# Comprehensive ManagedJob Example
# This example demonstrates all capabilities of the jobs-manager-operator
#
# Workflow Overview:
# 1. setup-group: Creates initial configuration (runs first, sequential)
# 2. parallel-workers: Multiple parallel jobs that process data
# 3. aggregation-group: Depends on parallel-workers completion
# 4. notification-group: Final notification job
