It is also possible to synchronize any arbitrary block of code on any given object: for more details, see the section on the Java synchronized keyword. Explicit locksThe built-in synchronization mechanism has some limitations. For example, a thread will potentially block forever waiting to acquire...
Java Synchronization will throw NullPointerException if object used in java synchronized block is null. For example, in above code sample if lock is initialized as null, the synchronized (lock) will throw NullPointerException. Synchronized methods in Java put a performance cost on your application....
in the source. In this case, you can upgrade the specifications of the resource group. If you modify the configuration of the synchronization task, you can change the number of source databases and tables. For example, if the original synchronization task is used to synchronize data from a ...
So there is a need to synchronize the action of multiple threads and make sure that only one thread can access the resource at a given point in time. This is implemented using a concept called monitors. Each object in Java is associated with a monitor, which a thread can lock or unlock...
In this example, the addName method needs to synchronize changes to lastName and nameCount, but also needs to avoid synchronizing invocations of other objects' methods. (Invoking other objects' methods from synchronized code can create problems that are described in the section on Liveness.) With...
For example, can I use a function supported by a MaxCompute data source to aggregate Fields a and b in a MaxCompute table as a primary key for synchronizing data to Lindorm?Feedback Previous: Configure an IP address whitelistNext: Real-time synchronization...
