Claim 13:
14. One or more non-transitory, computer-readable storage media, storing program instructions that when executed on or across one or more computing devices cause the one or more computing devices to implement:
receiving an update performed to a first data set stored in a first data store;
evaluating the update according to a schema for a second data set stored in a second data store that projects a subset of data from the first data set to the second data set, wherein the evaluation determines that the update is to be replicated to the second data set; and
sending a request to the second data store for conditional performance of 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.
