Create Job

This section provides detailed information on the Jobs to make your data process faster.

Jobs are used for ingesting and transferring data from separate sources. The user can transform, unify, and cleanse data to make it suitable for analytics and business reporting without using the Kafka topic which makes the entire flow much faster.

Check out the given demonstration to understand how to create and activate a job.

Creating and activating a job.

Creating a new Job

• Navigate to the Data Pipeline homepage.

• Click on the Create Job icon.

• The New Job dialog box appears redirecting the user to create a new Job.

• Enter a name for the new Job.

• Describe the Job(Optional).

• Job Baseinfo: In this field, there are two options:

  • Spark Job

  • PySpark Job

• Trigger By: There are 2 options for triggering a job on success or failure of a job:

  • Success Job: On successful execution of the selected job the current job will be triggered.

  • Failure Job: On failure of the selected job the current job will be triggered.

• Is Scheduled?

  • A job can be scheduled for a particular timestamp. Every time at the same timestamp the job will be triggered.

  • Job must be scheduled according to UTC.

• Concurrency Policy: Concurrency policy schedulers are responsible for managing the execution and scheduling of concurrent tasks or threads in a system. They determine how resources are allocated and utilized among the competing tasks. Different scheduling policies exist to control the order, priority, and allocation of resources for concurrent tasks.

Please Note: Concurrency Policy will appear only when "Is Scheduled" is enabled.

• There are 3 Concurrency Policy available:

  1. Allow: If a job is scheduled for a specific time and the first process is not completed before the next scheduled time, the next task will run in parallel with the previous tasks.

     

     Allow concurrency policy

  2. Forbid: If a job is scheduled for a specific time and the first process is not completed before the next scheduled time, the next task will wait until all the previous tasks are completed.

     

     Forbid concurrency policy

  3. Replace: If a job is scheduled for a specific time and the first process is not completed before the next scheduled time, the previous task will be terminated and the new task will start processing.

     

     Replace concurrency policy

• Spark Configuration

  • Select a resource allocation option using the radio button. The given choices are:

    • Low

    • Medium
