Queries Fail Faster with Keeper Connection Retry Issues

Official CH changelog text
Queries will fail faster if a new Keeper connection cannot be established during retries. #69148 (Raúl Marín).
Queries will fail faster if a new Keeper connection cannot be established during retries.

Why it matters

This feature improves query reliability and responsiveness by reducing the wait time when ClickHouse is unable to establish a new connection to the Keeper service after multiple retries. It prevents long delays during connection attempts, allowing queries to fail quickly if the Keeper service is unreachable.

How to use it

This behavior is enabled automatically with the update; no additional user configuration is required to benefit from faster failure upon Keeper connection issues.
