Abstract: Computer-implemented systems and methods for classifying movement of an object are provided. Geolocation data for an object and timestamps associated with the geolocation data are processed to automatically identify a movement of the object. The movement is characterized by at least (i) timing data, and (ii) location data indicative of starting and ending locations of the object. One or more criteria for classifying the identified movement are accessed, where the one or more criteria are based on historical data for previous movements. An algorithm that evaluates the timing data and the location data of the identified movement against the one or more criteria is applied. The algorithm is configured to automatically assign a classification of a plurality of classifications to the identified movement based on the evaluation. A determination of whether to provide information on the identified movement to an output destination is made based on the assigned classification.

Abstract: Methods, systems, and computer program products for converting a database table and implementing upgrades and/or migrations are described. A bridge schema comprising a bridge view for a table in a database of an original schema is created and a bridge application server instance is created, the bridge application server instance configured to utilize the bridge schema to access the table of the original schema. The table of the original schema is revised to conform to a specified target schema and a target application server instance configured to access the revised table is created.

The database object can be marked for materialization upon completion of all of the plurality of operations of the transaction thread such that the column and the changes are materialized from the in-memory array to one or more pages stored on a persistent storage based on the marking.

Abstract: A commit event to a database table of a first set of database tables, of a distributed database system, can be detected. The first set of database tables can have a set of first table characteristic and the commit event can have a set of commit event characteristics. The commit event can be correlated to a database table of a second set of database tables based on the set of commit event characteristics. The commit event can be assigned a state based on the correlation of the commit event to a database table of the second set of database tables. First and second documents associated with the commit event can be generated. The second document can be based on the state of the commit event and can include adjustment information associated with the commit event and the first document.

Abstract: The present disclosure involves systems, software, and computer implemented methods for providing quality-driven processing of out-of-order data streams based on a configurable quality metric. In one example, the method includes identifying a configurable quality metric defined by a user or application for executing continuous queries over a sliding window, the metric specifying a user requirement for the quality of the continuous query result. A quality threshold metric is calculated based on the configurable quality metric, the configurable quality metric associated with a size of an adaptation buffer for incoming tuples of the query. In response to receiving a signal indicating a new query result, a sliding window prior to a current time is identified. A runtime quality metric associated with the incoming tuples for the sliding window is measured, and the adaptation buffer is modified based on a difference between the quality threshold metric and the measured runtime quality metric.

Abstract: Execution of a page flusher is initiated in an in-memory database system in which pages are loaded into memory and having associated physical disk storage. Thereafter, pages are identified that have been loaded into the memory of the database system and which have been modified. These identified pages are to be flushed to the physical disk storage. Each page is assigned with a different ordered physical page number. Asynchronous write I/O is later triggered causing the identified pages to be flushed to the physical disk storage and stored in the physical disk storage according to their assigned physical page numbers.

Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives, from a requestor, a query for data comprising a condition on a column of a table. The table includes a plurality of records divided into a plurality of zones. The program further determines a set of zones in the plurality of zones that include records that satisfy the condition based on a plurality of tallies associated with the plurality of zones. Each tally in the plurality of tallies is for indicating whether a zone in the plurality of zones include records with data values in the column of the table that satisfy the condition. The program also determines a result set of records in the table that satisfy the condition based on records in the set of zones. The program further sends the result set of records to the requestor.

Abstract: In one aspect there is a method. The method may include associating a query received from an application with a hint, wherein the hint modifies an execution of the query. The method may further include an optimizer to compile the query according to the hint to produce a second query plan. When no hint is associated with the query, the optimizer may produce a first query plan. The method may further include storing the hint in a persistent table to enable state preservation during a database restart or binary upgrade, and/or executing the query using the second query plan.

Abstract: Techniques are described for managing compute and storage resources in a container-based, multi-tenant, computing infrastructure. In some implementations, a plurality of containers may each execute an instance of a software framework. Each container may include compute capacity and storage capacity according to the executed framework. Containers may be allocated among clusters in a multi-tenant, cloud-based computing environment based on measured demand for compute capacity and/or storage capacity in the various clusters. In some implementations, a scheduler (e.g., a Level 2 scheduler, or a scheduler of schedulers) determines whether to move compute containers between clusters within a multi-tenant environment, to provide performance improvements, resource utilization efficiency, and cost reduction within the data center, and to satisfy tenant requests for compute and/or storage resources.

Abstract: Customer churn risk scores are based on a multi-variable churn risk model relating customer and customer account characteristics to a risk of customer churn. A computer-implemented method of generating and presenting churn risk scores of customers of a telecommunication provider involves analyzing, on an in-memory database platform, customer call data records and customer records to calculate a churn likelihood value, an influence factor value, and an average spend value for each customer. The method assigns a churn risk score to each customer according to the model using the calculated churn likelihood value, the calculated influence factor value, and the calculated average spend value as input to the model. The churn risk scores for one or more customers are displayed visually on an interactive computer-user interface (UI).
