For an example of a sharding solution using an existing framework, see Using an Example of Sharding with Hibernate.īecause of the extensibility limitations of striped storage attached to Windows Server, Amazon RDS doesn’t currently support increasing storage on a SQL Server DB instance. If you do choose to use an existing framework, it must not require any components to be installed on the same server as the DB instance.

You can either use an existing framework like Hibernate Shards or write custom code to enable this. This approach requires data-dependent routing logic in applications that connect to the sharded system, so that data gets queried from and written to the appropriate shard. If you have a scenario that requires a larger amount of storage, it is possible to use sharding across multiple DB instances to get around this limit. The maximum storage size for a SQL Server DB instance is 4 TB for the Enterprise, Standard, and Web editions, and 300 GB for the Express edition. The minimum storage size for a SQL Server DB instance is 20 GB for the Express and Web Editions, and 200 GB for the Standard and Enterprise Editions. You can’t rename databases on a DB instance in a SQL Server Multi-AZ with Mirroring deployment. Some ports are reserved for Amazon RDS use and you can’t use them when you create a DB instance.Īmazon RDS for SQL Server does not support importing data into the msdb database.
The Microsoft system databases, such as master and model, don’t count toward this limit. You can create up to 30 databases on each of your DB instances running Microsoft SQL Server. The Amazon RDS implementation of Microsoft SQL Server on a DB instance have some limitations you should be aware of: Limits for Microsoft SQL Server DB Instances
