A data-store management apparatus includes a storage unit, a communication unit, and a processor. The storage unit holds response speed information indicating a response speed of each of data stores. The communication unit receives a subscribe request for requesting subscription of a topic updated by an update-side apparatus. The subscribe request includes communication speed information indicating a first communication speed of a first terminal that has transmitted the subscribe request. The processor identifies a first data store, among the data stores, that has a response speed higher than or equal to the first communication speed on the basis of the communication speed information included in the subscribe request and the response speed information. The processor causes the first data store to store the topic. The processor causes the first data store to respond to a read request for the topic. The read request has been transmitted from the first terminal. |
