Appl. No.:

13/371123

Inventors:

Percy Mehta - Foster City CA, US
Jesse Collins - San Francisco CA, US
Kayvaan Ghassemieh - San Francisco CA, US

Assignee:

International Classification:

G06F 12/14
G06F 17/30

US Classification:

707785, 707E17005

Abstract:

The technology performs database access control in a manner that decreases computational cost of the database access control with an object type definition of a database object that permit multiple parent objects. The system determines whether to grant a user access to a database object via a first set of access control paths that do not rely on whether the user has permission to access a minimum number of parent objects of the database object. Responsive to a determination not to grant the user access via the first set of access control paths, the system determines whether to grant the user access to the database object via a second set of access control paths that determine whether the user has permission to access the minimum number of parent objects of the database object.

International Classification:

G06F 7/00

US Classification:

707608, 707E17044, 707E17055

Abstract:

A computer that is programmed with collaboration software receives a new value of an attribute (or property or characteristic) which is specific to a label (or tag or category) as applied to an object managed by the computer. The computer does not use the new value to overwrite a corresponding old value in existing metadata. Instead, the computer is programmed to hold the new value in an incremental label application for the object. The computer is further programmed to respond to a request for the object's label application, by retrieving the incremental label application, and a full application of said label to said object. The computer uses attribute values in the incremental label application to update corresponding attribute values in a copy of the full label application, in a time sequence based on the time of creation of incremental label applications, thereby to generate a current label application.

Johannes Kienzle - San Francisco CA, US

International Classification:

G06F 16/215
G06F 16/28
G06F 16/27

Abstract:

A method enables data aggregation in a multi-tenant system. The method includes receiving, at a data aggregation manager, an event from an activity tracking component, generating, by the data aggregation manager, a first hash value based on a first identifier in the event, generating, by the data aggregation manager, a second hash value based on a second identifier in the event, and storing event message information to an entry of a metric storage database in a partition according the first hash value and the second hash value.

G06F 9/54

Abstract:

A method and system of data deduplication for data streams in a multi-tenant system. The method receives, at a data accuracy manager, an event from an activity tracking component, determine whether the event is recorded in a probabilistic model that tracks previously received events from the activity tracking component, where the probabilistic model can accurately identify the event has not been previously received with a possible false positive response where the event has been previously received, determines whether information for the event is stored in a metric storage, where the metric storage is a database of metrics derived from the previously received events, and discards the event in response to determining that the event is recorded in the probabilistic model and in the metric storage.

International Classification:

G06F 16/2455
G06F 16/27

Abstract:

A method and system manage synchronization of data streams in a multi-tenant system. The method includes tracking by a flow control mechanism a recent flow rate of at least one data stream, determining by the flow control mechanism whether the flow rate of the at least one data stream varies from at least one related data stream, and adjusting by the flow control mechanism a throughput of the at least one data stream to correlate with the at least one related data stream, in response to determining that the at least one data stream has varied from the at least one related data stream.

Abstract:

A method and system that perform cluster node work assignments for tenants in a multi-tenant system. The method includes selecting a partition of a cluster tenant tracking structure having a hierarchical namespace and virtual nodes representing each tenant by a cluster node foreman controller, searching the selected partition for a tenant that is unlocked in the cluster tenant tracking structure, and initiating work for the tenant by the cluster node.

International Classification:

G06F 17/30

Abstract:

Methods, systems, and devices for asynchronous deletion at a non-relational database are described. The non-relational database may store a set of data object associations. The non-relational database may receive a read request indicating a first data object identifier. Based on the first data object identifier indicated in the read request, the non-relational database may identify a second data object identifier according to a first data object association of the stored set of data object associations that is indexed in the non-relational database with the first data object identifier. The non-relational database may determine that a last data entry that is indexed in the non-relational database with the identified second data object identifier and is associated with the first data object identifier has been deleted from the non-relational database. The non-relational database may delete the first data object association from the non-relational database.
