Abstract: A first portion of a distributed catalog service is implemented for a given one of a plurality of distributed processing node clusters associated with respective data zones, each of the clusters being configured to perform processing operations utilizing local data resources locally accessible within its corresponding data zone. The first portion of the distributed catalog service receives a request to identify for each of a plurality of data resources to be utilized by an application initiated in the given cluster whether the data resource is a local or remote data resource relative to the given cluster, and provides a response to the request. The first portion of the distributed catalog service in combination with additional portions implemented for respective additional ones of the distributed processing node clusters collectively provide the distributed catalog service with capability to resolve local or remote status of data resources in each of the data zones.

Abstract: An apparatus comprises a multi-cluster distributed data processing platform. Each of the clusters of the platform is configured to perform processing operations utilizing local data resources accessible within a corresponding data zone. A first application is initiated in one of the clusters, and data resources to be utilized by the application are determined. For one or more of the data resources identified as local data resources for the associated cluster, processing operations are performed utilizing those local data resources in that cluster in accordance with the first application. For one or more of the data resources identified as remote data resources for the associated cluster, one or more additional applications are initiated in one or more additional ones of the clusters. This repeats recursively for each additional application until all processing required by the first application is complete. Processing results from the clusters are aggregated and provided to a client.

Abstract: An apparatus in one embodiment comprises at least one processing device having a processor coupled to a memory. The processing device is configured to receive results of intermediate statistical computations performed on respective ones of a plurality of datasets in respective ones of a plurality of distributed processing nodes configured to communicate over at least one network. The processing device is further configured to perform at least one global statistical computation based at least in part on the results of the intermediate statistical computations, and to utilize a result of the global statistical computation to perform one or more benchmarking operations for specified parameters relating to the plurality of datasets. The distributed processing nodes are associated with respective distinct data zones in which the respective datasets are locally accessible to the respective distributed processing nodes. At least a subset of the receiving, performing and utilizing are repeated in each of a plurality of iterations.

Abstract: A fault tolerance computer implemented method, a computer program product, and a system for allowing asynchronous replication to continue with no lag increase due to RPA failure comprising: creating a consistency group (CG) on a first replication appliance and a shadow copy of the CG on a second replication appliance; sending input/output (IO data), via a splitter, to the CG in a first replication appliance; and sending IO data, via the splitter, to shadow copy of the CG on a second replication appliance.
