Message ordering is a fundamental abstraction in distributed systems. However, ordering guarantees are usually purely "syntactic," that is, message "semantics" is not taken into consideration despi...doi:10.1007/3-540-48169-9_7Fernando Pedone...
Composite Subscriptions in Content-Based Publish/Subscribe Systems Distributed publish/subscribe systems are naturally suited for processing events in distributed systems. However, support for expressing patterns about distributed events and algorithms for detecting correlations among these events are s... G...
Beyond this, the ordering of messages consumed by a client can have only a rough relationship to the order in which they were produced. This is because the delivery of messages to a number of destinations and the delivery from those destinations can depend on a number of issues that affect ...
in other words, we are interested in deducing the causal precedence relation between events from their time stamps. To do so we need to define the so-called strong clock condition. Thestrong clock conditionrequires an equivalence between the causal precedence and the ordering of the time stamps ...
There is a growing trend in using mobile computing environment for several applications, and It is important that the mobile systems are provided adequate support both at the systems level and at the communication level. Causal ordering is a useful property, particularly in applications that involve...
Specification and verification of hierarchical systems by refinement The specification of communication behavior is fundamental in developing interoperable transactions. In particular, the temporal ordering of messages excha... AlAchhab 被引量: 4发表: 2004年 Specification and Verification of the IEEE...
Publish-subscribe use cases are frequently associated with stateful applications. Stateful applications care about the order of messages received because the ordering of messages determines the state of the application and will as a result impact the correctness of whatever processing logic the application...
If true, put the messages in reverse order (where the default ordering applied to a message expression is based on Java’s string lexical ordering, as defined by String.compareTo()). For example, if you want to resequence messages from JMS queues based on JMSPriority, you would n...
Therefore, the message queuing system 102 uses a timestamp-based ordering algorithm (using, in one embodiment, the Appearances 410 column family of a queue) to realize timer management for visibility timeout and best-effort in-order delivery together. By using a timestamp-based ordering algorithm...
We separated the ordering logic from the email management logic and brought the two services together using a message queue system. This way ourordersservice can handle order placement while theemailsservice dispatches the emails to the users. ...
