摘要： A method and apparatus for propagating and managing data, transactions and events either within a database, or from one database to another is provided. In one embodiment, messages are propagated from a source to a first queue and a second queue with the queues associated with the same database. The connection from the source to each queue maintains its own propagation job. This method could also be employed with cluster databases.

摘要： A buffered message queue architecture for managing messages in a database management system is disclosed. A “buffered message queue” refers to a message queue implemented in a volatile memory, such as a RAM. The volatile memory may be a shared volatile memory that is accessible by a plurality of processes. The buffered message queue architecture supports a publish and subscribe communication mechanism, where the message producers and message consumers may be decoupled from and independent of each other. The buffered message queue architecture provides all the functionality of a persistent publish-subscriber messaging system, without ever having to store the messages in persistent storage. The buffered message queue architecture provides better performance and scalability since no persistent operations are needed and no UNDO/REDO logs need to be maintained. Messages published to the buffered message queue are delivered to all eligible subscribers at least once, even in the event of failures, as long as the application is “repeatable.” The buffered message queue architecture also includes management mechanisms for performing buffered message queue cleanup and also for providing unlimited size buffered message queues when limited amounts of shared memory are available. The architecture also includes “zero copy” buffered message queues and provides for transaction-based enqueue of messages.
摘要翻译： 公开了一种用于管理数据库管理系统中的消息的缓冲消息队列架构。 “缓冲消息队列”是指在诸如RAM的易失性存储器中实现的消息队列。 易失性存储器可以是可由多个进程访问的共享易失性存储器。 缓冲消息队列架构支持发布和订阅通信机制，消息生成器和消息消费者可以彼此分离并且彼此独立。 缓冲消息队列体系结构提供了持久性发布 - 订阅者消息系统的所有功能，而无需将消息存储在持久存储中。 缓冲消息队列架构提供更好的性能和可扩展性，因为不需要持续的操作，并且不需要维护UNDO / REDO日志。 只要应用程序是“可重复的”，发布到缓冲消息队列的消息至少发送一次，即使发生故障。 缓冲消息队列架构还包括用于执行缓冲消息队列清理的管理机制，并且还用于当有限量的共享存储器可用时提供无限大小的缓冲消息队列。 该架构还包括“零拷贝”缓冲消息队列，并提供基于事务的消息队列。

摘要： A method and apparatus for managing a database is provided. A database management system conducts a plurality of database transactions with a plurality of clients. An event may be detected as a result of one of the transactions. The event is mapped to an independent database action. In response to detecting the event, the independent database action is executed without interference from the transaction that caused the event.

摘要： Techniques for detecting patterns in data streams. A pattern to be detected may be specified using a regular expression. Events received in data streams are then processed during runtime to detect occurrences of the pattern specified by the regular expression in the data stream. If the pattern to be matched belongs to a certain predetermined class of patterns, then a pattern matching technique that is customized for that class of patterns is used during the runtime events processing.

摘要： A framework for extending the capabilities of an event processing system using one or more plug-in components referred to herein as data cartridges. Generally speaking, a data cartridge is a self-contained unit of data that can be registered with an event processing system and can store information pertaining to one or more objects (referred to herein as extensible objects) that are not natively supported by the system. Examples of such extensible objects can include data types, functions, indexes, data sources, and others. By interacting with a data cartridge, an event processing system can compile and execute queries that reference extensible objects defined in the data cartridge, thereby extending the system beyond its native capabilities.

摘要： Techniques for managing messages in computer systems are provided. In one embodiment, in response to a publisher attempting to enqueue a message in a queue, a determination is made whether a condition is satisfied. The condition is based on the current usage of the queue by the publisher. Based on whether the condition is satisfied, a decision is made whether to enqueue the message in the queue. The decision whether to enqueue the message may comprise restricting the publisher from enqueueing any more messages in the queue until the same or a different condition is satisfied.

摘要： Techniques for managing memory usage in a processing system are provided. This may be achieved by receiving a data stream including multiple tuples and determining a query plan that was generated for a continuous query applied to the multiple tuples in the data stream. The query plan may include one or more operators. Before scheduling an operator in the query plan, it is determined when an eviction is to be performed based a level of free memory of the processing system. An eviction candidate is determined and a page associated with the eviction candidate is evicted from the memory to a persistent storage.

摘要： Techniques for managing memory usage of a processing system by spilling data from a memory to a persistent store based upon an evict policy are provided. A triggering event is detected. In response to the triggering event and based on the evict policy, it is determined whether data from the memory of the processing system is to be spilled to the persistent storage. The determination is made by comparing a level of free memory of the processing system with a threshold specified by the evict policy. The data is evicted from the memory.
