    Abstract: Described herein is a system and method for providing a level 2 connection cache for use with a database environment. In accordance with an embodiment, a second level, or level 2 (L2), connection cache is used to cache no-session connections for use with a database. When a connection is requested, a no-session connection (NSC) can be retrieved from the cache and a database session is attached. Later, when the connection is closed, the database session is logged off and the no-session connection returned to the cache for subsequent use.

    Abstract translation: 这里描述了一种用于提供与数据库环境一起使用的2级连接高速缓存的系统和方法。 根据实施例，使用第二级别或级别2（L2）连接高速缓存来缓存与数据库一起使用的非会话连接。 当请求连接时，可以从高速缓存检索无会话连接（NSC），并附加数据库会话。 稍后，当连接关闭时，数据库会话将被注销，并且无会话连接返回到缓存以供后续使用。

    Abstract: Described herein is a system and method for providing a shareable global cache for use with a database environment. In accordance with an embodiment, a shareable global cache is used for caching connections to database instances. When a request is received for a particular service, the system looks for an idle connection to that service, and, if none is available, locates an existing connection to a database instance serving that service and switches a service on the existing connection to that service.

    Abstract translation: 这里描述了一种用于提供与数据库环境一起使用的可共享全局缓存的系统和方法。 根据实施例，可共享的全局缓存用于缓存到数据库实例的连接。 当接收到特定服务的请求时，系统会查找到该服务的空闲连接，如果没有可用的连接，则将现有连接定位到服务于该服务的数据库实例，并将现有连接上的服务切换到该服务 。

    Abstract: A system and method for connection labeling for use with connection pools, including support for cloud-based multi-tenant environments using connection labeling. In accordance with an embodiment, the system comprises a connection pool, including a plurality of connection objects which provide connections that software applications can use to make requests to access the database, wherein each of the connections can be labeled according to the configuration of particular applications; and a connection pool logic that identifies connections labeled as high-cost connections, and controls the creation or repurposing of high-cost connections to serve requests from the multiple tenants or tenant applications.

    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。
