Memory Saving Mode
All activity output variables in a running process instance are stored in a memory, and hence consume memory. Memory saving mode allows memory used by an activity output variable to be released when the value of the variable is no longer needed.
In a memory saving mode, as each activity is executed, the list of activity output variables is continuously evaluated to determine if subsequent activities in the process refer to the specific activity output variable. If no activities refer to the activity output variable, the memory used by it is released.
Memory saving mode can reduce the memory used by actively running process instances, as well as potentially improve the performance of checkpoints. By default, memory saving mode is disabled. This property, when set to true, enables usage of memory saving mode, which frees activity output variables once they are no longer needed. The default value is false.
Memory saving is enabled at design-time and run-time both.
