Abstract: A method of producing an anonymized vector for a text mining task in lieu of a feature vector is disclosed. A vocabulary is created from a corpus of documents, each of the corpus of documents having a context that is similar to a set of target documents. The set of target documents is received. The feature vector is generated from a first document of the set of target documents. The feature vector is transformed into a composition vector. A synthetic vector is constructed based on the composition vector. The synthetic vector is shared as the anonymized vector in lieu of the feature vector.

Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives from a client device a request for data stored in a database categorized based on a calculated dimension. The program further generates the calculated dimension based on a subset of the data stored in the database. The program also generates an intermediary data structure by combining the calculated dimension with the data stored in the database. The program further generates results for the request by aggregating the data in the intermediary data structure based on the calculated dimension. The program also provides the results for the request to the client device.

Abstract: Technologies are provided for reducing or eliminating transaction consistency anomalies that can occur during data replication, such as during database table replication.

Abstract: In an example embodiment, a solution is used to provide container volume replication via a container storage replication log and volume buffer synchronization, which is built on top of a container cloud platform whose container metadata and replication runtime configuration are all managed by a storage manager (a service orchestrated by its job scheduler and service orchestrator). This container volume replication ensures the data security for a long-running service in the container. In the case of any disaster, the in-memory database and application data inside of the container can be recovered via volume replication. This provides container volume replication for long-running containerized applications whose states keep changing.

Abstract: An in-memory database server hosting a tenant of a multi-tenant software architecture can receive a definition of a custom data field that is unique to an organization having isolated access to the tenant. The custom data field can extend a standard table defined by central metadata stored at a system tenant of the multi-tenant software architecture. Tenant private metadata that includes the definition can be stored in memory accessible only to the tenant. A tenant-dependent table that includes the custom data field can be formed, for example by retrieving central metadata defining the standard table from the system tenant and adding the custom data field using the definition. The tenant-dependent table can be presented for access via a database client at the organization. Related systems, articles of manufacture, and computer-implemented methods are disclosed.

A pending materialization bit for the at least one page can be set to identify the at least one page for deferred materialization.

Abstract: A method, a system and a computer program product for implicitly partitioning data. An index in a plurality of indexes is selected. The index corresponds to a plurality of ranges of data values stored in a plurality of database slices of a database. A partitioning structure for the selected index is generated. The partitioning structure includes a plurality of hierarchically arranged nodes. Each node corresponds to a range of data values in the plurality of ranges of data values stored and at least one database slice storing corresponding range of data values. Another range of data values is received for storage in the database. Using the partitioning structure, a node in the partitioning structure corresponding to the received range of data values and a corresponding database slice for storing the received range of data values are identified. The received range of data values is stored in the identified database slice.
