Abstract: In general, metadata is stored in a data storage system. Summary data identifying one or more characteristics of each of multiple metadata objects stored in the data storage system is computed, and the summary data characterizing a given metadata object in association with the given metadata object is stored. A visual representation is generated of a diagram including nodes representing respective metadata objects and relationships among the nodes. Generating the visual representation includes superimposing a representation of a characteristic identified by the summary data characterizing a given metadata object in proximity to the node representing the given metadata object.

Abstract: A data sync cache is maintained to facilitate syncing of child data objects between a first computing system and a second computing system. Responsive to successful syncing of a parent data object of a child data object by a first sync engine, parent object data sync information indicating that the parent data object was successfully synced is written to the data sync cache. Prior to initiating a sync of the child data object by a second sync engine different from the first sync engine, a cache lookup of the data sync cache is performed to determine if the sync information is contained therein. If the data sync cache includes the sync information, the child data object sync is initiated. In this manner, failed syncs of child data objects are reduced along with the expensive API calls to the second computing system that would otherwise be required to retry failed syncs.

The database transaction is then compared to another database transaction based on its timestamp. Based on the comparison, either the database transaction for the lost change resynchronization operation or the other database transaction is executed.

Abstract: A content management system implementing methodologies providing retroactive shared content item links is disclosed. The content management system and methodologies allow a team administrator of a team to configure a team-wide shared link policy that determines whether non-team members can access content items associated with team accounts using shared links generated for the content items by team members.

In a second setting, the content management system blocks access to the content items by non-team members. Shared links are retroactive in the sense they do not need to be regenerated after the team shared link policy has been changed from the second setting back to the first setting.

Abstract: A technique for synchronizing a datum between a plurality of stores, wherein a version history is associated with the datum in each store. The version history has one or more entries, and each entry has an identifier and a value. The identifier identifies a store that has modified the datum, and indicates a number of modifications to the datum. When synchronizing the datum between stores, the version histories of the datum are compared to determine whether one version history is subordinate to another version history. The datum having the subordinate version history is then replaced with the datum having the dominant version history. Conflict resolution is required if the version histories are not identical, if the version histories do not have the same identifiers, and if one version history does not contain all of the identifiers with equal or greater values of those in the other version history.

Each system includes a main table, multisite table(s) and replication trigger logic. A multisite table corresponds to a main table of another system. When a main table of a system is changed, in response to an input, the system generates and sends replication transactions to the other systems for changing main tables in the other systems. In accordance with the change specified in the replication transaction, the multisite tables are modified. In each system, the replication trigger logic determines whether or not to replicate the change specified in the replication transaction to the main table of the each system, upon application of the replication trigger logic to the replication transaction. The change specified in the replication transaction may relate to inserting, deleting, or updating a record in the main table.
