| |
| `IgniteCountDownLatch` provides functionality that is similar to that of `java.util.concurrent.CountDownLatch` and allows you to synchronize operations accross cluster nodes. |
| |
| A distributed CountDownLatch can be created as follows: |
| |
| [source, java] |
| ---- |
| include::{javaFile}[tags=count-down-latch, indent=0] |
| ---- |
| |
| |
| After the above code is executed, all nodes in the specified cache will be able to synchronize on the latch named `latchName`. |
| Below is a code example of such synchronization: |
| |
| |
| [source, java] |
