Meaning
Spatial boundaries define the physical or logical volume that a process is permitted to occupy during operation. A volumetric boundary limits the amount of space, memory or data that a system can consume before it triggers a safety protocol. This constraint is necessary for preventing one process from starving others of the resources they need to function.
It serves as a hard cap on the size of the operation within a shared environment.
Capacity Limit
Total amount of room available for a process determines the maximum scale it can reach. When the capacity limit is approached, the system may start to slow down as it struggles to fit new tasks into the remaining space. This threshold is often set well below the absolute physical limit to provide a safety buffer.
Monitoring the proximity to this limit is a key part of capacity planning for any growing system. If the limit is hit, the system must either stop or delete old data to make room for the new.
Spatial Constraint
Restrictions on the physical or logical layout of a system prevent it from becoming too complex to manage. Such a spatial constraint forces the design to remain efficient and focused.
Density Threshold
Maximum amount of work that can be packed into a single unit of volume defines the intensity of the operation. The density threshold prevents the system from overheating or crashing due to overcrowding.
