    Abstract: Techniques for backend-specific cursor tracking are described. In one embodiment, an apparatus may comprise a local database synchronization component operative to initiate a client update at a messaging client on a client device, the client update associated with a specific backend service for a messaging system; retrieve an opaque backend-specific update cursor for the specific backend service; and store an updated opaque backend-specific update cursor for the messaging client; and a local network component operative to send the opaque backend-specific update cursor to the messaging system in association with a client update request; and receive an update package at the messaging client on the client device, the update package comprising the updated opaque backend-specific update cursor. Other embodiments are described and claimed.

    Abstract: Techniques for database replication between client devices are described. In another embodiment, an apparatus may comprise a local database management component operative to send a collection subscription command from a client device to a database synchronization system, the collection subscription command specifying an object collection; and update a local database store for the object collection on the client device using a collection update; and a local queue component operative to receive the collection update from the database synchronization system based on the collection subscription command, the collection update for the object collection, the collection update received as a push notification from the database synchronization system; and send an update acknowledgement in response to the collection update based on the updating of the local database store for the object collection. Other embodiments are described and claimed.

    Abstract: Techniques for in-place directive execution are described. In one embodiment, an apparatus may comprise a local network component operative to receive a directive package at a messaging client on a client device, the directive package formatted according to a serialized directive schema; and store the directive package in a memory of the client device in the serialized directive schema; and a local database synchronization component operative to execute the directive package using in-place access of the directive package in the memory of the client device. Other embodiments are described and claimed.

    Abstract: Techniques for replication of a client database to remote devices are described. In one embodiment, an apparatus may comprise a server database management component operative to receive a collection subscription command from a client device at a database synchronization system, the collection subscription command specifying an object collection; and detect a collection change for the object collection; and an update queue management component operative to register the client device for push notification with a collection update queue associated with the object collection; and add a collection update to the collection update queue, the collection update based on the collection change. Other embodiments are described and claimed.
