1. What are Execution Units?
- Execution Units are represented by blue boxes within the yellow execution groups in the diagram. These units represent specific tasks or operations that can be executed within the execution group.
2. Placement within Execution Groups:
- Execution units are part of the execution groups (which are yellow boxes). They exist inside the execution group and are responsible for specific tasks like data extraction or loading.
3. Physical Data Server Location:
- All execution units within a single execution group are located on the same physical data server. This ensures that they share the same server resources and can be executed in parallel without communication delays between servers.
4. Different Structures in Execution Units:
- Execution units within the same execution group may represent different data structures or tasks. These could be distinct operations, such as extracting data from different tables, applying transformations, or loading into different targets.
5. Parallel Execution of Tasks:
- Since all execution units are on the same physical data server, they can be executed in parallel, which allows for simultaneous processing of different tasks or structures. This helps optimize performance and reduce the overall time needed for execution.
6. Visual Representation:
- In the diagram, execution units are represented as blue boxes within the yellow execution group. Each execution unit handles a different task or structure, and they work together as part of the larger execution group.
7. Efficient Resource Usage:
- Because execution units are all on the same physical server, they can leverage the same server resources, which maximizes efficiency and minimizes delays related to network or inter-server communication.
8. Managing Execution Units:
- Execution units can be managed within the execution group to ensure that tasks are distributed effectively, resources are utilized efficiently, and parallel execution is optimized for faster data processing.
