US Patent 10929066 User stream aware file systems with user stream detection

Techniques for handling multiple data streams in stream-aware data storage systems. The data storage systems can detect multiple sub-streams in an incoming stream of data, form a group of data blocks corresponding to each respective sub-stream, and associate, bind, and/or assign a stream ID to each data block in the respective sub-stream. The data storage systems can write each group of data blocks having the same stream ID to the same segment of a data log in one or more non-volatile storage devices, and manage and/or maintain, in persistent data storage, attribute information pertaining to the groups of data blocks in the respective sub-streams relative to time periods during which the respective groups of data blocks were written and/or received. The techniques can improve the detection of multiple sub-streams in an incoming stream of data, and improve the management of attribute information pertaining to data blocks in the respective sub-streams.
