A method includes receiving, at a first node of a plurality of nodes of a distributed database, an update request for an aggregate value stored at the first node. The update request includes a first sequencer. Based on receiving the update request for the aggregate value, the method includes updating the aggregate value based on the update request, storing a log record of the update to a changelog, and transmitting the update request to each other node. After updating the aggregate value, the method includes receiving, from a second node, a reset request for the aggregate value. The reset request includes a second sequencer. The method includes determining that the reset request predates the update request. Based on determining that the reset request predates the update request, the method includes resetting the aggregate value and updating the aggregate value based on the update request.
