2) external (External destination): Indicates that the job executes outside the database
It is important to note that if the job is performed remotely, the scheduler agent must be installed on the remote host.
File Watcher (document keeper)
The file keeper defines the destination, file name, and so on, triggering an event once a qualifying file arrives, starting the job

Here is a brief talk about the general principles, details and exception handling after the opportunity to speak alone
First of all, to break the principle of local localstorage, th

The latter is more appropriate.House-keeping-sleep-time:house keeper retains the maximum amount of time a thread is asleep, house keeper's job is to check the status of each connection and determine whether it needs to be destroyed or created.House-keeping-test-sql: If an idle database connection is found. House
occurs, his exception information is compared to this fragment of information. If present in the fragment, the exception will be considered a fatal error (Fatal SQL exception). In this case, the database connection will be discarded. No matter what happens, this exception will be re-thrown to provide to the consumer. It is best for users to configure a different exception to throw.Fatal-sql-exception-wrapper-class: As mentioned above, you'd better configure a different exception to re-throw. Wi

There is no automatic master election mechanism, but I think it is better to put it outside.
Async/sync ReplicationLedisdb is a synchronous replication that supports strong consistency, and if this mode is configured, Master waits for the slave to complete the log before committing the update, so that we can guarantee that when Master is in the machine, There must be a slave with the same data as master. However, in practice, because of the network environment or slave, master can not
write an XML configuration mapping file to tell the framework if and when it is ORM. Also, once the object model has changed, the mapping file is modified. These have greatly increased the learning curve and workload of the developer and are prone to error. The idea of the Bean keeper is simple to do, and it simplifies these operations as much as possible.
The Bean Keeper is an Open-source software based
