, the order information table with the driver as the dimension is used, the table fields are greatly reduced, the fields such as driver ID, order number, order state, order reservation getting-on time and the like are basically only needed, other service fields are not needed as much as the original order form table, the data table becomes light-weight, simultaneously, conflict order information is obtained from the driver order form table, and the request of a dispatching link to the original order form table can be reduced.
The time for writing in the driver order list is after the driver is dispatched, so that a large amount of order writing before the driver is dispatched is reduced, and meanwhile, data quitting is carried out every day to ensure that all orders in the driver order list are in progress, so that the data in the data list is greatly reduced, and the query performance of conflicting orders of the driver is improved.
The driver order table carries out a table dividing strategy according to the driver ID, and with the increase of platform drivers, the data size of a single table can be prevented from being too large, so that the query performance is guaranteed.
The above embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
