  • Patent number: 10698920
    Abstract: Techniques are provided for a linearizable primary-secondary database system that replicates database data with eventual consistency. The techniques include obtaining a logical clock value of a logical clock that orders transactions committed at a primary database system that includes a primary database. The logical clock value is obtained after a write transaction is committed at the primary database system and while processing a read request. The logical clock value is used to determine whether a secondary database is in a consistent replication state corresponding to the logical clock value with respect to the primary database. The read request is maintained in a linger state while the secondary database is not yet in the consistent replication state. The read request exits the linger state and is allowed to be processed against the secondary database after the secondary database has reached the consistent replication state.

  • Patent number: 10542092
    Abstract: A content management system for collecting files from one or more submitters in a collection folder. A collector, who generates the collection folder, can invite one or more submitters to submit one or more files to the collection folder. The one or more submitters have limited rights to the collection folder. The limited rights can include uploading rights and prohibiting a submitter from viewing files that other submitters associated with the collection folder submitted. Thus, the collection folder is able to store files from the one or more submitters, but prevent them from viewing other's submissions.
