David Johnson updated USERGRID-1007:
------------------------------------
Description:
How will a cache help improve performance?
* Reduce load on Tomcat, ES and C* caused by permissons calculation.
Do we need a distributed cache?
* YES: Todd says we tried non-distributed cache (w/EhCache) and the caching was
not effective (bad hit/mss ratio).
Implementation ideas:
* Use Cassandra column family implementation
* Use Hazelcast cache
* Use EhCache configured for distributed operation
How much should we expect performance to improve? How can we test this?
* JUnit + metrics collection in our cache implementation

Need to test this
How many calls to C* and ES will cache prevent per request?
Need to test this
How can we test this?
