Abstract: Techniques are provided for creating, organizing, and maintaining a sharded database. A sharded database can be created using user-defined sharding, system-managed sharding, or composite sharding. The sharded database is implemented with relational database techniques. The techniques described provide improvements to load distribution, organization, query processing, and schema propagation in a sharded database.
