Abstract: Techniques described herein create a sharding environment from existing independent databases, use the sharding environment to issue cross shard queries, create “on all shards” new objects, and create and “on all shards” new users that will have permission to access the data across all database shards.

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.

Abstract: Embodiments include a method, apparatus and computer program product for providing instructions from a database client to a database server. The method includes the steps of receiving from a database a representation of a first instruction and an associated identifier. The representation of the first instruction and the associated identifier are stored in a cache. A second instruction, from an application, is matched with the representation of the first instruction stored in the cache. The associated identifier is retrieved from the cache based on the matching and the associated identifier is sent to the database server. Upon receipt of the associated identifier, the database server executes the first instruction.
