| <div class="block">A zookeeper that can handle 'recoverable' errors. |
| To handle recoverable errors, developers need to realize that there are two |
| classes of requests: idempotent and non-idempotent requests. Read requests |
| and unconditional sets and deletes are examples of idempotent requests, they |
| can be reissued with the same results. |
| (Although, the delete may throw a NoNodeException on reissue its effect on |
| the ZooKeeper state is the same.) Non-idempotent requests need special |
| handling, application and library writers need to keep in mind that they may |
| need to encode information in the data or name of znodes to detect |
| retries. A simple example is a create that uses a sequence flag. |
| If a process issues a create("/x-", ..., SEQUENCE) and gets a connection |
| loss exception, that process will reissue another |
| create("/x-", ..., SEQUENCE) and get back x-111. When the process does a |
| getChildren("/"), it sees x-1,x-30,x-109,x-110,x-111, now it could be |
| that x-109 was the result of the previous create, so the process actually |
| owns both x-109 and x-111. An easy way around this is to use "x-process id-" |
| when doing the create. If the process is using an id of 352, before reissuing |
| the create it will do a getChildren("/") and see "x-222-1", "x-542-30", |
| "x-352-109", x-333-110". The process will know that the original create |
| succeeded an the znode it created is "x-352-109".</div> |
