Abstract
Disclosed are various embodiments for employing spillover tables to improve performance of data store updates. A request to update a data field is received, and if an exclusive lock on a data table cannot be obtained, the request is placed in a spillover table until the exclusive lock can be obtained. If the request causes a constraint on the data field to be violated or causes the data field to move closer to the constraint, the request is not placed in the spillover table. A spillover task can collapse entries in the spillover table into the data store when an exclusive lock can be obtained.
