Abstract: A computerized method for ingesting data from a relational database into a data lake is provided, wherein a user-defined function (UDF) is associated with a standard operation of extract, transform, load, or ETL, of an ETL pipeline. This UDF is triggered upon performing the standard operation and thereby allow a code associated with the UDF to be executed. Upon migrating data from one or more data sources into the relational database, the standard operation is executed, which triggers the UDF and, in turn, an execution of the code. As per the execution of this code, an entity running on the data lake is notified that a set of data migrated to the relational database is to be ingested according to given ingestion modalities specified by the code. Finally, the set of data can be ingested into the data lake according to the modalities. Related computer program products are also provided.

Abstract: An approach is provided for aggregating business data. Based on received columns, attributes, and keys of a dataset, the dataset is registered in a central hub of datasets which include data that is independently and locally maintained. Other datasets in the central hub that include columns, attributes, or keys that match the received columns, attributes, or keys, respectively, are determined and displayed. Responsive to receiving a user selection of one or more of the displayed datasets, cross-links between the dataset and each of the one or more selected datasets are generated. Based on a modification of a selected one of the cross-links and a second user interacting with the central hub, the modification and other cross-link(s) are displayed.

Abstract: Embodiments of the invention is directed to a method for connecting a device to a network. An example method comprises providing a device assigned with a device identifier and an asymmetric cryptographic key pair that includes a public key and a private key. The device stores the private key on a memory thereof. The device is provided with information as to the assigned device identifier and/or the public key. This information is detectable by a detector so as to be transmissible to a server for it to identify the device identifier and the public key assigned to the device.

Abstract: A plurality of protocol stacks are deployed. Each of the protocol stacks includes a plurality of composable protocol modules, and each of the composable protocol modules implements common interfaces. It is detected that a first given one of a plurality of clients wishes to connect to a publication-subscription engine and it is determined whether the first given one of the plurality of clients is to be connected in a secure manner. Responsive to determining that the first given one of the plurality of clients is to be connected in the secure manner, an encrypted instance of a first appropriate one of the plurality of protocol stacks is instantiated to effectuate the secure connection. The first given one of the plurality of clients is authenticated and authorized.

Abstract: An approach is provided for aggregating business data. Based on received columns, attributes, and keys of a dataset, the dataset is registered in a central hub of datasets which include data that is independently and locally maintained. Other datasets in the central hub that include columns, attributes, or keys that match the received columns, attributes, or keys, respectively, are determined and displayed. Responsive to receiving a user selection of one or more of the displayed datasets, cross-links between the dataset and each of the one or more selected datasets are generated. Based on a modification of a selected one of the cross-links and a second user interacting with the central hub, the modification and other cross-link(s) are displayed. Based on the second user's selection of the modification or one of the other cross-link(s), an analysis of data in the dataset is performed.

Abstract: Embodiments of the invention provide a method, system, and computer program product for selecting a server as a selected server for performing a specified function in a distributed computing system. In one embodiment, the method comprises identifying a group of servers in the system; and choosing as the selected server the server that has been in the system the longest. In one embodiment, each of the servers in the group has a respective contention period, during which the server sends a contention message, and the selected server is chosen using these contention messages. The servers in the group may have imperfect clock synchronization. In this case, the contention periods of the servers is kept greater than the maximum difference between the server clocks. The invention may be used to select a name server, or to select a server for another service.

Abstract: An approach is provided for aggregating business data. Based on received columns, attributes, and keys of a dataset, the dataset is registered in a central hub of datasets which include data that is independently and locally maintained. Initial or updated data is loaded into the dataset in the central hub. Other datasets in the central hub that include columns, attributes, or keys that match the received columns, attributes, or keys, respectively, are determined and displayed. In response to receiving a user selection of one or more of the displayed datasets, cross-links between the dataset and each of the one or more selected datasets are automatically generated. The cross-links are based on the columns, attributes, or keys of the displayed datasets that match the received columns, attributes or keys. The cross-links provide an aggregation of business data in the dataset and the one or more selected datasets.
