+# Disable Maintenance Notifications Example
+
+This example demonstrates how to use the go-redis client with maintenance notifications **disabled**.
+
+## What are Maintenance Notifications?
+
+Maintenance notifications are a Redis Cloud feature that allows the server to notify clients about:
+- Planned maintenance events
+- Failover operations
+- Node migrations
+- Cluster topology changes
+
+The go-redis client supports three modes:
+- **`ModeDisabled`**: Client doesn't send `CLIENT MAINT_NOTIFICATIONS ON` command
+- **`ModeEnabled`**: Client forcefully sends the command, interrupts connection on error
+- **`ModeAuto`** (default): Client tries to send the command, disables feature on error
+
+## When to Disable Maintenance Notifications
+
+You should disable maintenance notifications when:
+
+1. **Connecting to non-Redis Cloud / Redis Enterprise instances** - Standard Redis servers don't support this feature
+2. **You want to handle failovers manually** - Your application has custom failover logic
+3. **Minimizing client-side overhead** - You want the simplest possible client behavior
+4. **The Redis server doesn't support the feature** - Older Redis versions or forks
+
+## Usage
+
+### Basic Example
+
+```go
+import (
+    "github.com/redis/go-redis/v9"
+    "github.com/redis/go-redis/v9/maintnotifications"
+)
+
+rdb := redis.NewClient(&redis.Options{
+    Addr: "localhost:6379",
+
+    // Explicitly disable maintenance notifications
+    MaintNotificationsConfig: &maintnotifications.Config{
+        Mode: maintnotifications.ModeDisabled,
+    },
+})
+defer rdb.Close()
+```
+
+### Cluster Client Example
+
+```go
+rdbCluster := redis.NewClusterClient(&redis.ClusterOptions{
+    Addrs: []string{"localhost:7000", "localhost:7001", "localhost:7002"},
+
+    // Disable maintenance notifications for cluster
+    MaintNotificationsConfig: &maintnotifications.Config{
+        Mode: maintnotifications.ModeDisabled,
+    },
+})
+defer rdbCluster.Close()
+```
+
+### Default Behavior (ModeAuto)
+
+If you don't specify `MaintNotifications`, the client defaults to `ModeAuto`:
+
+```go
+// This uses ModeAuto by default
+rdb := redis.NewClient(&redis.Options{
+    Addr: "localhost:6379",
+    // MaintNotificationsConfig: nil means ModeAuto
+})
+```
+
+With `ModeAuto`, the client will:
+1. Try to enable maintenance notifications
+2. If the server doesn't support it, silently disable the feature
+3. Continue normal operation
+
+## Running the Example
+
+1. Start a Redis server:
+   ```bash
+   redis-server --port 6379
+   ```
+
+2. Run the example:
+   ```bash
+   go run main.go
+   ```
+
+## Expected Output
+
+```
+=== Example 1: Explicitly Disabled ===
+✓ Connected successfully (maintenance notifications disabled)
+✓ SET operation successful
+✓ GET operation successful: value1
+
+=== Example 2: Default Behavior (ModeAuto) ===
+✓ Connected successfully (maintenance notifications auto-enabled)
+
+=== Example 3: Cluster Client with Disabled Notifications ===
+Cluster not available (expected): ...
+
+=== Example 4: Performance Comparison ===
+✓ 1000 SET operations (disabled): 45ms
+✓ 1000 SET operations (auto): 46ms
+
+=== Cleanup ===
+✓ Database flushed
+
+=== Summary ===
+Maintenance notifications can be disabled by setting:
+  MaintNotificationsConfig: &maintnotifications.Config{
+    Mode: maintnotifications.ModeDisabled,
+  }
+
+This is useful when:
+  - Connecting to non-Redis Cloud instances
+  - You want to handle failovers manually
+  - You want to minimize client-side overhead
+  - The Redis server doesn't support CLIENT MAINT_NOTIFICATIONS
+```
+
+## Performance Impact
+
+Disabling maintenance notifications has minimal performance impact. The main differences are:
+
+1. **Connection Setup**: One less command (`CLIENT MAINT_NOTIFICATIONS ON`) during connection initialization
+2. **Runtime Overhead**: No background processing of maintenance notifications
+3. **Memory Usage**: Slightly lower memory footprint (no notification handlers)
+
+In most cases, the performance difference is negligible (< 1%).
