With multi-Region eventual consistency (MREC), the default mode, item changes are replicated to the other replicas typically within a second and are eventually consistent across Regions. With multi-Region strong consistency (MRSC), item changes are synchronously replicated to another Region before the write returns, and strongly consistent read operations on any replica always return the latest version of an item.
