Techniques for making eventual consistency cache updates deterministic. One technique includes receiving, at a control plane, a request to execute an operation on data, executing the operation on the data, creating a replication event for the operation and a replication identifier associated with the replication event, sending a response that includes a custom header having the replication identifier, receiving, at a data plane, a subsequent request to execute an operation involving the data, the subsequent request includes the replication identifier, retrieving a replication identifier for a latest replication event executed on the data plane, comparing the replication identifier from the subsequent request and the replication identifier for the latest replication event, determining the replication event associated with the replication identifier from the subsequent request has not been executed on the data plane based on the comparison, and sending a deterministic error message to the client device.
