Abstract: Techniques for messaging using replication of a client database are described. In one embodiment, an apparatus may comprise a local queue component operative to receive a message collection update at the first client device from a database synchronization system via an update queue, the message collection update for a message object collection, the message object collection associated with device-to-device messaging communication between the first client device and a second client device; and a local database management component operative to update a local database store for the message object collection on the client device using the message collection update, wherein updating the local database store is based on a collection identifier for the message collection update; and extract a device-to-device message from the message collection update, wherein extracting the device-to-device message from the message collection update empowers the messaging client to display the device-to-device message on the first client device. Other embodiments are described and claimed.
