Event-Based Communication Sample Clauses

Event-Based Communication. ‌ Since the MICO framework implements a service-oriented architecture, the main means of communica- tion between components is events. Using an event-based mechanism allows components implemented in different environments and running on different machines to properly interact with each other. The event communication will be implemented based on Apache Zookeeper17, a centralized service for stor- ing configuration and coordinating/synchronizing different services. The following Zookeeper function- alities will be used by the MICO framework • Configuration Management: allows components and machines to access and store their con- figuration in a central service; using centralized configuration management, components can be relocated and executed on different machines without too much effort; for configuration man- agement, the MICO framework will implement Zookeeper access through the Apache Commons Configuration API18 • Synchronization: allows components to create locks (e.g. on content items or content parts) in a central service to avoid other components running on different machines to interfer with an 17xxxx://xxxxxxxxx.xxxxxx.xxx/ Figure 7 OpenRDF Sesame API stack ongoing computation; for synchronization purposes the MICO framework will provide imple- mentations of the Java Lock API backed by Zookeeper • Producer-Consumer Queues: allow for simple distributed event communication where con- xxxxxx can subscribe to a certain queue while producers (possibly running on different machines) can publish to queues; for event communication, the MICO framework will provide implementa- tions of Java Listeners as well as of the Java Collection API backed by Zookeeper Zookeeper structures data in a filesystem-like hierarchical structure that can be traversed from the root (see Figure 6). Entries (“nodes”) in this hierarchy can be either normal nodes, which are persistent across restarts, or ephemeral nodes, which exist as long as the client which created it is connected to the server. Nodes can store any kind of data, and clients can register listeners on nodes to be notified of changes to this data. Zookeeper gives certain guarantees that allow using these fundamental structures to implement the functionalities described above. Using Zookeeper has several advantages for the MICO framework: first, it is a reliable and tested platform used by many enterprise users; second, there is a plethora of libraries for connecting and interacting with Zookeeper servers; and thir...

  • When Must Electronic Communications Be Retained? Email that qualifies under FOIA as a public record will need to be stored pursuant to the Local Records Act, only if it is evidence of the District's organization, function, policies, procedures, or activities or contains informational data appropriate for preservation (Local Records Act, 50 ILCS 205/). An example is any email from a Board officer concerning a decision made in his or her capacity as an officer. If a Board member uses his or her personal email, he or she must copy this type of email to the appropriate District office where it will be stored. If made available, Board members should use their email accounts provided by the District and the District will automatically store the official record messages. The District will delete these official record messages as provided in an applicable, approved retention schedule. Of course, email pertaining to public business that is sent or received by a Board Member using a District-issued device or email address will be subject to FOIA, even if the email does not need to be retained under the Local Records Act.
