 With this improvement you have maximum flexibility: you can define consistent default settings for the entire cluster, but still tailor individual backup or restore operations as needed. This way you can optimize performance, troubleshoot, or customize specific scenarios without affecting the global configuration.
 
+### Increased timeouts for read, write and clone operations inside MySQL cluster
+
+To improve reliability of clone operations in asynchronous MySQL clusters, especially when transferring large datasets (2GB and more), we've increased the default timeouts for read,write and clone operations to 3600 seconds. This change helps prevent premature failures caused by network delays or slow disk I/O during large data transfers.
+
+You can fine-tune the timeout for cloning in your custom resource (CR) using the `BOOTSTRAP_CLONE_TIMEOUT` environment variable:
+
+```yaml
+spec:
+  mysql:
+    env:
+      - name: BOOTSTRAP_CLONE_TIMEOUT
+        value: "3600"
+```
+
+This update ensures smoother provisioning and bootstrapping of new database nodes, especially in environments with large datasets or variable network conditions.
