DB Instance Specifications¶
The format of the specification code is: {spec code}{instance mode}.
spec code can be obtained from Table 1.
instance mode can be any of the following:
For single DB instances, the value is null. Example specification code: rds.mysql.s3.large.2
For primary/standby DB instances, the value is .ha. Example specification code: rds.mysql.s3.large.2.ha
For read replicas, the value is .rr. Example specification code: rds.mysql.s3.large.2.rr
For cluster instances, the value is .ha. Example specification code: rds.mssql.s3.large.ha
Constraints¶
Only DB instances running Microsoft SQL Server 2017 EE support the creation of read replicas. Microsoft SQL Server 2017 EE does not support the creation of single DB instances.
