Abstract: Techniques are disclosed relating to a computer system accessing a client credential set to authenticate with a destination computer system. A computer system may, subsequent to receiving an indication to make available an application for a particular user, retrieve configuration data specifying a reference to a key value. The computer system may maintain a data object that includes a client credential set for the particular user. In response to an occurrence of an event associated with the application, the computer system may access the client credential set of the particular user from the data object using the key value and an indication of the particular user. The computer system may then send a request including the client credential set to a destination computer system for authentication with the destination computer system and receive a response indicating whether the computer system has been authenticated.

Abstract: Techniques are disclosed relating to storing location information about storage nodes in cookies. A cloud-based service may send location requests to an orchestration service that instantiated storage nodes included in a storage cluster of the cloud-based service. The cloud-based service may receive location information that identifies in which computer zone that a given storage node is located. The cloud-based service may store the location information in cookies at a metadata store that is shared among the storage nodes. The cloud-based service may receive, from a client node, a search request to identify ones of the storage nodes that store particular data. The cloud-based service may return a set of cookies corresponding to identified storage nodes. The set of cookies may enable the client node to determine whether there is a storage node that stores the particular data and is within the same computer zone as the client node.

A message identifying a difference between the first copy of the database object and a second copy of the database object may be transmitted to a remote computing device.

Abstract: Techniques are disclosed relating to the distribution of database key permissions. A database system may distribute first permission information to a plurality of database nodes that identifies a distribution of key range permissions to ones of the plurality of database nodes. A given key range permission being distributed to a given database node may permit that database node to write records whose keys fall within a key range associated with the given key range permission. The database system may receive, from a first database node, a request for a first key range permission provisioned to a second database node. The database system may modify the first permission information to derive second permission information that provisions the first key range permission to the first database node instead of the second database node. The database system may distribute the second permission information to ones of the plurality of database nodes.

Abstract: In various embodiments, a data storage system maintains a data store for a plurality of groups of users, where the data store includes a first section that is accessible by a first group of users, but not a second group of users, via the data storage system. In response to receiving, from a first user of the first group of users, a request to share data with the second group of users, the data storage system sends a request to a second user of the second group of users. Subsequent to receiving an acceptance from the second user, the data is stored in a second object in a second section of the data store that is accessible by the second group of users, but not the first group of users, via the data storage system.

Abstract: Embodiments described herein provide a provide a fully unsupervised model for text compression. Specifically, the unsupervised model is configured to identify an optimal deletion path for each input sequence of texts (e.g., a sentence) and words from the input sequence are gradually deleted along the deletion path. To identify the optimal deletion path, the unsupervised model may adopt a pretrained bidirectional language model (BERT) to score each candidate deletion based on the average perplexity of the resulting sentence and performs a simple greedy look-ahead tree search to select the best deletion for each step.

Abstract: Implementations are described for automatically storing, in a blockchain, metrics that relate to payments. In one implementation, permissions that identify a set of metrics are retrieved from a database. The permissions are stored by a tenant of a multi-tenant system to grant permission to the multi-tenant system to store the metrics for a second tenant. A metric is selected from the set of metrics, based on a determination that a value of the metric is to be updated responsive to a payment in a transaction between the first and second tenants where the payment has been successfully processed. The value of the metric is determined for the second tenant based on data relating to the payment. The value of the metric is stored, in the blockchain, with an identifier that uniquely identifies the second tenant in the blockchain.

Abstract: In a computing environment, a set of executing processes each having associated resources are provided. Aggregate resources for the computing environment include multiple different types of resources. A utilization level for each of the resources within the computing environment is evaluated to determine an unconsumed capacity for each of the resources below a utilization threshold. The utilization threshold is resource-dependent. An indication of at least a portion of unconsumed capacity for each of the resources below the utilization threshold is gathered. The unconsumed portion for each of the resources below the utilization threshold is exposed for consumption by other executing processes.
