  • Publication number: 20220164323
    Abstract: A distributed storage system includes table controllers collectively storing partitions of a logical table having multiple rows. For each of the partitions, a corresponding table controller stores a subset of the rows of the logical table across individual pages. A management controller updates a schema of the logical table from a first to a second schema definition by, for each of the partitions, sending an update command indicating the second schema definition to the corresponding table controller. The first table controller corresponds to a first partition that includes a first subset of the rows. The first table controller, prior to receiving the update command, includes an identifier of the first schema definition within each page of data for the first subset. Subsequent to receiving the update command, the first table controller, when writing each new page of data for the first subset, includes an identifier of the second schema definition.

  • Patent number: 11297031
    Abstract: A service enables a command that refers to a file system object using a hierarchical namespace identifier to be executed against the file system object in a flat namespace. The service selectively distributes the command to one of a plurality of name resolution nodes based on a directory name included in the hierarchical namespace identifier. The identified node resolves the directory name to a flat namespace identifier that is used to execute the command against the flat namespace. After communicating with at least one storage node to resolve a directory name, each name resolution node stores a mapping of the directory name to the corresponding flat namespace identifier in a cache, so that subsequent resolutions of that directory name may be performed more efficiently. Cache entries may be invalidated when an operation occurs that impacts the relevant mapping and/or based on system considerations such as cache expiry.

  • Patent number: 11183568
    Abstract: Disclosures of the present invention mainly describe a two-dimensional semiconductor device (TDSD), comprising: a two-dimensional semiconductor material (TDSM) layer, a superacid action layer and a superacid solution. The TDSM layer is made of a transition-metal dichalcogenide, and the superacid action layer is formed on the TDSM layer. Particularly, an oxide material is adopted for making the superacid action layer, such that the superacid solution is subsequently applied to the superacid action layer so as to make the superacid solution gets into the superacid action layer by diffusion effect. Experimental data have proved that, letting the superacid solution diffuse into the superacid action layer can not only apply a chemical treatment to the TDSM layer, but also make the TDSD have a luminosity enhancement. Particularly, the luminosity enhancement would not be reduced even if the TDSD contacts with water and/or organic solution during other subsequent manufacturing processes.
