  • Patent number: 10936538
    Abstract: Embodiments are directed to managing data in a file system. A query may be provided to determine characteristics associated with a file system and a sampling model. The sampling model may be employed to determine objects in the file system based on a traversal of the file system. The sampling model may be employed to determine metrics associated with the alternate data streams (ADSs) included in the objects such that each of the objects that includes a separate main data stream and the ADSs may be associated with data blocks and the ADSs may each be associated with other data blocks. The sampling model and the query may be employed to sample the objects to provide partial results such that the sampling may be distributed between the objects based on the sampling model and the metrics. A result to the query may be provided based on the partial results.

  • Patent number: 10936551
    Abstract: Embodiments are direct to managing file systems. Alternate data streams (ADSs) of an object in a file system may be modified based on a request from a client and metrics associated with the ADSs may be modified. Values for reconcile fields associated with the object may be set based on the modified metrics such that the object with the modified ADSs may be included in a reconcile list. And, such that an acknowledgment of the request may be provided to the client. A reconcile engine may determine a parent object of the object. The object may be reconciled and the parent object may be placed on the reconcile list for reconciling in turn.
