  • Patent number: 11645261
    Abstract: In accordance with an embodiment, described herein is a system and method for heterogeneous database replication from a remote server, for example a remote database server. A capture process can be registered as a replication slave to the remote server, and configured to receive transaction event data from that server. Transaction log events associated with a modification to the database at the remote server can be processed, and output as change data, in a canonical format output, for use with one or more heterogeneous targets, for example a target database server or message queue. The process enables capture of transaction log events associated with database transactions at a remote server that may be located on a different computer or network, or within an access-restricted environment such as a cloud environment, without the need to create additional copies of its transaction logs.

  • Patent number: 10356150
    Abstract: An automated repartitioning agent (ARA) of a storage service determines a repartitioning plan for a storage object. The plan identifies a source set of partitions whose keys are to be distributed among a target number of partitions. The ARA generates a data structure representing the source set, with entries indicating the key sets of corresponding partitions. The ARA implements repartitioning iterations until the keys of the source set have been redistributed. In each iteration, the ARA compares the key set of a selected entry of the data structure with a target key set and performs repartitioning actions based on the result. The repartitioning action may include splitting the selected entry's partition, merging the selected entry's partition with another partition, or designating the selected entry's partition as acceptable.

  • Patent number: 10318490
    Abstract: In embodiments of synchronizing linked assets from unsynchronized file folders, files are organized in folders of a file system, where the folders include a synchronized folder and an unsynchronized folder, the synchronized folder having been selected for synchronization of the files contained in the synchronized folder, and the unsynchronized folder containing linked assets. The files contained in the synchronized folder are synchronized with a network-based memory system that stores an instantiation of the files. A synchronization service can determine that a file contained in the synchronized folder references to one or more of the linked assets contained in the unsynchronized folder. The synchronization service can then synchronize a linked asset from the unsynchronized folder automatically based on criteria associated with the file contained in the synchronized folder.
