Description

Technical Field

[0001] The present disclosure relates to the field of data processing, and in particular to a data transmission method, device, equipment and storage medium. Background Art

[0002] In the data transmission of multi-language applications, due to the differences in programming languages, data cannot be transmitted normally between different functional modules developed in different languages. At present, a serialization and deserialization solution is proposed to address the above problems. Among them, serialization and deserialization are relative. Serialization refers to the conversion of the data type of the data object into binary data, and deserialization refers to the conversion of binary data into other data types.

[0003] In an application scenario, take a module A written in the Java programming language calling a module B written in the C++ programming language as an example. Specifically, the Java data object in module A is first serialized into a byte array using a serialization and deserialization tool, and the byte array is sent to module B through network transmission. After module B receives the serialized byte array, it deserializes the byte array into a data type object that module B can recognize, and then obtains the required data type object from the data type object to perform subsequent operations.

[0004] However, the above method requires full serialization of the Java data object to be transmitted. At the same time, after module B receives the serialized byte array, the byte array also needs to be fully deserialized. However, since the transmitted data usually includes redundant data, the above processing method results in low data transmission efficiency between module A and module B. Summary of the invention

[0051] At present, in cross-language applications, how to improve the data transmission efficiency between functional modules developed in different programming languages ​​is a technical problem that needs to be solved.

[0052] To this end, an embodiment of the present disclosure provides a data transmission method, specifically, calling a first function module to generate a target data object based on a preset memory structure, wherein the target data object includes key-value data stored based on the preset memory structure, the preset memory structure includes at least one storage unit, the storage unit includes a key field and a value field, the key field is used to store key data in the key-value data, and the value field is used to store value data corresponding to the key data, and then, the target data object is transmitted to a second function module, wherein the second function module and the first function module are function modules generated based on different programming languages, and then, the second function module is called to obtain value data corresponding to the target key data from the target data object, and type conversion processing is performed on the value data according to the data type corresponding to the second function module to obtain converted value data corresponding to the target key data.

[0053] It can be seen that the embodiment of the present disclosure utilizes a preset memory structure common to functional modules developed in different programming languages ​​to store transmission data to generate a target data object. By transmitting the target data object, the second functional module can obtain the value data corresponding to the required target key data from the target data object, without the need to perform full serialization and deserialization processing on the transmission data, thereby improving the overall data transmission efficiency between functional modules developed in different programming languages.

[0054] Based on this, an embodiment of the present disclosure provides a data transmission method, which can be applied in a database system. The method is introduced below in conjunction with a specific embodiment.

[0055] Figure 1 The present invention provides a flow chart of a data transmission method provided in an embodiment of the present invention. The method can be executed by a data transmission device, wherein the device can be implemented by software and / or hardware and can generally be integrated in an electronic device. Figure 1 As shown, the method includes:

[0056] S101: Calling a first functional module to generate a target data object based on a preset memory structure.

[0057] Among them, the target data object includes key-value data stored based on the preset memory structure, the preset memory structure includes at least one storage unit, the storage unit includes a key field and a value field, the key field is used to store the key data in the key-value data, and the value field is used to store the value data corresponding to the key data.

[0058] The data transmission method provided by the embodiments of the present disclosure is applied to a client. Specifically, the client can be deployed on a terminal such as a smart phone, a tablet computer, or a desktop computer.

[0059] The first function module in the embodiment of the present disclosure may be any function unit in the cross-language application. The function module may interact with other modules. The function module is used to implement one or more functions in the cross-language application.

[0060] In order to realize data transmission between functional modules of different programming languages, the embodiment of the present disclosure predefines a memory structure, namely, a preset memory structure in the embodiment of the present disclosure, and the preset memory structure is used to store key-value data transmitted between functional modules of different programming languages, namely, key-value data. Key-value data may refer to data stored in the form of key-value pairs. For example, the preset memory structure may be a byte array structure.

[0061] Specifically, the preset memory structure may be composed of at least one storage unit, each storage unit includes a key field and a value field, wherein a storage unit is used to store a pair of key-value data, specifically, the key field in the storage unit is used to store the key data in the key-value data, and the value field is used to store the value data in the key-value data. The number of key-value pairs of key-value data to be transmitted determines the number of storage units used by the target data object.

[0062] like Figure 2 The figure is a schematic diagram of a data transmission process provided by an embodiment of the present disclosure. The preset memory structure 201 includes a storage unit 202 and a storage unit 203, each storage unit includes a key field and a value field, such as the storage unit 202 includes a key field 204 and a value field 205.

[0063] In actual applications, since the preset memory structure is used to store key-value data, before calling the first functional module to generate a target data object based on the preset memory structure, it is also necessary to determine the type of data to be transmitted by the first functional module.

[0064] In an optional implementation, when a first function module calls a second function module, if the data to be transmitted from the first function module to the second function module is key-value data, the first function module is called to store the key-value data based on a preset memory structure to generate a target data object. Specifically, the key-value data is stored using a storage unit in the preset memory structure.

[0065] In another optional implementation, if it is determined that the data to be transmitted by the first functional module does not belong to key-value data, other serialization and deserialization methods may be used for data transmission, which is not limited in the embodiment of the present disclosure.

[0066] Since the storage unit of the preset memory structure includes a key field and a value field, calling the first function module to generate a target data object based on the preset memory structure may include calling the first function module to write the key data in the key-value data to be transmitted into the key field of the storage unit in the preset memory structure, and writing the value data in the key-value data into the value field of the storage unit to obtain the target data object.

[0067] Specifically, the key data and the value data of each pair of key-value data in the key-value data to be transmitted by the first functional module are respectively stored in the key field and the value field of the same storage unit in the preset memory structure.

[0068] S102: Transmit the target data object to a second functional module.

[0069] The second functional module and the first functional module are functional modules generated based on different programming languages.

[0070] The second functional module and the first functional module are functional modules implemented based on different programming languages. For example, the first functional module is implemented based on Java code, and the second functional module is implemented based on C++ code.

[0071] After the first functional module generates the target data object, the target data object is transmitted to the second functional module. There are multiple specific transmission methods. In an optional implementation, after the first functional module is called to generate the target data object based on the preset memory structure, the target data object is transmitted to the second functional module via network transmission.

[0072] In another optional implementation, after calling the first functional module to generate a target data object based on a preset memory structure, the target data object is stored in a preset storage area according to a file storage method, and the second functional module can obtain the transmitted data from the preset storage area based on the file storage address.

[0073] The embodiment of the present disclosure does not limit the manner in which the first functional module transmits the target data object to the second functional module.

[0074] S103: Call the second function module to obtain value data corresponding to the target key data from the target data object, and perform type conversion on the value data according to the data type corresponding to the second function module to obtain converted value data corresponding to the target key data.

[0075] In actual applications, since the key-value data is stored in the storage unit of the preset memory structure, the embodiment of the present disclosure supports the second functional module to obtain the target key-value data from the target data object. In other words, the second functional module does not need to obtain the full amount of the target data object.

[0076] The target key data is the key data in the target key value data that the second functional module needs to obtain. The target key data is used to obtain the corresponding value data.

[0077] In an optional implementation, after obtaining the target data object generated by the first functional module based on the preset memory structure, the second functional module is called to determine the storage unit corresponding to the target key data in the preset memory structure from the target data object based on the target key data, and then, based on the storage unit, obtain the value data corresponding to the target key data from the value field in the storage unit.

[0078] In practical applications, in order to improve the efficiency of determining the storage unit corresponding to the target key data from the target data object, the preset memory structure in the embodiment of the present disclosure also includes a data header, which includes a data volume field, and the data volume field is used to store the number of key-value pairs of the key-value data.

[0079] Specifically, after obtaining the target data object generated by the first functional module based on the preset memory structure, the second functional module is called to obtain the number of key-value pairs stored in the data volume field from the target data object, and then, based on the number of key-value pairs, the storage unit corresponding to the target key data is found in the storage unit of the target data object.

[0080] Among them, based on the number of key-value pairs, the storage unit corresponding to the target key data is searched in the storage unit of the target data object. Specifically, based on the number of key-value pairs, the storage unit corresponding to the target key data can be searched in the storage unit of the target data object using binary search.

[0081] As mentioned above Figure 2 The preset memory structure 201 shown includes a data header, and the data header includes a data amount field 206 .

[0082] In actual applications, in order to avoid reading the data stored in the target data object from the end of the target data object, which may cause inaccurate data reading, the data header in the preset memory structure in the embodiment of the present disclosure also includes a start identification field, which is used to store the data reading start identification of the target data object. The start identification field can be set at the first position in the data header, such as the first two bytes of the data header. Figure 2 The preset memory structure 201 shown includes a data header, and the data header includes a start identification field 207 .

[0083] In an optional implementation, after obtaining the target data object generated by the first functional module based on the preset memory structure, the second functional module is called to detect whether the starting position of the data header of the target data object is the starting identification field. If it is determined that the starting position of the target data object is the starting identification field, it indicates that the target data object is currently being read from the header, and the second functional module can be called to continue to perform subsequent operations.

[0084] In another optional implementation, if it is determined that the starting position of the target data object is not the starting identification field, it indicates that the current position is the tail of the target data object, and the second function module is called to perform subsequent operations from the other end (head) of the target data object.

[0085] The data transmission method provided by the embodiment of the present disclosure specifically comprises: first, calling a first function module to generate a target data object based on a preset memory structure, wherein the target data object includes key-value data stored based on the preset memory structure, the preset memory structure includes at least one storage unit, the storage unit includes a key field and a value field, the key field is used to store key data in the key-value data, and the value field is used to store value data corresponding to the key data; then, the target data object is transmitted to a second function module, wherein the second function module and the first function module are function modules generated based on different programming languages; further, calling the second function module to obtain value data corresponding to the target key data from the target data object, and performing type conversion processing on the value data according to the data type corresponding to the second function module, to obtain converted value data corresponding to the target key data.

[0086] It can be seen that the embodiment of the present disclosure utilizes a preset memory structure common to functional modules developed in different programming languages ​​to store transmission data to generate a target data object. By transmitting the target data object, the second functional module can obtain the value data corresponding to the required target key data from the target data object, without the need to perform full serialization and deserialization processing on the transmission data, thereby improving the overall data transmission efficiency between functional modules developed in different programming languages.

[0087] In actual applications, since the length of the data type of the key-value data to be transmitted by the first functional module is not unique, and the length of the value data stored in the storage unit of the preset memory structure is preset, that is, the length of the value data stored in the storage unit of the preset memory structure is fixed, for example, the length of the value field in the storage unit is 8 bytes.

[0088] Therefore, when the length of the data type of the value data in the key-value data to be transmitted by the first functional module exceeds the length of the value data stored in the storage unit of the preset memory structure, the value data can be stored in a dynamic data field, wherein the dynamic data field can be a part included in the preset memory structure in the embodiment of the present disclosure, and the length of the dynamic data field can change with the change of the length of the data type of the value data.

[0089] As mentioned above Figure 2 The preset memory structure 201 shown includes dynamic data fields.

[0090] In an optional implementation, the value data in the key-value data to be transmitted by the first functional module whose data type is the target data type can be stored in the value field of the storage unit, and the value data in the key-value data whose data type is a non-target data type can be stored in the dynamic data field of a preset memory structure.

[0091] The data type of the value data of the target data type has a fixed length and is smaller than the length of the value field in the storage unit. The target data type may include a basic data type, which may include integer types such as byte, short, int, long, and floating point types such as float and double. The non-target data type may be a non-basic data type, and the length of the non-target data type is not unique.

[0092] On the basis of the above embodiment, in order to determine the data type of the key-value data to be transmitted by the first functional module, the storage unit of the preset memory in the embodiment of the present disclosure may also include a data type field. That is, each storage unit includes a key field, a value field, and a data type field, and the data type field is used to store the data type information of the value data in the storage unit of the preset memory, and the data type information is used to indicate the storage location of the value data. As described above Figure 2 The preset memory structure 201 shown includes a data type field 208 .

[0093] Specifically, after obtaining the target data object generated by the first functional module based on the preset memory structure, the second functional module is called to determine the storage unit corresponding to the target key data from the target data object based on the target key data, and then, obtain the data type information corresponding to the value data in the storage unit from the data type field in the storage unit, and then obtain the value data corresponding to the target key data according to the storage location identified by the data type information.

[0094] In an optional implementation, the storage location identified by the data type information stored in the data type field in the storage unit of the target data object may include a value field in the storage unit. If the storage location identified by the data type information stored in the data type field indicates a value field of the storage unit, it can be represented that the value field in the storage unit currently stores value data corresponding to the target key data.

[0095] In another optional implementation, the storage location identified by the data type information stored in the data type field in the storage unit of the target data object may also include a dynamic data field in a preset memory structure. If the storage location identified by the data type information stored in the data type field indicates a dynamic data field in a preset memory structure, it can be represented that the value field in the storage unit currently does not store the value data corresponding to the target key data. At this time, the dynamic data field in the preset memory structure stores the value data.

[0096] In actual applications, when the storage location identified by the data type information stored in the data type field in the storage unit of the target data object is indicated as a dynamic data field in a preset memory structure, in order to obtain the value data corresponding to the target key data in the dynamic data field, the value field in the storage unit in the preset memory structure in the embodiment of the present disclosure can also be used to store the storage location information of the value data of the non-target data type in the dynamic data field.

[0097] The storage location information of the dynamic data field stored in the value field of the storage unit may include the starting location and the ending location of the value data in the dynamic data field.

[0098] In an optional implementation, after obtaining the target data object generated by the first functional module based on the preset memory structure, the second functional module is called to determine the storage unit corresponding to the target key data from the target data object based on the target key data, and then obtain the data type information corresponding to the value data in the storage unit from the data type field in the storage unit. If the storage position identified by the data type information indicates the value field in the storage unit, the value data corresponding to the target key data is obtained from the value field of the storage unit.

[0099] In another optional implementation, after obtaining the target data object generated by the first functional module based on the preset memory structure, the second functional module is called to determine the storage unit corresponding to the target key data from the target data object based on the target key data, and then obtain the data type information corresponding to the value data in the storage unit from the data type field in the storage unit. If the storage position identified by the data type information indicates a dynamic data field in the preset memory structure, the storage location information of the value data corresponding to the target key data is obtained from the value field in the storage unit, and the value data corresponding to the target key data is obtained from the dynamic data field according to the storage location information.
