Abstract: Storage file size in distributed data lakes is optimized. At a first ingestion node of a plurality of ingestion nodes, a merge advisory is received from a coordinator. The merge advisory indicates a transaction identifier (ID). Received data associated with the transaction ID is persisted, which includes: determining whether the received data, persisted together in a single file will exceed a maximum desired file size; based on determining that the maximum desired file size will not be exceeded, persisting the received data in a single file; and based on determining that the maximum desired file size will be exceeded, persisting the received data in a plurality of files that each does not exceed the maximum desired file size. A location of the persisted received data in the permanent storage is identified, by the first ingestion node, to the coordinator.

Abstract: References to changing data sets in distributed data lakes are optimized. As part of a transaction, a first message is received. The first message identifies a table and first data to be written to the table. Based on at least the table, the first message is routed to a first ingestion node of a plurality of ingestion nodes. The first data is persisted in temporary storage. Location information of the persisted first data is determined. A data available message comprising a self-describing reference to the first data is published, by the first ingestion node, to a first reader node of a plurality of reader nodes. The self-describing reference identifies the first ingestion node, the location information of the first data, and a range of the first data.

A network function device to configure is identified. A configuration file for configuring the network function device is provided to the CM using the CM UI. The user, form the CM UI, initiates a configuration push of the configuration file by the CM to the network function device to begin configuring the network function device.

Abstract: A framework is described that improves resource utilization during operations executing within workflows of the distributed data processing system (e.g., having a plurality of interconnected nodes) in a disaster recovery (DR) environment configured to support synchronous and asynchronous (i.e., heterogeneous) DR workflows (e.g., generating snapshots and replicating data) that include synchronous replication, asynchronous replication, nearsync (i.e., short duration snapshots of metadata) replication and migration of data objects associated with the workflows for failover (e.g., replication and/or migration) to a secondary site in the event of failure of the primary site. The framework meters (regulates) execution of the operations directed to the workloads so as to efficiently use the resources in a manner that allows timely progress (completion) of certain (e.g., high-frequency) operations and reduction in blocking (stalling) of other (e.g.

Abstract: Automatically selecting an encrypted network connection (such as a VPN tunnel) to use when communicating through another encrypted connection node with which there are multiple encrypted network connections with the computing system. The selection is based predicted latency of that encrypted network connection. The prediction is based on round-trip times of communications over the respective encrypted network connection. This is quite difficult since the encrypted network connection itself is not the entire path of the outgoing message and corresponding incoming message.

Abstract: Intelligent, transaction-aware table placement minimizes cross-host transactions while supporting full transactional semantics and delivering high throughput at low resource utilization. This placement reducing delays caused by cross-host transaction coordination. Examples determine a count of historical interactions between tables, based on at least a transaction history for a plurality of cross-table transactions. Each table provides an abstraction for data, such as by identifying data objects stored in a data lake. For tables on different hosts, having high count of historical interactions, potential cost savings achievable by moving operational control of a first table to the same host as the second table is compared with the potential cost savings achievable by moving operational control of the second table to the same host as the first table. Based on comparing the relative cost savings, one of the tables may be selected.

Specifically, the proposed systems enable the intelligent generation of reports from multiple datasets by automatically determining a proposed set of join configurations for combination of the multiple datasets. Unique identifiers can be assigned to a portion of the combined dataset and the combined dataset can be expanded for performing an aggregation operation associated with the portion of the combined dataset by referencing the one or more unique identifiers. Reports can be generated based on the combined dataset and the aggregation operation.

Abstract: A process of drug shortage prediction includes defining a classifier and loading a listing of drug shortage events at different times in association with different drugs. Over different periods of time, transactions between nodes of the pharmaceutical supply chain are read on a data bus of a digital supply network computing platform, each indicating a receipt of a particular drug by a particular dispensary. Drug shortage events are then correlated with ones of the transactions at a specified duration of time preceding the drug shortage events. Consequently, the classifier can be trained with the correlated transactions annotated as giving rise to the drug shortage events. Finally, the classifier receives queries with newly observed transactions on the data bus and, in response, a likelihood is determined that a drug shortage event for a specific one of the drugs will occur at the specified duration of time following the newly observed transactions.

Abstract: A version control interface for data provides a layer of abstraction that permits multiple readers and writers to access data lakes concurrently. An overlay file system, based on a data structure such as a tree, is used on top of one or more underlying storage instances to implement the interface. Each tree node tree is identified and accessed by means of any universally unique identifiers. Copy-on-write with the tree data structure implements snapshots of the overlay file system. The snapshots support a long-lived master branch, with point-in-time snapshots of its history, and one or more short-lived private branches. As data objects are written to the data lake, the private branch corresponding to a writer is updated. The private branches are merged back into the master branch using any merging logic, and conflict resolution policies are implemented. Readers read from the updated master branch or from any of the private branches.
