Claim 15:
16. The one or more non-transitory, computer-readable storage media of claim 14, storing further program instructions that when executed on or across the one or more computing devices, cause the one or more computing devices to further implement:
receiving, at the first database node, a different read request directed to the database data;
determining, by the first database node, that a second MVCC snapshot time determined for the different read request is greater than the point in time of the consistency lease;
returning, by the first database node, a failure indication for the different read request after the first database node fails to obtain an updated consistency lease with an updated point in time that is greater than the MVCC snapshot time for the different read request.
