    Abstract: In accordance with an embodiment, the system enables access to a sharded database using a cache and a shard topology. A shard-aware client application connecting to a sharded database can use a connection pool (e.g., a Universal Connection Pool, UCP), to store or access connections to different shards or chunks of the sharded database within a shared pool. As new connections are created, a shard topology layer can be built at the database driver layer, which learns and caches shard key ranges to locations of shards. The shard topology layer enables subsequent connection requests from a client application to use a fast key path access to the appropriate shard or chunk.

    Abstract translation: 根据实施例，该系统使得能够使用高速缓存和分片拓扑来访问分片数据库。 连接到分片数据库的分片识别客户端应用程序可以使用连接池（例如，通用连接池，UCP）来存储或访问到共享池内的分片数据库的不同碎片或块的连接。 当创建新连接时，可以在数据库驱动程序层构建分片拓扑图层，数据库驱动程序层可以将分片键范围学习并缓存到分片的位置。 分片拓扑层使来自客户端应用程序的后续连接请求能够使用快速键路径访问适当的分片或块。

    Abstract: In accordance with an embodiment, described herein are systems and methods for providing direct access to a sharded database. A shard director provides access by software client applications to database shards. A connection pool (e.g., a Universal Connection Pool, UCP) and database driver (e.g., a Java Database Connectivity, JDBC, component) can be configured to allow a client application to provide a shard key, either during connection checkout or at a later time; recognize shard keys specified by the client application; and enable connection by the client application to a particular shard or chunk. The approach enables efficient re-use of connection resources, and faster access to appropriate shards.
