Will the slave node of ApsaraDB for Redis be updated with its master node?

Last Updated: Jun 09, 2018

Updates on the master node are automatically replicated to the associated slave node. However, the Redis asynchronous replication mechanism may cause updates for the slave node to lag behind the master node. This may happen because the I/O write speed on the master node exceeds the synchronization speed on the slave node, or network latency exists between the master and slave nodes. As a result, the data replication from the master node to the slave node may experience latency or the data on the master and slave nodes may be inconsistent.
