[0054] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0055] Figure 2 FIG. 1 is a schematic diagram of the main process of the snapshot generation method according to an embodiment of the present invention. Figure 2 As shown, the snapshot generation method of the present invention includes:

[0056] Step S201, receiving a snapshot generation request; the snapshot generation request indicates an item identifier and a task identifier for which a snapshot is to be generated.

[0057] The snapshot is a display photo or display page of the product details page corresponding to the moment when the user places an order; wherein, the order placed by the user may include one or more items, and each item corresponds to a details page.

[0058] In the embodiment of the present invention, before receiving the snapshot generation request, the snapshot data is pre-stored, and the snapshot data may include text, pictures, and the like.

[0059] In the embodiment of the present invention, the task identifier may be orderId, the item identifier may be skuID of one or more items in the order, and the snapshot to be generated is a snapshot corresponding to orderId and skuID.

[0060] Step S202, determining target snapshot data corresponding to the task identifier and the item identifier from the pre-stored snapshot data corresponding to the plurality of historical tasks; the snapshot data is pre-extracted from the transaction data of the plurality of historical tasks and stored corresponding to the historical tasks.

[0061] In the embodiment of the present invention, the historical tasks may be multiple user orders, and the target snapshot data includes snapshot data of the details page corresponding to the task identifier and the item identifier.

[0062] In the embodiment of the present invention, Figure 3 As shown, the snapshot data storage method of the present invention comprises the following steps:

[0063] Step S301: extract snapshot data corresponding to one or more item identifiers from the transaction data in each historical task.

[0064] In an embodiment of the present invention, each snapshot data includes one or more transaction fields, and the transaction fields include any one or more of the following: item specification information, item image information, item price information, item discount information, item fulfillment information, item service information, item delivery information, and item provider information.

[0065] Step S302: determining the reuse rate of the transaction field according to the data storage space required for storing the transaction field and the data update cycle of the transaction field.

[0066] In the embodiment of the present invention, the multiplexing rate of the transaction field is f, the data storage space required to store the transaction field is s, and the data update period of the transaction field is z.

[0067] In the embodiment of the present invention, the relationship between f, s, and z can be: f = s*z. For example, the data storage space f required to store item discount information is 10KB, and the data update cycle of the item discount information is 2 days, then the reuse rate of the item discount information is f = s*z = 10*2 = 20; for another example, the data storage space f required to store item fulfillment information is 0.1KB, and the data update cycle of the item fulfillment information is 0.3 days, then the reuse rate of the item fulfillment information is f = s*z = 0.1*0.3 = 0.03.

[0068] In the embodiment of the present invention, the transaction fields that are updated simultaneously may be combined to calculate the reuse rate.

[0069] Step S303: determining the storage mode corresponding to the transaction field in the snapshot data according to the reuse rate of the transaction field.

[0070] In an embodiment of the present invention, when the reuse rate of the transaction field is not less than the reuse rate threshold, the storage mode of the transaction field is determined to be compressed storage; when the reuse rate of the transaction field is less than the reuse rate threshold, the storage mode of the transaction field is determined to be any storage mode, such as compressed storage or non-compressed storage.

[0071] In the embodiment of the present invention, the multiplexing rate is not less than the multiplexing rate threshold, corresponding to a high multiplexing rate; the multiplexing rate is less than the multiplexing rate threshold, corresponding to a low multiplexing rate.

[0072] In the embodiment of the present invention, the snapshot data includes a task identifier, an item identifier, a transaction field, and a value of the transaction field.

[0073] In the embodiment of the present invention, the snapshot data is stored in the HBASE database according to the corresponding storage method.

[0074] Step S304: compress and store the transaction fields with high reuse rate and the values ​​of the transaction fields in a shared data table of the HBASE database.

[0075] In the embodiment of the present invention, according to the task identifier of the historical task, the item identifier of one or more items corresponding to the historical task, the transaction field corresponding to the item identifier, and the value of the transaction field, storage is performed in accordance with the storage method corresponding to the transaction field. The transaction field with a high reuse rate corresponding to the item identifier and the value of the transaction field are compressed and stored; the transaction field with a low reuse rate corresponding to the task identifier and the item identifier and the value of the transaction field are non-compressed and stored.

[0076] In the embodiment of the present invention, the transaction fields with high reuse rate and the values ​​of the transaction fields are compressed and stored in the shared data table snapshot_shared of the HBASE database.

[0077] In the embodiment of the present invention, after determining the transaction field with high reuse rate and the value of the transaction field, when compressing and storing them in the shared data table snapshot_shared of the HBASE database, it is queried whether snapshot_shared includes the transaction field with high reuse rate. If snapshot_shared includes the transaction field with high reuse rate, it is directly stored according to the value of the transaction field corresponding to the item identification; if snapshot_shared does not include the transaction field with high reuse rate, a transaction field corresponding to the item identification is created, and the value of the corresponding transaction field is saved. Therefore, the shared data table snapshot_shared includes the transaction field with high reuse rate corresponding to the item identification and the value of the transaction field.

[0078] In an embodiment of the present invention, when the transaction fields with high reuse rate and the values ​​of the transaction fields are compressed and stored in the shared data table snapshot_shared of the HBASE database, the item identification and the transaction fields with high reuse rate are used as the rowkey of the shared data table snapshot_shared (for example, ${skuID}-${transaction field}), and the value of the transaction field is used as the corresponding value.

[0079] Step S305, concatenate and encrypt the transaction fields with high reuse rate to determine the sharedkey.

[0080] In the embodiment of the present invention, the transaction fields with high reuse rate are concatenated and encrypted, and used as the value of snapshot_version in the private data table snapshot_private with rowkey as snapshot_version, which is recorded as sharedkey.

[0081] In the embodiment of the present invention, the encryption method may be md5 encryption.

[0082] Step S306, storing the sharedkey and the data with low reuse rate in a private data table.

[0083] In the embodiment of the present invention, the sharedkey and the transaction field with low reuse rate and the value of the transaction field are stored in the private data table snapshot_private of the HBASE database. Therefore, the private data table snapshot_private includes the transaction field with low reuse rate and the value of the transaction field corresponding to the task identifier and the item identifier, snapshot_version and the value of snapshot_version.

[0084] In an embodiment of the present invention, when transaction fields with low and high reuse rates and the values ​​of transaction fields are stored in the private data table snapshot_private of the HBASE database, the task identifier, item identifier and transaction fields with low reuse rates are used as the rowkey of the private data table snapshot_private (for example, ${orderId}-${skuID}-${transaction field}), and the value of the transaction field is used as the corresponding value; snapshot_version is used as the rowkey of the private data table snapshot_private (for example, ${orderId}-${skuID}-${snapshot_version}), and sharedkey is used as the value of snapshot_version.

[0085] In the existing snapshot storage, a snapshot is generated and stored in real time every time an order is received. The number of snapshots generated and stored is equal to the number of products in each order. If an order includes three products, three snapshots will be generated and stored. If a snapshot is stored for each product under an order, when the order volume increases suddenly, the storage of snapshots will occupy a huge amount of storage resources. However, the description information of a product is usually unchanged in a short period of time. Accordingly, snapshots can be reused in a short period of time, especially in similar scenarios such as flash sales. The product snapshots are the same within one minute, but the number of orders may be tens of thousands, resulting in the repeated storage of a large number of snapshots, wasting a lot of storage space.

[0086] Through the snapshot data storage method of the present invention, only the snapshot data of the product is saved. For multiple products of an order, compared with the method of saving multiple snapshots, storage resources can be saved, the consumption of storage space can be reduced, and the waste of storage resources can be prevented; for similar scenarios such as flash sales, the same product only needs to save snapshot data once, which greatly reduces the consumption of storage resources and improves storage efficiency.

[0087] In the embodiment of the present invention, the snapshot data storage method of the present invention can save storage resources, reduce the consumption of storage space, and prevent the waste of storage resources.

[0088] In the embodiment of the present invention, after determining the data in the shared data table and the private data table, the data can be compressed again and stored in the HBASE database. By compressing the data again based on determining different storage methods according to the reuse rate, storage resources can be further saved, the consumption of storage space can be reduced, and the waste of storage resources can be prevented.

[0089] In an embodiment of the present invention, the text of the target snapshot data may be a transaction field and the value of the transaction field, including item specification information and the value of the item specification information; item price information and the value of the item price information; item discount information and the value of the item discount information; item fulfillment information and the value of the item fulfillment information; item service information and the value of the item service information; item delivery information and the value of the item delivery information; item provider information and the value of the item provider information. For example, key is item specification information, value is "12L", "13L", "16L", "17L", etc.; key is item price information, value is "1099", "1599", "2099", "2999", etc.; key is item discount information, value is "gift", "discount on purchase over a certain amount", etc.; key is item fulfillment information, value is "inventory (1653)", "inventory (1825)", "inventory (459)", "inventory (569)", etc.; key is item service information, value is "safe shopping", "warranty period of 1 year", etc.; key is item delivery information, value is "No. xx, building xx, unit xx, xx community, xx road, xx street, Xicheng District, Beijing"; key is item provider information, value is "self-operated", "third party", etc.

[0090] The target snapshot data may be a transaction field and a value of the transaction field, including item image information and the value of the item image information. For example, the key is the item image information, and the value is one or more item images on the detail page.

[0091] In the embodiment of the present invention, the target snapshot data comes from the HBASE database.

[0092] In the embodiment of the present invention, when determining the target snapshot data corresponding to the task identifier and the item identifier from the snapshot data corresponding to the pre-stored multiple historical tasks, the private data table snapshot_private and the shared data table snapshot_shared in the HBASE database are queried.

[0093] like Figure 4 As shown, the query method of target snapshot data of the present invention includes the following steps:

[0094] Step S401, determining private data in a private data table according to the task identifier and the item identifier.

[0095] In the embodiment of the present invention, the private data in the private data table is determined according to orderId and skuID. For example, the rowkey "${orderId}-${skuID}-${transaction field}" of the private data table snapshot_private is queried to determine the low-reuse transaction field corresponding to orderId and skuID in the private data table snapshot_private and the value of the transaction field.

[0096] Step S402, determining the sharedkey in the private data table according to the task identifier and the item identifier.

[0097] In the embodiment of the present invention, according to orderId and skuID, the value corresponding to snapshot_version in the private data table snapshot_private is queried to determine the sharedkey corresponding to skuID. For example, the rowkey "${orderId}-${skuID}-${snapshot_version}" of the private data table snapshot_private is queried to determine the sharedkey corresponding to skuID.

[0098] Step S403, decrypt the sharedkey.

[0099] Step S404, determining the shared data in the shared data table according to the item identification and the decrypted sharedkey.

[0100] In the embodiment of the present invention, skuID and the decrypted sharedkey are concatenated to obtain ${skuID}-${sharedkey}, and the shared data table snapshot_shared is queried, and ${skuID}-${sharedkey} is used as the rowkey to determine the shared data in the shared data table. For example, the rowkey "${skuID}-${transaction field}" of the shared data table snapshot_shared is queried to determine the high-reuse transaction field corresponding to the item identifier and the value of the transaction field.

[0101] In the embodiment of the present invention, the target snapshot data can be quickly acquired through the query method of the target snapshot data of the present invention, so as to be used for generating the target snapshot when a transaction dispute or other needs arise.

[0102] Step S203: Generate a target snapshot corresponding to the item identifier according to the target snapshot data and a preconfigured snapshot generation template.

[0103] In an embodiment of the present invention, the snapshot generation template can be a page template. The page template can be written by using the FreeMarker template engine and the written page template is stored in a relational database (e.g., a MySQL database). When generating a snapshot, the page template is obtained from the MySQL database and the page template is rendered using the target snapshot data to obtain a page including the target snapshot.

[0104] In the embodiment of the present invention, the snapshot generation template may also be a picture template, a document template, etc.

[0105] In the embodiment of the present invention, when the snapshot generation template is stored in the MySQL database, the item identification and the snapshot generation template are stored correspondingly.

[0106] In an embodiment of the present invention, when determining the snapshot generation template, the corresponding snapshot generation template is searched from the MySQL database according to the item identifier; alternatively, the snapshot data in the HBASE database and the snapshot generation template in the MySQL database can be associated according to other identifiers to generate the target snapshot.

[0107] In the embodiment of the present invention, Figure 5 As shown, the method for generating a snapshot generation template of the present invention comprises the following steps:

[0108] Step S501, obtaining a plurality of historical tasks; wherein the historical tasks indicate task identifiers.

[0109] Step S502, determining one or more identical historical items in multiple historical tasks; wherein the historical items indicate item identifiers.

[0110] In the embodiment of the present invention, each historical task includes one or more historical items, wherein the same historical items correspond to the same item identifier.

[0111] Step S503: determining a plurality of historical transaction fields corresponding to the item identifier according to one or more historical items corresponding to the item identifier.

[0112] Step S504, determining a transaction field with a high reuse rate among the multiple historical transaction fields.

[0113] Step S505: determining a snapshot generation template according to the historical transaction fields with high reuse rate.

[0114] Step S506: storing the snapshot generation template in the MySQL database.

[0115] In the embodiment of the present invention, through the snapshot generation template generation method of the present invention, multiple snapshot generation templates can be generated, so as to be used for generating target snapshots when transaction disputes or other needs arise.

[0116] In the embodiment of the present invention, by receiving a snapshot generation request; the snapshot generation request indicates the item ID and the task ID of the snapshot to be generated; determining the target snapshot data corresponding to the task ID and the item ID from the snapshot data corresponding to the pre-stored multiple historical tasks; the snapshot data is pre-extracted from the transaction data of the multiple historical tasks and stored according to the historical tasks; generating the snapshot corresponding to the item ID according to the target snapshot data and the pre-configured snapshot generation template, etc., it is possible to save storage resources, reduce the consumption of storage space, and prevent the waste of storage resources. .

[0117] Figure 6 is a schematic diagram of main modules of a snapshot generating device according to an embodiment of the present invention, such as Figure 6 As shown, the snapshot generating device 600 of the present invention includes:

[0118] The receiving module 601 is used to receive a snapshot generation request; the snapshot generation request indicates the item identifier and task identifier of the snapshot to be generated.

[0119] In the embodiment of the present invention, the receiving module 601 of the snapshot generating device 600 is used to receive a snapshot generating request.

[0121] In an embodiment of the present invention, when the data processing module 602 determines the target snapshot data corresponding to the task identifier and the item identifier from the snapshot data corresponding to multiple pre-stored historical tasks, it queries the private data table snapshot_private and the shared data table snapshot_shared in the HBASE database to determine the target snapshot data corresponding to the task identifier and the item identifier.

[0126] In an embodiment of the present invention, the snapshot generation template can be a page template. The page template can be written by using the FreeMarker template engine, and the written page template is stored in a relational database (for example, a MySQL database). When generating a snapshot, the generation module 603 obtains the page template from the MySQL database, and uses the target snapshot data to render the page template to obtain a page including the target snapshot.
