Walkthrough

The environment schema in the application was updated to make the RUN_REPLICATION_KEEP_ALIVE_IDLE_SOCKET_TTL_MS variable optional and removed its default value of 9000. This alters how the environment variable is validated and handled within the application.

Poem

A tweak to the schema, a gentle hop,
No more defaults—let the numbers stop!
Optional now, the field may rest,
The code adapts, it does its best.
With every change, we leap ahead,
A rabbit’s cheer for code well-bred! 🐇

773-773: Improvement to prevent socket hangup errors.

Removing the default value of 9000ms and making this environment variable optional allows the system to use more conservative default socket TTL values. The previous aggressive 9-second TTL setting could lead to premature socket disconnections, especially during periods of network latency or when ClickHouse is under load.
