pip install redis==7.1.0

Production note: Most teams hit this during upgrades or environment changes. Roll out with a canary and smoke critical endpoints (health, OpenAPI/docs) before 100%.

Why This Fix Works in Production

  • Trigger: There is so much logs in `cluster` module that I would not want it to show up in my application logs. Is there a reason to leave these logs in this module?…
  • Mechanism: Verbose logging in the cluster module adds unnecessary overhead and clutter to application logs
  • Why the fix works: Removes verbose logging from the cluster module in redis-py, addressing concerns raised in issue #2227. (first fixed release: 7.1.0).
Production impact:
  • If left unfixed, the same config can fail only in production (env differences), causing startup failures or partial feature outages.

Why This Breaks in Prod

  • Shows up under Python 3.8.10 in real deployments (not just unit tests).
  • Verbose logging in the cluster module adds unnecessary overhead and clutter to application logs
  • Production symptom (often without a traceback): There is so much logs in `cluster` module that I would not want it to show up in my application logs. Is there a reason to leave these logs in this module? Instead, couldn't we just raise exception and let the user handle them as he wishes?
