Abstract: Methods, systems, and computer-readable media for versioned metadata management for a time-series database are disclosed. A metadata service of a distributed time-series database stores, to one or more metadata storage resources, first metadata descriptive of a table. The first metadata is associated with a version number in a logical sequence for the table. The metadata service stores, in a log, data indicative of one or more metadata updates for the table. The metadata update(s) are associated with an additional version number higher than the version number in the logical sequence. Responsive to a read request, the metadata service determines a most recent version number that has been applied from the log to the metadata storage resource(s). Responsive to the read request and based (at least in part) on the most recent version number, the metadata service returns either the first metadata or second metadata comprising the update(s).

Abstract: A Privacy Controlled Social Network including a first device that shares content with a second device through at least one network, where content is “encoded” or “locked” at the first device by applying a locking code. In embodiments, the locked content that is shared may include media that is locked by applying the locking code at the first device. The locked content may be shared with the second device and include a message or caption that is not locked and viewable by the recipient user of the second device. The locked content may be unlocked by providing the appropriate code to a user interface to unlock the content for the user of the second device. A lock/unlock scheme using input related to a display of an item associated with the content to lock/unlock the content may utilize gestures on a touch screen displaying the item as the lock/unlock code.
