all-master-shards

| default_shards_placement | dense
sparse | Default shards_placement for a newly created databases |

| <span class="break-all">failure_detection_sensitivity</span> | high
low | Predefined thresholds and timeouts for failure detection (previously known as <span class="break-all">watchdog_profile</span>)
• high (previously local-network) – high failure detection sensitivity, lower thresholds, faster failure detection and failover
• low (previously cloud) – low failure detection sensitivity, higher tolerance for latency variance (also called network jitter) |
| hide_user_data_from_log | boolean (default: false) | Set to true to enable the <span class="break-all">hide-user-data-from-log</span> Redis configuration setting, which avoids logging user data |
| <span class="break-all">login_lockout_counter_reset_after</span> | integer | Number of seconds that must elapse between failed sign in attempts before the lockout counter is reset to 0. |
