Providing queuing in a log streaming system. A state of each of a set of queues of messages is maintained by sending messages to a state topic in the log streaming system. Responsive to a client writing a message to one of the queues, writing the message to a message topic for the queue in the log streaming system. Responsive to the client reading from one of the queues, reading a message from the message topic for the queue and storing property types relating to the availability of the message in the state topic for the queue by sending messages to the state topic referencing the message in the message topic.

Providing queueing in a log streaming messaging system

A method, system and program product that in response to a segmented server going offline reallocates only those primary and secondary destinations that need to be reallocated on an evenhanded basis, so there is at most a difference of one in the number of buckets allocated to each segmented server before and after re-allocation.

Reallocating secondary destinations on a network switch

A computer-implemented method for software development includes selecting a pre-defined software pattern, the pre-defined software pattern having one or more pre-defined elements, identifying one or more of the pre-defined elements to be modified, obtaining one or more behavioral models, each of the behavioral models specifying a functional behavior for at least one of the identified elements, ascertaining a modification required for each of the identified elements to provide the specified functional behavior, and incorporating the modification into an instance of the software pattern.

Template-based software development

The present invention accordingly provides an application debugger running in a process of a computer system comprising: a debugger memory heap; and an object copier for generating a stateful copy in the debugger memory heap of an application object at runtime wherein the application object is stored in an application memory heap of an application process.

Debugging an application process at runtime

A memory dump of a memory of a computer system having a first set of bytes and a second set of bytes. The first set of bytes includes application data, and the second set of bytes includes a description of a structure of the application data. The memory dump is read by locating the description of a structure of application data; reading the description; defining a runtime data structure in accordance with the description; locating the application data in the memory dump; and reading the application data into the runtime data structure.
