Certain example embodiments relate to a computer system for performing a map reduce sequence. Nodes therein include at least one processor and memory and are divided into at least mapper and reducer nodes. Each mapper node executes a map function on input to generate intermediate output elements. Each said intermediate output element includes a first key-value pair. Each element key includes associated map and reduce task identifiers. Each element value includes substantive data, organized as another key-value pair. The intermediate output elements are stored to memory. Each reducer node: retrieves at least intermediate output element values from the memory of a given mapper node, using specified map and reduce task identifiers; stores the retrieved element values to its memory; executes a reduce function on the retrieved element values, in order; and outputs a result from the reduce function for the map reduce sequence. Disk operations advantageously are reduced or eliminated. Show less

Each node in a network of nodes is dynamically configurable to send and/or receive messages using one of brokered and brokerless communication models. At least some of the nodes have a complex event processing (CEP) engine deployed thereto, the CEP engines being configured to operate on messages received by the respective nodes and being classified as one of at least two different types of CEP engines. For each message received by a given node that is to be forwarded to a further node along one of multiple possible paths, the given node is configured to route the message to be forwarded to an intermediate node in one of the possible paths. The intermediate node is selected by the CEP engine of the given node based on metadata associated with the message to be forwarded. Show less

In accordance with embodiments, there are provided mechanisms and methods for propagating security information for an application between a first environment and a second environment. These mechanisms and methods can enable embodiments to propagate changes to security information from a first application instance in a first environment to a second application instance in a second environment. For example, an embodiment can receive security information from an adapter associated with a test… Show more

In accordance with embodiments, there are provided mechanisms and methods for propagating security information for an application between a first environment and a second environment. These mechanisms and methods can enable embodiments to propagate changes to security information from a first application instance in a first environment to a second application instance in a second environment. For example, an embodiment can receive security information from an adapter associated with a test version of an application, and then propagate the security information to a production version of the application residing in a production environment. The ability of embodiments to propagate security information between adapters associated with application versions can enable propagation of changes to security information, i.e., information about changes to permissions, rules, policies and so forth relating to security, between a first environment and a second environment without necessitating taking the production version of the application off line.
