Many out of one: Dynamically Replicated Databases
Dynamically distributed databases
- Single machine can’t manage over a terabyte of disk cache
- No good way to statically partition the database
Dynamically varying database access paths
- As load increases, add more copies
- Copies accessed in parallel
- As load decreases, remove copies to free up disk space
Objectivity catalog independence
- Copies managed outside of Objectivity
- Minimizes impact on administration
