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.

Authentication identity management for mobile device applications

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. The method may further include switching to a post-migration database access mode, in which database read and update requests are routed to the destination set of storage servers.

Live migration of distributed databases

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.

Layered graph data structure

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. The method may further include switching to a post-migration database access mode, in which database read and update requests are routed to the destination set of storage servers.
