Embodiment approach

[0171] The computing cluster management method described above may be implemented, for example, using a programmable computing system executing suitable software instructions, or the method may be implemented in suitable hardware, such as a Field Programmable Gate Array (FPGA) or in some hybrid form. For example, in a programmed approach, software may comprise one or more computer programs in one or more programmed or programmable computing systems (which may be of various architectures, such as distributed client / server, or power grid) processes performed on computing systems each comprising at least one processor, at least one data storage system (including volatile and / or non-volatile memory and / or storage elements), at least one user interface (for using at least one An input device or port receives input and is operable to provide output using at least one output device or port). Software may include one or more modules of a larger program that, for example, provides serv...

Abstract

A method for managing data in a distributed data processing system including a number of processing nodes includes storing data units in data stores that are associated with a number of different levels of durability. The method includes maintaining indicators including a first indicator associated with a first durability level and a second indicator associated with a second durability level. Thefirst indicator is maintained to reflect a time interval at which all sets of data units associated with the time interval are stored at the first durability level. The second indicator is maintainedto reflect a timer interval at which all sets of data units associated with the time interval are stored at the second durability level. The first and second indicators are used to manage processing of the data units in the distributed data processing system.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application Serial No. 62 / 579,225, filed October 31, 2017, which is incorporated herein by reference. Background technique [0003] This specification is about managing computing clusters. [0004] One approach to dataflow computing utilizes a graph-based representation, where computational components corresponding to nodes (vertices) of the graph are connected via links (directed edges) to the graph (called a "dataflow graph"). Corresponding data flow coupling. A downstream component connected to an upstream component by a dataflow link receives an ordered stream of input data elements and processes the input data elements in the order received to optionally generate one or more corresponding streams of output data elements. A system for performing such graph-based computations is described in prior US Patent No. 5,966,072, entitled "EXECUTING COMPUTATIONS EXPRESSED AS GRAPHS," w...
