  • log_min_seconds_to_retain and follower_unavailable_considered_failed_sec
  • leader_lease_duration_ms and raft_heartbeat_interval_ms

Contributor guide

Research direction
Identify the gflag definitions in the docdb codebase and understand the current validation mechanism. Then, for each pair of logically connected flags listed in the issue, implement validators that ensure consistency (e.g., leader lease duration ms >= raft heartbeat interval ms).
