Claim 4:
5. A method, comprising:
obtaining an update performed to a first data set stored in a first data store;
determining that the update to the first data set is to be replicated to a second data set stored in a second data store according to a schema for the second data set that projects a subset of data from the first data set to the second data set; and
sending a request to conditionally perform the update to the second data set at the second data store, wherein the request specifies a second version identifier, wherein the update is performed by the second data store after a comparison of a first version identifier associated with the update and the second version identifier associated with the second data set indicates that performance of the update is consistent with a sequential ordering of different updates performed to the first data set, and wherein a given update is not performed after a comparison indicates that the given update is not consistent with the sequential ordering of different updates performed to the database.
