[0002] In the system based on the MPP big data analysis engine IMPALA, a separate storage solution is generally adopted for heterogeneous data. Data with the same data organization form is stored in the same data table, or heterogeneous data is serialized into strings using JSON and stored in the same data table. When creating a data table in a general database, the data name and data type of each field need to be clearly specified.

[0058] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0059] The heterogeneous data encoding and decoding method provided in this application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the server 104 through a network. The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0060] In one embodiment, Figure 2 As shown, a heterogeneous data encoding method is provided, which is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0061] Step 202, obtaining heterogeneous data to be encoded; each field in the heterogeneous data to be encoded is assigned a unique identification value.

[0062] Specifically, the heterogeneous data to be encoded contains no less than one field, and each field is assigned a unique identification value through the metadata management platform. The unique identification value is also called an id value in this embodiment; the id value is used to sort and store the fields in the heterogeneous data to be encoded, which facilitates the use of binary search for fast retrieval when retrieving specific fields of the heterogeneous data to be encoded; the metadata management platform assigns a unique identification value to each field, which is conducive to saving storage space.

[0063] Step 204, converting the to-be-encoded heterogeneous data into an ordered mapping table structure; the ordered mapping table structure includes the field value of each field and the unique identification value of each field, and the field name of each field and the unique identification value of each field are mapped one by one.

[0064] Specifically, the heterogeneous data to be encoded is converted into an ordered mapping table structure. This ordered mapping table can be a tree data structure implemented by a balanced binary tree. The ordered mapping table structure contains the field value of each field and the unique identification value of each field. The field name of each field and the unique identification value of each field are mapped one-to-one, that is, the heterogeneous data to be encoded is converted into mapping data in which the unique identification value of each field corresponds to the field name of each field, such as a TreeMap structure in which the unique identification value of each field corresponds to the field name of each field.

[0065] Step 206: Encode the ordered mapping table structure to generate an encoded byte stream.

[0066] Specifically, after obtaining the ordered mapping table structure, the ordered mapping table structure is encoded to generate an encoded byte stream; wherein the encoded data structure includes at least one of a modulus, an index rule, an index area, and data value information; the index area contains multiple index records; the modulus is used to mark the version number of the encoded data structure; each index record contains at least one of a field identification value, a length of the field value, and an offset of a storage location of the field value; the offset of the storage location of the field value is used to determine the position of the field.

[0067] In the above-mentioned heterogeneous data encoding method, heterogeneous data to be encoded are obtained, each field in the heterogeneous data to be encoded is assigned a unique identification value, and the heterogeneous data to be encoded are converted into an ordered mapping table structure, the ordered mapping table structure contains the field value of each field and the unique identification value of each field, the field name of each field and the unique identification value of each field are mapped one by one, the ordered mapping table structure is encoded, and an encoded byte stream is generated. By converting the heterogeneous data to be encoded into an ordered mapping table structure, storage space is saved and decoding performance is improved.

[0068] In one embodiment, converting the to-be-encoded heterogeneous data into an ordered mapping table structure comprises:

[0069] Obtaining the field name of each field in the heterogeneous data to be encoded;

[0070] The field name of each field in the to-be-encoded heterogeneous data is matched one-to-one with the unique identification value of each field to obtain an ordered mapping table structure.

[0071] Specifically, when converting the heterogeneous data to be encoded into an ordered mapping table structure, first obtain the field name of each field in the heterogeneous data to be encoded, such as age, name, etc. When age = 28, age is the field name, and 28 is the field value corresponding to the field; then, map the field name of each field in the data to be encoded to the unique identification value of the field one by one, so that the original field name and field value can be converted into an ordered mapping table of the field unique identification id and the field value.

[0072] In this embodiment, the field name of each field in the to-be-encoded heterogeneous data is obtained, and each field name in the to-be-encoded heterogeneous data is mapped one by one to a unique identification value corresponding to the field, thereby converting the original heterogeneous data into an ordered mapping table structure of field unique identification values ​​and field values, wherein the field name and the unique identification value of the field are stored in a metadata platform, so that when the encoded data is decoded, it has the advantages of fast decoding speed and maintaining its original field name.

[0073] In one embodiment, encoding the ordered mapping table structure to generate an encoded byte stream includes:

[0074] Based on the ordered mapping table structure, generating an index area and data value information corresponding to the ordered mapping table structure; the index area includes a plurality of index records;

[0075] Based on the index area and data value information corresponding to the ordered mapping table structure, an encoded byte stream is generated.

[0076] Specifically, when encoding the ordered mapping table, based on the ordered mapping table structure, the index area and data value information corresponding to the ordered mapping table structure are generated; according to the index area and data value information corresponding to the ordered mapping table structure, the encoded data structure is generated. The encoded data structure includes at least one of a modulus, an index rule, an index area, and data value information; wherein the modulus is equivalent to the version number of the encoded data structure, which is used for updating, and the modulus is not required when the encoded data structure does not need to be updated. The index area contains multiple index records, wherein each index record contains at least one of a field identification value, a length of the field value, and an offset of a storage location of the field value, and the offset of the storage location of the field value is used to determine the location of the field.

[0077] In this embodiment, based on the ordered mapping table structure, the index area and data value information corresponding to the ordered mapping table structure are generated, and based on the index area and data value information corresponding to the ordered mapping table structure, the encoded byte stream is generated. By encoding the index area and data value information of the ordered mapping table structure, the storage space occupied by the heterogeneous data to be encoded is reduced, and the decoding performance can be improved.

[0078] In one embodiment, generating an encoded byte stream based on the index area and data value information corresponding to the ordered mapping table structure includes:

[0079] Merging the index area and data value information corresponding to the ordered mapping table structure to obtain merged data;

[0080] The combined data is used as an encoded byte stream.

[0081] Specifically, when encoding according to the index area and data value information corresponding to the ordered mapping table structure, the index area and data value information corresponding to the ordered mapping table structure are merged to obtain the merged data, and the merged data is used as an encoded byte stream, and the encoded byte stream contains the index area and data value information.

[0082] In this embodiment, the index area and data value information corresponding to the ordered mapping table structure are merged and processed, and the merged data is obtained as the encoded byte stream. By merging the index area and the data value information, encoding of the heterogeneous data to be encoded is achieved, the storage space occupied by the heterogeneous data to be encoded is reduced, and the decoding performance can be improved.

[0083] In one embodiment, Figure 3 As shown, a heterogeneous data decoding method is provided, which is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0084] Step 302, obtaining field information of each field in the heterogeneous data to be decoded; the heterogeneous data to be decoded is an encoded byte stream; the field information includes a unique identification value of each field.

[0085] Specifically, decoding the encoded byte stream first requires obtaining the field information of each field in the heterogeneous data to be decoded, and the field information of each field can be obtained by querying the metadata management platform; the field information here includes the field identification value (the field name can be obtained through the mapping relationship between the field name and the field's unique identification value), the field type and the field name. Among them, the heterogeneous data to be decoded contains no less than one field, and each field contains a unique identification value assigned by the metadata management platform. The unique identification value is also called an id value in this embodiment; the id value is used to sort and store each field in the heterogeneous data to be decoded, and it is convenient to use binary search for fast retrieval when retrieving specific fields of the heterogeneous data to be decoded.

[0086] Step 304 : Generate a data table view of the heterogeneous data to be decoded based on the field information of each field in the heterogeneous data to be decoded and the mapping relationship between the field name of each field and its corresponding unique identification value.

[0087] Specifically, a data table view of the heterogeneous data to be decoded is generated based on the information of each field in the heterogeneous data to be decoded, and the mapping relationship between each field and its corresponding unique identification value; wherein the data table view is a logical table that can be queried and analyzed using SQL syntax.

[0088] Step 306: If the unique identification value corresponding to each field can be queried in the data table of the heterogeneous data to be decoded, the heterogeneous data to be decoded is decoded to obtain decoded data.

[0089] Specifically, the query is performed based on the unique identification value of the field to be queried. If the unique identification value corresponding to each field can be queried in the data table view of the heterogeneous data to be decoded, the heterogeneous data to be decoded is decoded according to the unique identification value of each field to obtain the field value corresponding to the unique identification value, that is, the decoded data.

[0090] In this embodiment, field information of each field in the heterogeneous data to be decoded is obtained, and a data table view of the heterogeneous data to be decoded is generated based on the information of each field in the heterogeneous data to be decoded and the mapping relationship between each field and its corresponding unique identification value. When the unique identification value corresponding to each field can be queried in the data table of the heterogeneous data to be decoded, the heterogeneous data to be decoded is decoded to obtain the decoded data. The decoded fields are obtained by constructing a data table view of the heterogeneous data to be decoded, thereby improving the decoding efficiency.

[0091] In one embodiment, the decoding process of the to-be-decoded heterogeneous data to obtain decoded data includes:

[0092] Obtaining index area and data value information corresponding to the heterogeneous data to be decoded;

[0093] Decoding is performed based on the index area and data value information corresponding to the heterogeneous data to be decoded to obtain decoded data.

[0094] Specifically, a traversal query is performed based on the unique identification value, and based on the index area corresponding to the heterogeneous data to be decoded, multiple index records in the index area are obtained. When the unique identification value is matched in the index record in the index area, the offset of the field value storage location is obtained, and the position of the field is determined by the offset of the field value storage location to obtain the decoded data value.

[0095] In this embodiment, the index area and data value information corresponding to the heterogeneous data to be decoded are obtained, decoding processing is performed based on the index area and data value information corresponding to the heterogeneous data to be decoded, and the decoded data is obtained. By querying and matching the unique identification value in the index area, fast decoding of the encoded data is achieved, thereby improving the decoding rate.

[0096] In one embodiment, performing decoding processing based on the index area and data value information corresponding to the heterogeneous data to be decoded to obtain the decoded data includes:

[0097] The unique identification value in the field information is searched in the index area. When the unique identification value is the same as the corresponding unique identification value in an index entry in the index area, the corresponding value can be obtained according to the data value information associated with the index entry.

[0098] Specifically, an index record is obtained from the index area, and a search is performed in the index area according to the unique identification value of the field information. When the unique identification value is the same as the unique identification value in a certain index entry in the index area, the value corresponding to the keyword is obtained according to the data value information as the decoded data. When searching in the index area according to the unique identification value of the field information, a search can be performed by binary search to determine whether the unique identification values ​​are the same. If they are the same, the field value corresponding to the unique identification value is obtained, and then the value corresponding to the keyword is obtained as the decoded data. If the unique identification values ​​are different, determine whether the unique identification value is greater than the unique identification value in the middle index record within the index range. If it is greater, continue to search from the index area after the middle index entry until the unique identification values ​​are the same; similarly, if it is less, continue to search from the index area before the middle index entry until the unique identification values ​​are the same, and obtain the value corresponding to the same unique identification value as the decoded data.

[0099] In this embodiment, index records are obtained based on the index area, and a search is performed in the index area according to the unique identification value in the field information. When the unique identification value is the same as the unique identification value in an index entry in the index area, the value corresponding to the keyword is obtained as the decoded data according to the data value information, and the unique identification value is matched through binary search, thereby improving the matching efficiency of the unique identification value and the decoding rate.
