Two extreme resolution of consistency: one is to reconcile each copy before it is actually written, to ensure that no conflicts occur, and to merge conflicting writes so that any copy can write data.4 combination of sharding and replicationidea: The data is fragmented first, and then for each piece of data are "master-slave Replication" for maintenance, which means that there are multiple primary nodes in the system, for each data, the main node responsible for it only one.
