Description

Design an extreme stress test to verify system stability under upgrade/downgrade scenario. The core scenario involves the system handling an extreme load of 200k tables and 10k changefeeds while undergoing frequent version rollbacks (e.g., continuous A->B->A version toggle cycles).

  1. Use AI to generate 200k tables with random schemas and apply continuous read/write workload.

  2. Trigger consecutive upgrade/downgrade cycles while the full load is running.

Research direction

No files, tests, or entry points are named. Start by locating existing stress tests and upgrade/downgrade harnesses, then determine how they generate tables, changefeeds, and workload. Done means a repeatable test covering 200k tables, 10k changefeeds, continuous reads and writes, and A→B→A cycles with stability results.
