Abstract: Disclosed herein are system, method, and computer program product embodiments for synchronizing an unsynchronized distributed database system. An embodiment operates by locking, by a second node, partitions in the second node based on first information received from, a first node responsive to execution of partition utility based on a first query received by the first node. Blocking, by the second node, a second query to a data portion of the partitions in the second node based on the first information. Locking, by the second node, second node object metadata based on second information received from the first node. Receiving, by the second node, changes to first node object metadata and applying the changes to the second node object metadata. Unlocking, by the second node, the partitions in the second node and the second node object metadata while unblocking the second query.
