>             Project: Tephra
>          Issue Type: Bug
>          Components: core, manager

>             Fix For: 0.13.0-incubating
>
>
> Suppose an application regularly creates and deletes tables (for example, 
> temporary tables). In such a scenario, there will always be such a temporary 
> table when pruning runs, and its regions will be recorded for that time. 
> However, the region will be deleted before it ever compacts or flushes, and 
> it will never record prune information. Because all prune times have such 
> regions, there will never be a set of transactional regions that all have 
> prune info, and pruning will never happen. 
> The fix is to exclude deleted tables from the list of regions at each time. 
> This is all regions of deleted tables (tables that do not exist any more), 
> not deleted regions: a region may disappear due to a split and its data will 
> be in new regions.
