Abstract
A database table may be synchronously replicated across regions of a provider network. When a write request to an item of the table is received at one region, a local version of the item may be obtained as well as any additional versions of the item corresponding to inflight writes that target the item from a multi-region replication append-only log. An updated version of the item is then generated based on the local version of the item and the additional versions, which is appended to the multi-region replication append-only log. A conditional write is performed to update the local version of the item with the updated version of the item. If successful, a response indicates that the write request was successful.
