Disclosed herein are system, method, and device embodiments for optimizing uploads for an offline scenario by merging requests. An embodiment operates by performing a plurality of modification operations over application storage, generating a first queue entry within a normal operations queue corresponding to a first modification operation of the plurality of modification operations, generating a second queue entry corresponding to a second modification operation of the plurality of modification operations, generating an optimized operations queue including an optimized queue entry combining the first queue entry and the second queue entry, and synchronizing the application storage with a remote storage system based on the optimized operations queue.

Optimizing uploads for an offline scenario by merging modification operations

Guaranteed message sequencing between a first and second database is described. An example method includes maintaining first state information associated with the first database at the first database, where second state information associated with the first database is maintained at the second database. The client sends, to the second database, a message describing changed rows between the first database and the second database since a last synchronization and the first state information. The client subsequently receives, from the second database, status of the last synchronization, where the status is determined by the second database based on the first state information and the second state information.

Robust communication system for guaranteed message sequencing with the detection of duplicate senders

Systems, methods and computer program products for maintaining data integrity in a database environment are described. In operation, a synchronization process is initiated in a remote database system for synchronization of remote data from the remote database system with consolidated data of a consolidated database. Metadata for each row of the remote data is utilized to allow transactional access to the remote data while the synchronization process occurs.
