Abstract: Embodiments of the present invention provide a method and system for processing a query on a set of data blocks in analytical databases. The query is on a set of data blocks, having at least one attribute and specifies at least one selection condition on the attribute. The selection condition is associated with at least one selection expression. Attribute value information on each attribute is generated for each data block. Next, a condition is generated on each attribute to negate the selection expression, if the selection expression has a negation operator. Additional conditions are generated for each selection expression that does not contain a negation operation. The attribute value is used to select the positive and negative subsets of data blocks for each condition. Next, a negative subset that does not require processing to evaluate the query is skipped and the positive subsets and the non-skipped negative subsets are processed.

Abstract: Methods and apparatuses are described for synchronization of metadata between databases in a cloud computing environment. A computing device identifies jobs that synchronize metadata from a first database instance to a second database instance, each job comprising synchronization tasks for a different portion of the metadata. The computing device determines a count of the synchronization tasks for each job. The computing device allocates each job to a first queue where the count of the synchronization tasks for the job is below a threshold value, and allocates the synchronization tasks for each job to a second queue where the count of the synchronization tasks for the job is at or above the threshold value. The computing device executes the jobs in the first queue and executes the synchronization tasks in the second queue to synchronize the corresponding metadata to the second database instance.

Abstract: A plurality of instances of probe data are received. Each instance of probe data corresponds to travel of a vehicle apparatus along a first segment, comprises an indication of at least one parameter characterizing the travel of the vehicle apparatus along the first segment. The at least one parameter is extracted from the instances of probe data to generate a distribution of parameters. One or more clusters of instances of probe data are identified based on the distribution of parameters. Responsive to identifying two or more clusters, a representative at least one parameter is determined for each cluster, and an element of a data structure is modified based thereon for each cluster. Responsive to identifying only one cluster of instances of probe data, the data structure is not modified based on the cluster. A navigation application is configured to use the data structure to perform a navigation function.

Abstract: A method for synchronizing a local file system (LFS) and a remote (cloud) file system (RFS) includes the step of storing events indicative of differences between the LFS and the RFS, where the events are associated with file system objects of the LFS and RFS. The method further includes the steps of prioritizing the events, generating file system operations for the events based at least in part on the prioritization of the events, and performing at least some of the file system operations to synchronize the LFS and RFS. Prioritizing the events includes defining a plurality of service classes (e.g., based on type of event, event attribute, etc.), assigning a priority to each of the service classes, and assigning each event to one of said service classes. Systems are also described. The invention allocates limited synchronization resources based on a predefined policy to synchronize important file system objects sooner.

Requests to store or retrieve information to or from the hierarchical data maps issued by a client computer system communicating with the server computer system via a network are responded to by the application.

Abstract: In non-limiting examples, passive information is used to verify the location of a client computing device and to create segment categories for directed information using location-based services and/or applications. In aspects, passive information is received from a client computing device. The client computing device is detected as being located at a predicted venue using the passive information. It may be determined whether directed information associated with the predicted venue has been displayed at an earlier time on a predetermined portion of the client computing device. In response to determining directed information associated with the predicted venue has been displayed on the predetermined portion of the client computing device, a statistical model may be applied to calculate a confidence score that the client computing device is located at the predicted venue. When the confidence score meets a predetermined threshold, a directed information conversion record may be stored in a data store.

Abstract: A framework for facilitating communication between a multi-cluster management (MCM) system and the clusters managed by the system is provided. According to one set of embodiments, the framework comprises two independent, unidirectional communications channels: a first channel (i.e., “intent channel”) that flows from the MCM system to each cluster, and a second channel (i.e., “data sync channel”) that flows from each cluster to the MCM system. Through the intent channel, the MCM system can deliver control information to each cluster for actuating management changes/operations therein in a manner that is robust against network dropouts and packet loss. Through the data sync channel, the MCM system can collect and process status information from each cluster (such as, e.g., object state transitions triggered by the control information sent via the intent channel) in a manner that can efficiently scale to support large numbers of clusters.

The duplicate catalog object can be deleted upon completion of modifying the data associated with the original catalog object.

Abstract: Atomic partition scheme updates to partition items may be implemented by a time series database. A time threshold may be assigned to partition scheme update so that the time threshold may be applied across a set of ingestion nodes that may apply the partition scheme update the same. A request to store an item with a timestamp less than the time threshold may be stored in one partition of the time series database, while the item may be stored in a different partition of the time series database if the item has timestamp greater than or equal to the time threshold.
