摘要： In one aspect, a computerized method for expanding a graphics processing unit (GPU) memory footprint based on a hybrid-memory of a distributed database system (DDBS) includes the step of providing the DDBS. The DDBS is modified to include a plurality of GPUs; providing a local memory of a GPU of the plurality of GPUs. The method includes the step of filling the local memory of the GPU with one or more digests from the DDBS. The method includes the step of running a distributed general-purpose cluster-computing framework instance on the local memory of the GPU. The method includes the step of fetching data from the local memory of the GPU using the distributed general-purpose cluster-computing framework instance. The method includes the step of storing a result of the fetch operation in the DDBS to extend the local memory of the GPU to handle more data than what is fitted into the local memory of the GPU.

摘要： A computerized method useful for node cluster formation and management in a distributed database system includes the step of providing a set of database nodes in a database cluster. Each node of the set of database nodes comprises a cluster management module, a heartbeat module, and a globally unique node identifier. The cluster management module manages cluster membership by maintaining a succession list. The succession list comprises a list of all current members in the database cluster. The heartbeat module communicates a pulse message to every other node in the set of database nodes. The method includes the step of maintaining, with each heartbeat module of each database node, an adjacency list.

摘要： Embodiments of the invention are directed to determining a universal device identifier (UDID) for a client device, based on multiple service-dependent identifiers (SDIDs) used by client applications, websites, or other services to identify the client device. SDID types are prioritized with pre-assigned weights. A received SDID causes a single database read to access all other SDIDs, and any existing UDID(s) associated with the client device. A final UDID is created or selected based on the SDID weights. The database is updated in a sequence that enables self recovery of a prior UDID in case of database error during update. First, any non-selected UDID records are updated with the final UDID. Next, lower weighted SDID records are updated. The final UDID record is updated. The highest weighted SDID record is updated last, to preserve the prior UDID as long as possible in case of update error, which aborts the remaining update.

摘要： In one example, a synchronization server includes logic operable to engage in a first synchronization session with a client device, wherein client modifications and server modifications may be exchanged based, at least in part, on synchronization data stored locally. The synchronization server further includes logic operable to initiate a query of a remote database (e.g., having data associated with the synchronization data) to determine differences between the synchronization data stored locally and associated data stored remotely. The synchronization server is further operable to initiate an exchange of further server modifications based on the differences between the synchronization data stored locally and the associated data stored remotely. In one example, the server may engage in a second synchronization session with the client device to update the client device with differences to the synchronization data stored locally and the remote database.
