A first embodiment, namely, an embodiment of a method of data processing, is provided for the present disclosure.

The embodiments of the present disclosure will be described in detail with reference to fig. 1, fig. 2 and fig. 3, wherein fig. 1 is a schematic diagram illustrating a conventional data processing method; FIG. 2 shows a schematic diagram of a method of data processing according to an embodiment of the present disclosure; FIG. 3 shows a schematic diagram of a method of data processing according to an embodiment of the present disclosure; FIG. 4 shows a flow diagram of a method of data processing according to an embodiment of the present disclosure.

Referring to fig. 4, step S401 receives a request message through a port of a first short connection.

The port is an outlet for communication between the equipment and the outside. The ports in the embodiments of the present disclosure are virtual ports, where a virtual port refers to a port inside a computer or inside a switch router, and the virtual port is invisible. For example, a hypertext Transfer Protocol (HTTP) proxy server is commonly used with the following ports: 80/8080/3128/8081/9098, respectively; the firewall security session conversion Protocol (abbreviated as SOCKS for short) proxy Protocol server commonly uses the following ports: 1080; the File Transfer Protocol (FTP) is commonly used as a port of a proxy server: 21; a common port of a Telnet (Telecommunications Network, abbreviated as Telnet) protocol proxy server is as follows: 23.

referring to fig. 1, conventionally, a database long connection is established between a remote terminal and a database server for processing a database, and a database processing instruction is sent through the database long connection. It may happen that a plurality of remote terminals establish their own dedicated database long connection with the database simultaneously for the same request message. Therefore, a large amount of resources of the database server are occupied, the system performance of the database server is seriously influenced, and the efficiency of the database server is reduced.

The disclosed embodiments are based on a method of generating an idempotent concept. The idempotency means that the effect of executing any number of times in a program is the same as the effect of executing one time.

A database long connection is a channel that exchanges data with multiple databases.

The long connection of the database is the information which is established in the memory at the data abstraction layer and is connected with the database. The long connection of the database is stored in the memory, so that the time of each connection can be shortened, and the data processing speed is improved.

Referring to fig. 2 and 3, the port receiving the request message through the first short connection does not obtain the database processing instruction through the database long connection, but establishes a data abstraction layer between the remote terminal and the database. And the data abstraction layer receives the request messages sent by each remote terminal through the port of the first short connection, classifies the request messages according to different request contents, establishes a database long connection between each type and the database, and acquires data results returned by the database through the corresponding database long connection. Therefore, the number of long connections of the database is reduced, and the resource reuse rate is improved.

The request message may be generated according to HTTP, or may be generated in an RPC call manner or a custom manner. The disclosed embodiments are not particularly limited.

The short connection is a stateless communication connection established between the remote terminal and the data abstraction layer, so that the resource occupancy rate can be reduced. The user experience is improved.

Optionally, the receiving a request message through a port of the first short connection includes the following steps:

step S401-1, receiving a request message sent by a first function through the port of the first short connection.

For example, for the FaaS architecture, a function of a process in the remote terminal sends a request message, and meanwhile, the remote terminal is in stateless communication connection with the data abstraction layer (for example, a User Datagram Protocol (UDP), or HTTP) is adopted); when the functions in the FaaS architecture are very many, the efficiency of the remote terminal process is not affected.

Step S402, analyzing the request message and obtaining a database instruction.

Typically, the request message includes protocol header information and protocol body information.

The protocol header information includes information of the communication protocol and information associated with the protocol body. For example, the protocol header information of the request message of HTTP includes: protocol type, target domain name and port, source domain name and port, uniform resource identifier, receivable data type, compression mode, language, connection mode.

The protocol body information includes the request content sent by the requester.

Since the request message is transmitted by encapsulating a plurality of different types of information in a message according to a preset format in the form of a communication protocol, the request message needs to be restored to information that can be directly utilized after the request message is received.

The analysis is to analyze the message according to a preset format and restore the information in the message.

The analyzing the request message to obtain the database instruction comprises the following steps:

step S402-1, acquiring protocol transmission rules according to the request message.

For example, the request message is a message encapsulated according to HTTP, and the protocol type obtained by the protocol header information of the request message is HTTP type, the protocol transmission rule of the request message is HTTP.

Step S402-2, the request message is analyzed based on the protocol transmission rule, and first protocol body information and first protocol header information are obtained.

And step S402-3, acquiring the request type and the request content according to the first protocol body information and a preset request body information rule.

The preset request body information rule is a preset rule for organizing protocol body information of the request message, so that the data abstraction layer can acquire correct information according to the preset request body information rule.

Since the first protocol body information includes multiple types of information, if the information is to be placed in a message, the information needs to be organized according to a preset request body information rule to generate the first protocol body information.

The first protocol body information in the embodiments of the present disclosure includes a request type and a request content. For example, if the request message is to query the database content, the request type is 1, and the request content includes: the method comprises the following steps of (1) inquiring fields, inquiring database names, table names corresponding to the database and constraint conditions; if the request message is inserted into the database content, the request type is 2, and the request content includes: inserting fields and field values, names of inserted databases, names of tables corresponding to the databases and constraint conditions; the request type for deletion is 3; the modified request type is 4.

Optionally, the obtaining the request type and the request content according to the first protocol body information and a preset request body information rule includes the following steps:

step S402-3-1, judging whether the format of the first protocol body information accords with the byte stream format.

The byte stream is composed of bytes and the character stream is composed of characters. A Java hash character consists of two bytes. Byte streams are the most basic, and all subclasses of InputStream and OutputStream are byte streams, primarily used for processing binary data. For example, a byte stream format, including: the JSON format.

And step S402-3-2, if yes, performing deserialization processing on the first protocol body information, and acquiring a request type and request content according to a preset request body information rule.

Deserialization is the process of converting the byte stream into information that the preset request body information rules can identify.

And step S402-4, acquiring the database instruction according to the request type and the request content.

The database instructions include processing instructions for a plurality of databases. Also, a plurality of instructions to the database are included. Such as batch instructions to a database.

Step S403, determining whether a resource pool includes a database long connection associated with the database instruction.

A resource pool is a configuration mechanism and is a collection for storing long connections of a database. The resource pool organizes the database long connections together according to a preset sorting rule, and the database long connections are effectively managed. The speed of searching long connections of the database can be improved.

In a resource pool, the characteristics of the database instructions are associated with database long connections. For example, the queried database and the set of data tables in the database make up the features of the database instruction.

And S404, if yes, acquiring a first data result according to the database instruction and the database long connection.

The first data result is the data result that the database returned to the data abstraction layer according to the database instruction.

Step S405, if not, a database long connection associated with the database instruction is established, and the first data result is obtained according to the database instruction and the database long connection.

Optionally, after the database long connection associated with the database instruction is established, the method further includes the following steps:

and S405-1, storing the database long connection into the resource pool.

In order to ensure that the first data result can be correctly returned to the remote terminal sending the request message, optionally, the method further includes the following steps:

step S406, a first association relationship between the first protocol header information and the database long connection is established.

Because the database long connection is established according to or associated with the database instruction; and the database instruction is derived from the first protocol body information, so that the first protocol head information associated with the first protocol body information can establish a first association relation with the database long connection.

Step S407, obtaining the corresponding first protocol header information according to the first data result and the first association relationship.

For example, the first association relationship may be represented by a handle of the first data result, that is, the handle corresponds to the long connection of the database and further corresponds to the first protocol header information, and after the first data result is obtained, the first protocol header information may be obtained through the handle.

The purpose of the acquired first protocol header information is to acquire communication information of a corresponding remote terminal.

Step S408, generating a request response message according to the first protocol header information, the first data result, and a preset response body information rule.

The request response message is response information generated by the data abstraction layer according to the request of the request message. Typically, the request response message includes protocol header information and protocol body information.

The protocol header information includes information of the communication protocol and information associated with the protocol body. For example, the protocol header information of the request response message of HTTP includes: protocol type, response time, control buffer mode, byte stream identification, compression mode and connection mode.

The protocol body information includes response contents transmitted by the responder.

The preset response body information rule is a preset rule for organizing the protocol body information of the request response message according to the first data result. So that the remote terminal can acquire correct information according to the preset information rule of the response body.

The method specifically comprises the following steps:

step S408-1, second protocol body information is generated according to the first data result and a preset response body information rule.

Optionally, the method comprises the following steps:

step S408-1-1, judging whether the format of the first protocol body information accords with the byte stream format.

For example, a byte stream format, including: the JSON format.

And step S408-1-2, if so, processing the first data result according to a preset response body information rule to generate a second data result, and performing serialization processing on the second data result to acquire the second protocol body information.

The serialization process is a process of converting information (i.e., the second data result) generated according to the preset response body information rule into a byte stream.

Step S408-2, generating second protocol header information according to the second protocol body information and the first protocol header information.

Information of the communication protocol associated with the remote terminal that issued the request message, i.e., the second protocol header information, can be obtained from the first protocol header information. For example, the protocol header information of the request response message may be obtained from the protocol header information of the request message of HTTP, including: protocol type, source domain name and port, compression mode and connection mode.

Step S408-3, generating the request response message based on the second protocol header information and the second protocol body information.

After the data abstraction layer obtains the response information, the response information can be returned to the remote terminal.

Optionally, after generating a request response message according to the first protocol header information, the first data result, and a preset response body information rule, the method further includes the following steps:

step S409, establishing a second short connection associated with the request response message.

Since the first short connection automatically disconnects the connection with the data abstraction layer after the remote terminal has transmitted the request message, the data abstraction layer needs to reestablish a new short connection with the remote terminal when returning the request response message to the remote terminal, that is, the second short connection.

Step S410, sending the request response message through the port of the second short connection.

The embodiment of the disclosure realizes idempotent processing and meets the requirement of short connection under the FaaS architecture. The number of long connections of the database is reduced, and the resource reuse rate is improved. Flexible expandability enables users to realize the expansion capacity of bottom-layer resources in an imperceptible state.
