Example one
Fig. 1 is a schematic flowchart of a data storage method according to an embodiment of the present invention, which is applicable to a scenario in which data is compressed and then stored in a database.
As shown in fig. 1, a data storage method provided in an embodiment of the present invention includes:
s110, receiving data to be stored transmitted based on a storage request, wherein the data to be stored comprises one or more text fields, and each text field corresponds to a unique field identifier.
The storage request is a request generated when data needs to be stored. The data to be stored refers to data which needs to be stored in a database. Specifically, the data type of the data to be stored is a JAVA data type. The text field refers to a piece of text describing information, such as a name, an age, a JSON (JSON object notation) character string result returned by a certain interface, a message result returned by a certain SDK (Software Development Kit), and the like, and is not limited herein. Specifically, each text field corresponds to a unique field identifier, and the field identifier is an identifier used for determining the specific text field. In this embodiment, optionally, the field identifier may be a field name (e.g., JSON) of the text field, and may also be other identifiers having uniqueness, which is not limited herein.
And S120, judging whether the text field needs to be compressed according to the field identification.
The field identification has uniqueness, so that which text fields need to be compressed and which text fields do not need to be compressed can be judged according to the field identification. Specifically, the field identifier to be compressed may be configured in advance, and which text is to be compressed may be determined according to the field identifier, so that the compression is performed in a targeted manner. If the field identification is configured with a compression function in advance, the text field corresponding to the field identification needs to be compressed. And if the text field needs to be compressed, executing the step S130, and calling a preset compression algorithm to compress the text field based on the configured custom processor. Specifically, during the development of a project, a lot of data to be stored is generated. Some text fields have less data, the repeated data is less, and the compression function is not required to be configured for the text fields; for some text fields with more data (such as returned JSON string results), more repeated data is needed, and in order to reduce the occupied space of the disk, a compression function needs to be configured for the text fields. For example, if a text field exceeds 1MB (megabyte), there must be a lot of data that is repeatedly compressible, and the text field may be configured with a compression function to compress the text field before storing the text field in the database.
In an embodiment, optionally, determining whether the text field needs to be compressed according to the field identifier may include:
judging whether the field identification is configured with a custom processor or not according to the field identification;
and if the field identification is configured with a custom processor, the text field corresponding to the field identification needs to be compressed.
In this embodiment, a custom processor may be configured on the field identifier, and then the custom processor of the field identifier is configured, and the text field corresponding to the field identifier needs to be compressed. The embodiment configures the custom processor by the field identifier, that is, configures the custom processor on the text field. In the mybatis open source framework, when data to be stored is stored, the data type must be converted by a typehandler carried by the mybatis open source framework and then stored in a database. And by configuring the custom processor on the field identifier, the characteristic that the self-contained processor can convert the data type in the open source framework is utilized, the custom processor is configured, and the compression function is executed before the data type is converted.
And S130, calling a preset compression algorithm to compress the text field based on the configured custom processor.
The custom processor refers to a processor improved for the processor with the self-contained open source framework, and the name of the custom processor is different from that of the processor with the self-contained open source framework. For example, if the processor of the mybatis framework is typehandler, the name of the custom processor for compression may be compressshandler, and is not limited herein. In this embodiment, the custom processor is a processor configured with a compression function for a processor provided in the open source framework, and the custom processor compresses a part of text fields in data to be stored, and converts the compressed text fields into a database data format for storage. Alternatively, the open source framework may be a mybatis framework or hibernate framework, and the like, without limitation. For example, when the open source framework is a mybatis framework, the processor of the open source framework is typehandler, and the processor is used as a converter for JAVA data types and database data types. The preset compression algorithm refers to an algorithm for compressing a text field. Optionally, the preset compression algorithm includes, but is not limited to, a GZIP compression algorithm, a deflate compression algorithm, a snappy compression algorithm, or an LZ4 compression algorithm, and is not limited herein.
Specifically, when the mybatis frame is used for storing data to be stored, a typehandler carried in the mybatis frame is required to convert a JAVA data type into a database data type, and then the JAVA data type is stored in the database.
In an embodiment, optionally, the custom processor is configured with a storage address of the preset compression algorithm, and the invoking the preset compression algorithm to compress the text field based on the configured custom processor may include:
and calling the preset compression algorithm from the storage address to compress the text field.
The storage address refers to an address for storing a code of a preset compression algorithm. And when the text field needs to be compressed, calling a preset compression algorithm to compress the text field according to the configured storage address in the custom processor. Illustratively, when the text field A needs to be compressed, a preset compression algorithm is called to compress the text field A, and the JAVA data type is directly converted into the database data type without the need of the compressed text field.
And S140, converting the data type of the compressed data to be stored and storing the data to a database.
After all or part of text fields in the data to be stored are compressed, the compressed data to be stored are converted from the JAVA data type to the database type and then are stored in the database for storage.
In the embodiment, the data type is converted after the text field is compressed, so that the occupied space of the database is reduced. In addition, the efficiency of reading the disk can be improved. The compression process is carried out in the JAVA application program, so that the compression performance is better. In addition, only a corresponding custom processor (such as custom typehandler) needs to be configured for the compressed text field, and the text field which does not need to be compressed does not need to be processed, so that the method is less invasive to the existing code.
In an embodiment, optionally, before the step S130, based on the configured custom processor, invoking a preset compression algorithm to compress the text field, the method may include:
and packaging the preset compression algorithm into a custom tool class.
The custom tool class is a tool class using a related function. In this embodiment, the preset compression algorithm is packaged into a custom tool class, i.e. a compressed tool class. The preset compression algorithm is packaged into the custom tool class, so that the details (such as compressed codes) of the preset compression algorithm are hidden, and the preset compression algorithm is directly used when compression is needed, so that the use convenience is improved.
According to the technical scheme of the embodiment of the invention, the data to be stored transmitted based on the storage request is received, the data to be stored comprises one or more text fields, and each text field corresponds to a unique field identifier;
judging whether the text field needs to be compressed according to the field identification; if the text field needs to be compressed, calling a preset compression algorithm to compress the text field based on a configured custom processor; the compressed data to be stored is subjected to data type conversion and then stored in the database, the text field is compressed before being stored in the database, the size of the compressed data to be stored is smaller than that of uncompressed data to be stored, the occupied space is smaller, and the technical effect of reducing the occupied space of a disk of the database is achieved.
Example two
Fig. 2 is a schematic flowchart of a data query method according to a second embodiment of the present invention, which is suitable for a scenario in which data to be queried stored in a database is queried. The method can be executed by a data query device, which can be implemented in software and/or hardware and can be integrated on a server.
As shown in fig. 2, the data query method provided by the second embodiment of the present invention includes:
s210, receiving data to be inquired transmitted based on the inquiry request, wherein the data to be inquired comprises one or more text fields, and each text field corresponds to a unique field identifier.
The query request refers to a request generated when data needs to be queried. The data to be queried refers to data needing to be queried. Specifically, the data to be queried is stored in a database and transmitted from the database to the JAVA application. The data type of the data to be queried is the data type of the database. The text field refers to a piece of text for describing information, such as a name, an age of a user, a JSON (JSON Object Notation) character string result returned by an interface, a message result returned by an SDK (Software Development Kit), and the like, and is not limited herein. Specifically, each text field corresponds to a unique field identifier, and the field identifier is an identifier used for determining the specific text field. In this embodiment, optionally, the field identifier may be a field name (e.g., JSON) of the text field, and may also be other identifiers having uniqueness, which is not limited herein.
And S220, converting the data type of the data to be queried.
The data to be queried stored in the database is the data type of the database, so the data type of the data to be queried needs to be converted. Specifically, the data to be queried is converted from the data type of the database into the JAVA data type, so as to satisfy the use query in the JAVA application.
And S230, judging whether the text field needs to be decompressed according to the field identification.
The field identifier has uniqueness, so that which text fields need to be decompressed and which text fields do not need to be decompressed can be judged according to the field identifier. Specifically, the field identifier that needs to be decompressed can be configured in advance, and which text needs to be decompressed can be determined according to the field identifier, so that decompression can be performed in a targeted manner. If the field identification is configured with the decompression function in advance, the text field corresponding to the field identification needs to be decompressed. If the text field needs to be decompressed, step S240 is performed. Specifically, decompression is required for text fields that are decompressed for storage in the database.
In an embodiment, optionally, determining whether the text field needs to be decompressed according to the field identifier may include:
judging whether the field identification is configured with a custom processor or not according to the field identification;
and if the field identification is configured with a custom processor, decompressing the text field corresponding to the field identification.
In this embodiment, a custom processor may be configured on the field identifier, and then the custom processor configured with the field identifier needs to decompress a text field corresponding to the field identifier. The embodiment configures the custom processor by the field identifier, that is, configures the custom processor on the text field. In the mybatis open source framework, when data to be queried is queried, the data type needs to be converted by a typehandler provided by the mybatis open source framework, and then the query is performed. And by configuring the custom processor on the field identifier, the characteristic that the self-contained processor can convert the data type in the open source framework is utilized, the custom processor is configured, and the decompression function is executed after the data type is converted.
S240, based on the configured custom processor, calling a preset decompression algorithm to decompress the text field.
The custom processor refers to a processor improved for the processor with the self-contained open source framework, and the name of the custom processor is different from that of the processor with the self-contained open source framework. For example, if the processor of the mybatis framework is typehandler, the name of the custom processor used for decompression may be decompenssharandler, and is not limited herein. In this embodiment, the custom processor is a processor configured with a decompression function for a processor provided with an open source framework, and decompresses a part of the text field by using the custom processor after converting the data type of the data to be queried by using the processor provided with the open source framework. Alternatively, the open source framework may be a mybatis framework or hibernate framework, and the like, without limitation. For example, when the open source framework is a mybatis framework, the processor of the open source framework is typehandler, and the processor is used as a converter for JAVA data types and database data types. The preset decompression algorithm refers to an algorithm for decompressing a text field. Optionally, the preset decompression algorithm includes, but is not limited to, a GZIP decompression algorithm, a deflate decompression algorithm, a snappy decompression algorithm, or an LZ4 decompression algorithm, and is not limited herein.
Specifically, when a mybatis framework is used for querying a query, a typehandler carried in the mybatis framework is required to convert the data type of the database into a JAVA data type, and then a user-defined processor is used for decompression.
In an embodiment, optionally, the configuring, by the custom processor, a storage address of the preset decompression algorithm, and the invoking, by the configured custom processor, the preset decompression algorithm to decompress the text field may include:
and calling the preset decompression algorithm from the storage address to decompress the text field.
The storage address refers to an address for storing a code of a preset decompression algorithm. When the text field needs to be decompressed, a preset decompression algorithm is called to decompress the text field according to the configured storage address in the user-defined processor. Illustratively, when the text field a needs to be decompressed, a preset decompression algorithm is called to decompress the text field a, and the data type of the database is directly converted into the JAVA data type without the decompressed text field.
And S250, sending the decompressed data to be queried to a user for query.
After all or part of text fields in the data to be queried are decompressed, the decompressed data to be queried is sent to a user for query.
In this embodiment, the data to be queried is stored in the database, and a part of the text field is compressed, so that the occupied space of the database is reduced, and when the query is needed, the query can be performed by decompressing the data to be queried. In addition, the efficiency of reading the disk can be improved. The decompression process is carried out in the JAVA application program, so that the decompression performance is better. In addition, only a corresponding custom processor (such as custom typehandler) needs to be configured for the decompressed text field, and the text field which does not need decompression processing does not need to be processed, so that the method is less invasive to the existing code.
In an embodiment, optionally, before invoking a preset decompression algorithm to decompress the text field based on the configured custom processor in step S240, the method may include:
and packaging the preset decompression algorithm into a user-defined tool class.
The custom tool class is a tool class using a related function. In this embodiment, the preset decompression algorithm is packaged into a custom tool class, i.e. a decompressed tool class.
