S103, determining a sending sequence according to the target generation time, and sending the task information in the information table to be sent according to the sending sequence.
In this embodiment, in the Kafka system, task information of an earlier generation time is to be preferentially sent, and the task information in the information table to be sent may be sent according to a target generation time and/or an initial generation time in the information table to be sent, and a corresponding order.

Example two
Fig. 2 is a flowchart of a method for sending information in order according to a second embodiment of the present invention, where the technical solution of the second embodiment of the present invention is further optimized based on the foregoing optional technical solutions, and a manner for sending different Topic messages in order is given.
Optionally, the determining a sending sequence according to the target generation time includes: and determining the scanning interval time of the information table to be sent, and scanning the information table to be sent once every time the scanning interval time passes to determine the sending sequence of the task information in the information table to be sent, wherein the scanning interval time is less than or equal to the time interval. The advantage of this arrangement is that by setting a reasonable scanning time, the task information in the information table to be sent can be guaranteed to be sent on time.
Optionally, the determining, based on the characteristics of the task request and the task information flow, a time interval, a pre-sending sequence, and a topic of the task information in the task information flow includes: according to a task request, determining initial generation time, interval time and a pre-sending sequence of each task information in a task information stream, wherein the task information stream comprises a plurality of task information; and determining the theme of each task information in the task information flow according to the characteristics of each task information in the task information flow. The advantage of this arrangement is that by determining the initial generation time, time interval, subject and pre-transmission sequence of each task information, it provides assurance that the task information will be transmitted accurately.
Optionally, if the theme corresponds to multiple different theme types, determining target generation time of the task information based on the time interval, the pre-sending sequence, and the initial generation time, and writing the task information into an information table to be sent, including: if the theme corresponds to multiple different theme types and the time interval is greater than zero, determining first task information in the task information according to the time interval of the task information and the pre-sending sequence; adjusting the initial generation time of the first task information based on the time interval to obtain target generation time; and writing the first task information and the second task information into an information table to be sent, wherein the task information comprises the first task information and the second task information, and the second task information is corresponding to the generation time which is not adjusted. This arrangement is advantageous in that since task information of earlier generation time is to be transmitted preferentially in the Kafka system, the transmission order of task information can be set by changing the initial generation time.
Optionally, after the sending of the task information in the information table to be sent, the method further includes: and generating actual sending time of the task information, deleting the task information from the information table to be sent, and adding the actual sending time and the task information into a sent history table. The advantage of setting up like this is, according to comparing the time of sending in advance of the task information with actual sending time, can check whether the sending sequence of the task information satisfies the corresponding sending sequence in the time of sending in advance.
As shown in fig. 2, a method for sending information in order provided in the second embodiment of the present invention specifically includes the following steps:
s201, according to the task request, determining the initial generation time, the time interval and the pre-sending sequence of each task information in the task information flow.
The task information flow comprises a plurality of task information.
Specifically, the initial generation time, the time interval, the pre-transmission order, the key value, the information body, and the like of the task information may be configured according to the service requirement or the task request of the concumer.
S202, determining the theme of each piece of task information in the task information flow according to the characteristics of each piece of task information in the task information flow.
For example, if the task information is characterized by modifying an a database table of a certain storage area in the Kafka cluster, the task information may be determined as a topic a, and if the task information is characterized by modifying a B database table of a certain storage area in the Kafka cluster, the task information may be determined as a topic B.
S203, if the theme corresponds to multiple different theme types and the time interval is greater than zero, determining first task information in the task information according to the time interval of the task information and the pre-sending sequence.
Specifically, the first task information may be task information that is subsequent to the task information that is ranked first in the pre-transmission order, i.e., is transmitted first.
For example, if the time interval is one minute, the topic types of the topic a and the topic B are different, the initial generation time of the task information of the topic a is 8 am, the initial generation time of the task information of the topic B is also 8 am, and the pre-transmission order is that a precedes B, the task information of the topic B may be determined as the first task information.
S204, adjusting the initial generation time of the first task information based on the time interval to obtain target generation time.
Specifically, the target generation time of the first task information may be determined as a time corresponding to a time interval later than the initial generation time of the theme a.
Optionally, the adjusting the initial generation time of the first task information based on the time interval to obtain a target generation time includes: and when the initial generation time of the plurality of task information is the same, calculating the sum of the initial generation time of the first task information and the interval time to obtain target generation time.
Illustratively, as described in the above example, the initial time of the task information of the topic B may be adjusted to 8 am 1 minute.
Optionally, the adjusting the initial generation time of the first task information based on the time interval to obtain a target generation time includes: when the initial generation times of the plurality of pieces of task information are different, the sum of the initial generation time of the second piece of task information and the interval time in the plurality of pieces of task information can be calculated to obtain a target generation time.
For example, if the time interval is 5 minutes, the initial generation time of the task information of the topic a is 8 am, the initial generation time of the task information of the topic B is 8 am 1 min, the initial generation time of the task information of the topic C is 8 am 2 min, the pre-transmission sequence is that a precedes B and B precedes C, the task information of the topic B and the topic C may be determined as the first task information, the task information of the topic a is determined as the second task information, and the target generation times of the task information of the topic B and the topic C are both 8 am 5 min.
S205, writing the first task information and the second task information into an information table to be sent.
The task information comprises the first task information and the second task information, and the second task information is corresponding to the production time which is not adjusted.
Illustratively, as described in the above example, the task information of the subject a, the subject B, and the subject C may be written in the to-be-transmitted information table.
Optionally, if the theme corresponds to multiple different theme types and the time interval is equal to zero, storing the task information of the theme in an information table to be sent; and when the initial generation time of the task information is the same, simultaneously sending the task information in the information table to be sent.
For example, if the time interval is zero, the task information of the topic a and the topic B may be directly written into the information table to be sent, and if the initial generation time of the topic a and the initial generation time of the topic B are the same, the task information of the topic a and the task information of the topic B may be sent at the same time.
S206, determining the scanning interval time of the information table to be sent, and scanning the information table to be sent once every time the scanning interval time passes so as to determine the sending sequence of the task information in the information table to be sent.
Wherein the scan interval time is less than or equal to the time interval.
For example, as described in the above example, if the time interval is 5 minutes, and the information table to be sent only includes the task information of the topic a, the topic B, and the topic C, the scanning interval time may be set to 5 minutes, that is, the information table to be sent is scanned every 5 minutes, and since the initial generation time of the topic a is prior to the target generation time of the topic B and the topic C, it may be determined that the sending sequence of the task information in the information table to be sent is that the task information of the topic a is sent first, and the task information of the topic B and the task information of the topic C are sent again when the next scanning is performed, that is, after 5 minutes.
And S207, sending the task information in the information table to be sent according to the sending sequence.
S208, generating the actual sending time of the task information, deleting the task information from the information table to be sent, and adding the actual sending time and the task information into a sent history table.
For example, as described in the above example, after the task information of the topic a is sent, the time corresponding to the current sending is determined as the actual sending time of the task information, the task information of the topic a is deleted from the to-be-sent information table, and the actual sending time of the task information of the topic a and the task information are added to the sent history table.
The method for orderly sending the information determines the pre-sending sequence, the initial generating time, the time interval, the theme and the like of the task information according to the characteristics of the task request and the task information flow, then updates the target generating time and the second task information of the first task information in the task information according to the pre-sending sequence and the time interval, stores the first task information and the second task information into an information table to be sent, determines the scanning time interval of the information table to be sent, finally sends the task information in the information table to be sent according to the target generating time and/or the sequence of the initial generating time in the information table to be sent, reasonably determines the sending sequence of the task information with different themes according to the pre-sending sequence and the time interval of the task information, and pointedly increases the initial generating time of the task information needing to be sent later based on the principle of sending data by a Kafka system, thereby realizing the effect of sending different Topic information when a Producer generates a plurality of orderly Topic messages with different Topic.
