| aoqi@0 | 31 | * This class has HA information |
| aoqi@0 | 32 | * <p> |
| aoqi@0 | 33 | * |
| aoqi@0 | 34 | * This would help a loadbalancer to put the request(in case of a fail-over) |
| aoqi@0 | 35 | * on a replica instance that has all the related data. Even if there is no |
| aoqi@0 | 36 | * loadbalancer, a backing store could locate the information by directly |
| aoqi@0 | 37 | * going to the correct replica instance. This would also help any part of |
| aoqi@0 | 38 | * the runtime to know about failover case(and in-turn may invalidate |
| aoqi@0 | 39 | * local caches). |
| aoqi@0 | 40 | * |
| aoqi@0 | 41 | * <p> |
| aoqi@0 | 42 | * To achieve this functionality, it carries two pieces of information: |
| aoqi@0 | 43 | * <ol> |
| aoqi@0 | 44 | * <li>key - Related {@link com.sun.org.glassfish.ha.store.api.BackingStore} keys can |
| aoqi@0 | 45 | * use this info for their HashableKey impl. First store creates this object, |
| aoqi@0 | 46 | * and subsequent related stores use the same key. |
| aoqi@0 | 47 | * <li>replicaInstance - where the related info is replicated |
| aoqi@0 | 48 | * </ol> |
| aoqi@0 | 49 | * |
| aoqi@0 | 50 | * <p> |
| aoqi@0 | 51 | * This can be accessed from {@link Packet} using {@link Packet#HA_INFO} |
| aoqi@0 | 52 | * property by the runtime. This object is created typically |
| aoqi@0 | 53 | * <ul> |
| aoqi@0 | 54 | * <li> When a store happens for the first time |
| aoqi@0 | 55 | * <li> A subsequent inbound transport creates from cookies |
| aoqi@0 | 56 | * <li> A fail-over request stores the data to a different replica |
| aoqi@0 | 57 | * </ul> |
