Abstract: Methods, systems, and devices are described that support extensible data mapping. A data mapping server may receive an indication of a source schema for a data source and may receive a user input indicating creation of a custom data object to handle the source schema. The server may create the custom data object based on the user input. The data mapping server may automatically map one or more data fields for a source data object (e.g., based on the source schema) to one or more custom data fields for the custom data object (e.g., based on a custom schema). The server may import a set of data records stored at the data source and may store the data records in a database system according to the custom schema based on the data mapping. The stored custom data objects may be used for segmentation, activation, analysis, or some combination thereof.

Abstract: A data server may support segment identification based on a selected user profile. For example, a user may select a user profile as the basis for identifying a segment of additional user profiles. The server may identify attributes associated with the selected user identifier and generate an expression based on the identified subset. The expression may include a normalization function corresponding to at least one attribute. The normalization function may identify correlated attribute values for an attribute associated with he selected user profile. The data server may query a data storage system to identify the additional user profiles based on the expression. The data server may also support user defined Boolean expressions such that the expression is used to identify user identifiers associated with a first attribute and a second attribute.

Abstract: An application may support ingestion of data to a data server. A user may identify the data source, and the server may determine a connector corresponding to the identified data source. The server may support a plurality of connectors for data ingestion. Based on the selected source, the user may select a data channel type, where the data channel type is associated with one or more packaged data sets that include different data set types. The server may then ingest the data set using the determined connector. The application may further support mapping of source and target attributes, custom mapping, and transformation functions.

Abstract: An example method of live migration of distributed databases may include implementing a first database access mode with respect to a distributed database to be migrated from an original set of storage servers to a destination set of storage servers, wherein, in the first database access mode, database read requests are routed to the original set of storage servers and database update requests are routed to both the original set of storage servers and the destination set of storage servers. The method may further include copying a plurality of records of the distributed database from the original set of storage servers to the destination set of storage servers. The method may further include switching to a second database access mode, in which database read requests are routed to the destination set of storage servers and database update requests are routed to both the original set of storage servers and the destination set of storage servers.

Abstract: An identity authenticator receives a first authentication credential from a first application at a first computing device. The identity authenticator then determines that the first authentication credential is associated with a second authentication credential for the first application at a second computing device based on a stored authentication identity. The identity authenticator then provides a stored execution state for the first application to the first computing device, wherein the stored execution state is associated, based on the stored authentication identity, with at least one of the first authentication credential or the second authentication credential.

Abstract: An example method of live migration of distributed databases may include implementing a first intermediate database access mode with respect to a distributed database to be migrated from an original set of storage servers to a destination set of storage servers, wherein, in the first database access mode, database read requests are routed to the original set of storage servers and database update requests are routed to both the original set of storage servers and the destination set of storage servers. The method may further include copying a plurality of records of the distributed database from the original set of storage servers to the destination set of storage servers. The method may further include switching to a second intermediate database access mode, in which database read requests are routed to the destination set of storage servers and database update requests are routed to both the original set of storage servers and the destination set of storage servers.

Abstract: A layered graph data structure can be stored using a vertex table and an edge table. The vertex table includes a vertex identifier column and a first graph identifier column. The edge table includes a second graph identifier column, a node identifier column, and an edge type column. Queries of the layered graph data structure include a target entity and a graph level, and iterative searching of the vertex table and the edge table is performed based on the graph level and data stored in edge type column.

Abstract: A method and system for providing audio assistance for non-visual navigation of data. The method includes receiving a scroll input; determining a page length associated with the data; associating the page length with a plurality of steps; associating an audio pattern to each step; determining a step, of the plurality of steps, that corresponds to the scroll input; and playing, to the user, the audio pattern corresponding to the step. The system includes an electronic device, a communication interface, a memory and a processor to receive a scroll input, to determine a page length associated with the data, to associate the page length with a plurality of steps, to associate an audio pattern to each step, to determine a step, of the plurality of steps, that corresponds to the scroll input and to play, to the user, the audio pattern corresponding to the step.
