6.6. The Replication Queue
6.6.1. Replication Queue
Link kopierenLink in die Zwischenablage kopiert!
In replication mode, JBoss Data Grid uses a replication queue to replicate changes across nodes based on the following:
- Previously set intervals.
- The queue size exceeding the number of elements.
- A combination of previously set intervals and the queue size exceeding the number of elements.
The replication queue ensures that during replication, cache operations are transmitted in batches instead of individually. As a result, a lower number of replication messages are transmitted and fewer envelopes are used, resulting in improved JBoss Data Grid performance.
A replication queue is used in conjunction with asynchronous mode.
