Vector Clock Explosion in Eventually Consistent Key-Value Stores : Retry, Timeout, and Circuit-Breaker Composition Failures

RustRocksDBTokioQUIC

Problem Breakdown

The defect class here is composition: individually sensible timeouts, retries, and circuit breakers interact multiplicatively when layered across a call graph. Every concurrent write adds an actor entry to the object's vector clock; high-fanout clients writing the same hot keys force clocks to grow with the writer coun…
