摘要： An architecture for a database process that can process many large queries simultaneously without creating bottlenecks uses a separate database server process to act as the interface with the processes generating the database queries, and a database engine process to process the queries. The database server receives the query notifications and queues the query structure it then passes the query to the database engine when it becomes available. The present invention allows the database server to service small queries it receives, such as requests for configuration data which are critical, and allows a configuration of multiple database engines to service several large queries simultaneously. The database engine process does not actively receive requests from the database server. Rather, it requests work from the database as it becomes available employing a time-out mechanism when the database engine is idle. According to another aspect of the present invention, the database processes perform their own load balancing.
摘要翻译：数据库进程的架构可以同时处理许多大型查询而不产生瓶颈，使用单独的数据库服务器进程作为生成数据库查询的进程的接口以及处理查询的数据库引擎进程。数据库服务器接收查询通知，并对查询结构进行排队，然后在查询结果可用时将查询传递给数据库引擎。本发明允许数据库服务器为其接收到的小型查询服务（例如对关键的配置数据的请求）进行服务，并且允许多个数据库引擎的配置同时为多个大型查询服务。数据库引擎进程不主动从数据库服务器接收请求。相反，当数据库引擎处于空闲状态时，它会使用超时机制从数据库中请求工作。根据本发明的另一方面，数据库处理执行它们自己的负载平衡。
