Table 1 lists the DB engines and versions supported by RDS.
For new applications, you are advised to use the latest version of the DB engine. The following uses MySQL 5.7.23 as an example. When you create a DB instance, you can only select the major DB engine version (MySQL 5.7). The minor version (5.7.23) is automatically selected by the system. After the DB instance is created, you can view the minor version in the DB Engine Version column on the Instance Management page.
