| /** |
| * This class has HA information |
| * <p> |
| * |
| * This would help a loadbalancer to put the request(in case of a fail-over) |
| * on a replica instance that has all the related data. Even if there is no |
| * loadbalancer, a backing store could locate the information by directly |
| * going to the correct replica instance. This would also help any part of |
| * the runtime to know about failover case(and in-turn may invalidate |
| * local caches). |
| * |
| * <p> |
| * To achieve this functionality, it carries two pieces of information: |
| * <ol> |
| * <li>key - Related {@link com.sun.org.glassfish.ha.store.api.BackingStore} keys can |
| * use this info for their HashableKey impl. First store creates this object, |
| * and subsequent related stores use the same key. |
| * <li>replicaInstance - where the related info is replicated |
| * </ol> |
| * |
| * <p> |
| * This can be accessed from {@link Packet} using {@link Packet#HA_INFO} |
| * property by the runtime. This object is created typically |
| * <ul> |
| * <li> When a store happens for the first time |
| * <li> A subsequent inbound transport creates from cookies |
| * <li> A fail-over request stores the data to a different replica |
| * </ul> |
