Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The words involved in the present solution are explained as follows:
batch processing: the IT system processes data into two categories, namely online transaction and batch processing, wherein the online transaction refers to an information processing mode which is initiated through various terminal devices and needs to respond in time through multiple channels, the processing time is short, and the timeliness is high. The batch processing refers to a process of processing accumulated data generated by the system in a certain period at a specific time according to business requirements and technical schemes, the processing time is relatively long, the processing efficiency is high, and the requirements of final daily processing, statistical settlement, report analysis and the like can be met.
Batch Task (Task): a job chain consisting of one or more batch jobs.
Batch Job (Job): a single batch job is a step in the Task.
Batch Step (Step): a step in a single batch Job Job.
ETL: an abbreviation of Extract-Transform-Load, i.e., a process of data extraction, transformation, and loading.
The detailed comparison between the prior art key and DataStage and the present scheme is described here:
1. the key is an open-source ETL tool for processing, converting, migrating, etc. various data. The key is developed by the client, and configuration development and management are difficult to complete when a large number of jobs are handled. And the transaction function support is weak, and the support for the complex operation flow needing transaction control is insufficient. The scheme provides three-level Task-Job-Step flow control, can be flexibly configured, basically has the perfect transaction control function of Spring Batch, and can meet the transaction processing requirement on a complex flow.
2. The DataStage supports the functionality, flexibility and scalability of data integration requirements, supports various complex data transformation and processes and the like. The Datastage tool is heavy, has high requirements on hardware, has weak self scheduling function, and generally needs to additionally develop a scheduling and monitoring program under the condition of a large amount of operation. And the transaction function support is weak, and the support for the complex operation flow needing transaction control is insufficient. The positioning problem is difficult under the condition of processing the operation exception. The scheme integrates the operation scheduling and batch processing functions, can run in a single machine environment and also supports cluster mode running. The method supports flexible scheduling configuration, supports perfect transaction processing function, provides a built-in batch tool, and is convenient and fast in customizing operation flow. The abnormal processing flow can be quickly positioned to the problem reason, and the system operation and maintenance are convenient.
Referring to fig. 1, a main flowchart of a task processing method according to an embodiment of the present invention is shown, including the following steps:
s101: determining a batch processing task to be executed, acquiring fragmentation parameters from the attributes of the batch processing task, and judging whether the fragmentation parameters are set to preset values; wherein one batch processing task comprises a plurality of data to be processed;
s102: if the judgment result is yes, determining a plurality of devices for processing the plurality of data, respectively distributing different data to corresponding devices for processing, summarizing the processing result, and obtaining an execution result;
s103: if the judgment result is negative, determining one device which processes the plurality of data together, and distributing the plurality of data together to the one device for processing to obtain an execution result.
In the above embodiment, for step S101, a task scheduling period, that is, a task execution interval is set in advance, and is executed, for example, once every 22 nights, or once every month, once every 5 minutes, or once every 1 minute. And pulling a plurality of batch processing tasks to be executed from the database/operation path according to the configured task scheduling period, and arranging according to the pulling sequence to generate a task queue to be executed, wherein the queue comprises the plurality of batch processing tasks. The operation path here may be a specific location in the disk, and is typically used for storing files. When the data to be processed is a file, whether the file exists in the operation path or not needs to be inquired based on the check period, if the file does not exist, the waiting is needed, and if the file exists, the processing can be performed.
A batch Task (Task) is composed of one or more batch jobs (Job), each containing one or more batch steps (Step). Each batch Step (Step) comprises specific operations and data, i.e. specific workflow logic processes, whereby one batch task contains multiple data to be processed.
The method comprises the steps of obtaining pre-configured attributes of batch processing tasks to be executed, wherein the pre-configured attributes comprise task numbers, names, task execution states, execution cycles, serial parameters, fragment parameters, executable time periods, task parameters (including specific parameters required by task execution) and the like. Before executing the task, firstly, judging whether the current time period is in the executable time period, and if not, executing a waiting operation.
If the value of the fragmentation parameter is 1, the to-be-processed data can be distributed to a plurality of hosts to be executed when the task is executed; if the value is 0, the data to be processed needs to be distributed to a single host to be executed when the task is executed.
If the value of the serial parameter is 0, the serial parameter indicates that the instance executed each time by the same task does not depend on the state executed by the previous instance; if the value is 1, it indicates that each instance executing the same task must wait for the previous instance to complete (whether success or failure) before executing; if the value is 2, it indicates that each instance executing the same task must wait for the previous instance to execute successfully.
If the data in the batch processing task is in the task executable time period, whether the fragment flag in the attribute is judged to be yes or not is continuously judged, if yes, the data in the batch processing task supports fragment processing, different data can be distributed to different hosts (or called devices) for processing, and if not, the data to be processed of the same batch processing task is distributed to a single host for processing. Assuming that 3 hosts are in a batch processing cluster, the execution of one task needs 3 hosts to be executed simultaneously in a fragment mode, and each host processes more than one third of data, so that the method is mainly used for the conditions of large data volume and relatively fast processing time; for the non-fragmentation mode, all data needs to be allocated to a certain host to be executed.
In the method provided in the foregoing embodiment, a fragmentation flag is set in a task attribute to determine whether to process multiple data in a task in a fragmentation mode. The implementation mode can realize the rapid processing of various batch processing requirements of an organization (such as a bank system), and simplifies the development and operation and maintenance processing of batch processing.
Referring to fig. 2, a schematic flow chart of an alternative task processing method according to an embodiment of the present invention is shown, including the following steps:
s201: determining a batch processing task to be executed, acquiring fragmentation parameters from the attributes of the batch processing task, and judging whether the fragmentation parameters are set to preset values; wherein one batch processing task comprises a plurality of data to be processed;
s202: if the judgment result is yes, calculating the distributed data volume of each device according to the current processor utilization rate and memory utilization rate of each device and the data volume to be processed in the batch processing task by adopting a Hash algorithm, and summarizing the processing result to obtain a total processing result;
s203: if the judgment result is negative, screening out one device with the minimum current load from the multiple devices, and taking the one device as a target device for processing the multiple data together to obtain an execution result;
s204: if the judgment result is negative, determining one or more devices which historically process the batch processing task, counting the historical execution duration of the batch processing task and the utilization rate of a processor when each batch processing task is processed, and further calculating the weight value of each device;
s205: and screening out the device with the largest weight value from the one or more devices, and taking the device as a target device for processing the plurality of data together to obtain an execution result.
In the above embodiment, for step S201, refer to the description of step S101 shown in fig. 1, and no further description is provided herein.
In step S202, it is assumed that the batch processing job to be executed this time includes 20 pieces of data to be processed, and there are 10 hosts in total. For the situation that the task supports the fragment execution, a hash algorithm is adopted, the allocated proportion of each host is calculated according to the current CPU utilization rate and the memory utilization rate of each host, the proportion is multiplied by the data volume to be processed to obtain the allocated data volume of each host, the algorithm ensures that the data is allocated completely, and 10 hosts are substantially evenly divided.
For step S203, for the case that the task does not support the slicing execution, one host with the smallest current load may be screened out from the 10 hosts to process the 20 data together. When the number of tasks to be processed is large, this method may also be adopted, for example, the task a-host 2 and the task B-host 3 each time determine which host processed the previous task, and then determine the host with the smallest current load, and sometimes, a host processes a plurality of tasks.
Dynamic programming algorithms are typically used to solve problems with some optimal nature. In such a problem, there may be many possible solutions, each corresponding to a value, for which it is desirable to find a solution with an optimal value. The basic idea is to decompose the problem to be solved into a plurality of sub-problems, solve the sub-problems first, and then obtain the solution of the original problem from the solutions of the sub-problems.
If there are 3 hosts, if it is feasible to allocate the task a to all 3 hosts, there are 3 feasible solutions. And distributing the tasks to the host with the minimum load by adopting a dynamic programming algorithm, namely, obtaining an optimal solution. And searching the optimal solution every time a task execution instance is newly added. If 10 tasks are to be executed, the most balanced task allocation of 3 hosts is finally achieved according to the mode.
For steps S204 to S205, in addition to the above manner, for the case that the task does not support the slicing execution, the time length of the task history being executed, the devices that have historically processed the task, and the CPU utilization rate of the devices when processing the task may be counted, so as to calculate the weight values of the devices, and then a device with the largest weight value is selected from the devices to process the task.
The method provided by the embodiment adopts different modes to determine the equipment for processing the data for the situations of task fragmentation execution and non-fragmentation execution, thereby realizing the high efficiency of data processing.
Referring to fig. 3, a schematic flow chart of an alternative task processing method according to an embodiment of the present invention is shown, including the following steps:
s301: acquiring a serial parameter from the attribute of the batch processing task, and judging whether the serial parameter is set to be a first preset value or not; the serial parameters correspond to multiple execution instances of the batch processing tasks, and one instance is generated when the batch processing tasks are executed once;
s302: if the judgment result is yes, processing data when the task execution period of the batch processing task is reached;
s303: if the judgment result is negative, acquiring the execution state of the previous batch processing task execution instance, and reprocessing the data under the condition that the execution state is the execution completion;
s304: and if the execution state is not completed when the execution cycle of the batch processing task is reached, another device for processing the plurality of data together is determined again.
In the above embodiment, in steps S301 to S304, if the result of the serial flag determination in the batch job attribute is yes, it indicates that the batch job does not support parallel execution, and otherwise, it indicates that parallel execution is supported. Parallel, meaning that there may be multiple instances of a task at the same time; non-parallel, meaning that a task has only one instance at a time.
Each execution of a task generates an instance and each execution depends on the state results of the previous instance execution. For example, task a is set to execute every 5 minutes and is executed serially, and is executed once at time points 19:55, 20:00, and 20:05, respectively, to generate 3 instances. Task A executes an instance at 19:55, but until 20:00 has not been executed, another device to process task A is re-determined at 20: 00. Similarly, in the 20:05 execution example, since the 20:00 instance has not been executed, another device for processing task A is determined again at 20:05, and if the 20:00 instance has not been executed at 20:10, another device for processing task A is determined again at 20: 10.
For example, it is preset that task a is executed once every 22 pm, but task a of No. 1 has not been executed yet at 22 pm of No. 2. In the serial processing method, the task No. 2 needs to be executed after the task No. 1 is executed, so that the task No. 2 continues to wait even after the current point No. 2 is 22 points. For the parallel processing mode, that is, when the point 22 # 2 is reached, the task # 2 is started to be executed regardless of whether and when the task # 1 is executed.
In the method provided by the above embodiment, for the serial mode and the parallel mode, the device processes data in the task in different manners, especially in the serial manner, the execution state of the previous instance needs to be considered, and if the execution state does not meet the requirement, the processing device is determined again, so that the task is processed in time.
Referring to fig. 4, a schematic flow chart of another alternative task processing method according to the embodiment of the present invention is shown, which includes the following steps:
s401: determining a batch processing task to be executed, acquiring fragmentation parameters from the attributes of the batch processing task, and judging whether the fragmentation parameters are set to preset values; wherein one batch processing task comprises a plurality of data to be processed;
s402: if the judgment result is yes, determining a plurality of devices for processing the plurality of data, respectively distributing different data to corresponding devices for processing, summarizing the processing result, and obtaining an execution result;
s403: if the judgment result is negative, determining one device which processes the plurality of data together, and distributing the plurality of data together to the one device for processing to obtain an execution result;
s404: monitoring an execution state in the process of executing the batch processing task, and if the execution state is abnormal, recording abnormal data, operating equipment and an abnormal reason to generate a task execution abnormal log;
s405: responding to the opening of the task execution exception log, and positioning an exception execution step according to the exception data and an exception reason; wherein a batch job comprises a plurality of execution steps.

The task parameters are packaged in the first stage, when the task is executed in the second stage, the task parameters used in each batch processing step may be different, each step also has its own parameters, and then the required parameters and the parameters of the step itself need to be taken out from the task parameters and then assembled.
According to the method provided by the embodiment, the enhanced event monitor is utilized, error data can be recorded in the log file in the task execution process, the error reason is recorded, the specific problems can be conveniently and rapidly located according to the reason and the data, and the operation monitoring and operation and maintenance processing of batch processing tasks are improved.
