Method Summary

Modifier and Type	Method	Description
void	addTaskToRefreshPersistentCache(long spaceId, int requestedLimit)	Adds a new task for refreshing cache records in the queue If there is another cache record in the queue, we should not add a new one We need to update the existing one (if required)
