+    Configuration for retry logic with exponential backoff.

+    This configuration controls how connection attempts are retried when they fail.

+        max_retries: Maximum number of retry attempts before giving up.
+                     Default: 3 attempts

+                      Default: 0.1 seconds (100ms)
+        max_delay: Maximum delay cap in seconds to prevent excessive wait times.
+                  Default: 30.0 seconds
+        backoff_multiplier: Multiplier for exponential backoff (each retry multiplies
+                           the delay by this factor). Default: 2.0 (doubles each time)
+        jitter_factor: Random jitter factor (0.0-1.0) to add randomness to delays
+                      and prevent synchronized retries. Default: 0.1 (10% jitter)
