Synchronizing document replication in distributed systems

A method comprising:

• generating, by a controller, a first proxy object for a first document at a first system, the first system including the controller and the first proxy object;
• updating, by the controller, the first proxy object to include a replication status of the first document, when a creation, an update, and/or a deletion occurs at the first document;
• receiving, at the first proxy object, a query for the replication status;
• sending, by the first proxy object, at least a portion of the first document to a target system to replicate at least the portion of the first document at the target system, when the replication status indicates the first document is not in synchronization with the target system due to the creation, the update, and/or the deletion;
• receiving, at the source system, a confirmation message indicating a successful replication of at least the portion of the first document at the target system;
• and
• updating, in response to the confirmation message, the first proxy object to reflect that the source system and the target system are in synchronization with respect to the first document.

A non-transitory computer-readable storage medium including program code which when executed by at least one processor causes operations comprising:

• generating, by a controller, a first proxy object for a first document at a first system, the first system including the controller and the first proxy object;
• updating, by the controller, the first proxy object to include a replication status of the first document, when a creation, an update, and/or a deletion occurs at the first document;
• receiving, at the first proxy object, a query for the replication status;
• sending, by the first proxy object, at least a portion of the first document to a target system to replicate at least the portion of the first document at the target system, when the replication status indicates the first document is not in synchronization with the target system due to the creation, the update, and/or the deletion;
• receiving, at the source system, a confirmation message indicating a successful replication of at least the portion of the first document at the target system;
• and
• updating, in response to the confirmation message, the first proxy object to reflect that the source system and the target system are in synchronization with respect to the first document.
