> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Reporter: Abhay Kulkarni

>
> When the number of policies (and/or tagged resources) is large, the data
> structures used by Ranger as indexes for policies (and/or tagged resources)
> may need a very large heap memory because they are optimized for fast lookup.
> It is desirable to be able to configure Ranger to have these structures
> optimized for space in order to keep the heap requirements within acceptable
> limit at the cost of somewhat slower lookup.
