Execution Groups FAQS

1. What is an Execution Group?

• An execution group is a collection of objects, such as source and target groups, that are executed in parallel within the same execution unit. It helps to manage tasks that can be executed concurrently for better performance.

2. How are Execution Groups displayed?

• Execution groups are represented by yellow boxes in the interface. These yellow boxes visually indicate the grouping of execution units that will run simultaneously.

3. What does it mean for tasks to be executed in parallel within an Execution Group?

• When tasks are executed in parallel, multiple objects, such as source and target groups, within the same execution group are processed at the same time, instead of sequentially. This improves processing efficiency and reduces overall execution time.

4. What are Source Groups and Target Groups in an Execution Group?

• Source Groups: These are the groups containing the data sources, like databases or files, that supply the data for processing.
• Target Groups: These are the groups that define where the processed data will be sent, such as databases or file systems.

5. Why should I use Execution Groups?

• Execution groups are useful because they enable parallel processing, which speeds up data handling. By executing source and target groups concurrently, you can optimize resource usage and reduce the overall time needed to process data.

6. Can I modify an Execution Group after it’s created?

• Yes, you can adjust or reconfigure execution groups. Depending on your requirements, you can modify which tasks are grouped together, ensuring that execution is optimized based on the nature of the tasks.

7. How do Execution Groups improve performance?

• Execution groups enhance performance by allowing multiple tasks to run at the same time, reducing idle times and speeding up the data processing flow.

8. Are Execution Groups always executed in parallel?

• Yes, the tasks inside an execution group are executed in parallel by default. However, you may need to adjust configurations if you need specific tasks to execute sequentially.

9. Can I have multiple Execution Groups in a single process?

• Yes, you can have multiple execution groups in a single process. They can be configured independently to run in parallel, based on how you need to manage your source and target groups.

10. Can Execution Groups be used for all types of data tasks?

• Execution groups are especially effective for tasks that can be run concurrently without dependency issues. For tasks that require sequential execution or depend on the completion of others, they may need to be handled outside of an execution group or with different settings.
