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.

Adaptive file storage method and apparatus

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.
