Write amplification and the RUM conjecture
The RUM conjecture
Every storage engine optimizes at most two of three overheads:
| Overhead | Definition |
|---|---|
| Read amplification | Bytes read per logical read |
| Update amplification | Bytes written per logical write |
| Memory/space amplification | Bytes stored per logical byte |
No engine minimizes all three. Every engine is a position on this triangle, and every tuning knob moves along an edge. A claim that one engine is strictly better means a workload was chosen where the sacrificed dimension does not matter.
