| * The HA QuickStart Example. |
| * |
| * This example takes the following steps: |
| * |
| * 1. Connect to a Geode Distributed System which has two cache servers. |
| * 2. Create a Geode Cache with redundancy level = 1. |
| * 3. Get the example generic Region from the Cache. |
| * 4. Call registerKeys() on the Region. |
| * 5. Call registerRegex() on the Region. |
| * 6. Put two keys in the Region. |
| * 7. Verify that the keys are destroyed via expiration in server. |
| * 8. Close the Cache. |
