The Basic Use of RDS - Part 4: Introduction To ApsaraDB RDS MySQL Series
In this video tutorial, we will introduce the three types of ApsaraDB RDS for MySQL series, including Basic Edition (also known as single instance), High-Availability Edition with two nodes and Enterprise Edition with three nodes. And the engine versions support from MySQL 5.5 to MySQL 8.0.
🌟 Basic Edition
Only one node, RO not available
🌟 HA Edition
Primary node for R/W;
Secondary node for DR only, can not be used for read workload;
Add RO for read.
🌟 Enterprise Edition
Similar to HA Edition, but with an extra assurance because of log node.
Quick update: the data synchronization to RO nodes and logger node is from secondary node instead. This design enables the primary node to take full use of available resources to support business.
