+        Eager loading or lazy loading is a design pattern commonly used in computer programming which
+        will initialize an object upon creation or load on-demand. In carbon, lazy loading is used to
+        load tenant when a request is received only. Similarly Eager loading is used to enable load
+        existing tenants after carbon server starts up. Using this feature, you will be able to include
+        or exclude tenants which are to be loaded when server startup.
+
+        We can enable only one LoadingPolicy at a given time.
+
+        1. Tenant Lazy Loading
+           This is the default behaviour and enabled by default. With this policy, tenants are not loaded at
+           server startup, but loaded based on-demand (i.e when a request is received for a tenant).
+           The default tenant idle time is 30 minutes.
+
+        2. Tenant Eager Loading
+           This is by default not enabled. It can be be enabled by un-commenting the <EagerLoading> section.
+           The eager loading configurations supported are as below. These configurations can be given as the
+           value for <Include> element with eager loading.
+                (i)Load all tenants when server startup             -   *
