Database replication is provided by accessing, by a subscribing application, a message queue through a messaging queue manager. The subscribing application obtains a message provided by a publishing application from the message queue. The message includes message data that corresponds to shard data in a shard database. The subscribing application then provides the message data included in the message to a de-shard database as de-shard data. The de-shard data is an instance of the shard data and is modifiable by the subscribing application without changing the shard data.
