Explanation
When you get an MbGlobalMap object, you can specify how long the data remains in the global cache before it is removed automatically. This time is known as the time to live and is counted from when that map entry is last updated. By default, the time to live is set to zero so that the data is never removed. To set a specific time to live, create a session policy, which you can reference from the MbGlobalMap object.
