Abstract: An adaptive file storage method and apparatus is disclosed. The method includes determining a cold and hot attribute of a file, and performing coding storage processing or transcoding storage processing on the file according to the cold and hot attribute of the file. Therefore, a requirement of the cold and hot attribute of the file for storage overheads and restoration costs can be fully considered. In addition, the used coding technology has high reliability and a high coding speed. Therefore, comprehensive performance in multiple dimensions of storage overheads, restoration costs, reliability, and an coding speed can be improved.

Abstract: A resource coordination method, an apparatus, and a system for a database cluster, which include an active coordinator node obtains status information corresponding to each processing node in multiple processing nodes, where the status information is used to indicate an operating load status of the processing node, determines, according to the status information corresponding to each processing node in multiple processing nodes, whether the active coordinator node has an idle resource whose capacity is a preset threshold X, and if the active coordinator node has the idle resource whose capacity is the preset threshold X, instructs each processing node to upload subsequently generated clean page data to the active coordinator node.

Abstract: Embodiments of the present disclosure provide concurrency control, including receiving a plurality of transaction operation requests, where each transaction operation request includes operation object information and operation type information, the operation object information is used to indicate an operation object of the transaction operation request, and the operation type information includes a write operation or a read operation, making a lock-use application according to the at least two transaction operation requests, and determining, according to a requested lock status and a current lock status in the lock-use application, whether the application is passed, and if the application is passed, determining to perform concurrency control on the at least two transaction operation requests by using the requested lock status, where the requested and current lock statuses includes at least three modes: a shared read mode, a shared write mode, and an exclusive mode.
