  • Patent number: 8868624
    Abstract: Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the manipulation of Blobs in a structured storage system includes receiving a request for a Blob, which may be located by way of a Blob pointer. The Blob pointer allows for the data, such as properties, of the Blob to be identified and located. Expired properties are garbage collected as a manipulation of the Blob data within a structured storage system. In an embodiment, the Blob is identified by a key that is utilized within a primary structured index to located the requested Blob. In another embodiment, the requested Blob is located utilizing a secondary hash index. In an additional embodiment, the Blob is locate utilizing a file table.

  • Patent number: 8620884
    Abstract: Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the structured storage of Blobs includes a primary structured storage index for indexing Blobs, a secondary hash index that is integrated into the structured storage system, a Blob log stream, and a Blob data stream for storing blocks that include the Blob data. In an embodiment, a block is created and written to a Blob store along with a block list. The block list facilitates the locating of one or more blocks that store the Blob data. In this embodiment, a primary structured storage index and a secondary hash index are updated to facilitate efficient access of the Blob in a structured storage system.

  • Patent number: 8255373
    Abstract: Atomic multiple modifications of streams is provided. Streams are selected for the application of an atomic multiple modification. A lock is acquired on the meta-data associated with the streams. Each stream is de-coupled from its name. Multiple modifications are applied to the selected streams. After performing the modifications, names are coupled to the streams. The lock on the meta-data associated with each stream is released.
