Description: A node executor in Jenkins is responsible for executing jobs on a specific node. In the context of Jenkins, which is a continuous integration and continuous delivery (CI/CD) tool, executors are key components that allow the execution of build, test, and deployment tasks. Each node in Jenkins can have one or more executors, enabling multiple jobs to run simultaneously on that node. This is particularly useful in development environments where high availability and efficiency in task execution are required. Executors can be configured to utilize different system resources, such as CPU and memory, and can be assigned to specific jobs based on project needs. The ability to scale horizontally by adding more nodes and executors allows development teams to handle larger and more complex workloads, thereby optimizing the software development and delivery workflow.
