Abstract: A data storing control apparatus includes a processor. The processor executes a process including: selecting any of groups stored in a second storage unit when an empty space of the second storage unit configured to store data obtained from a first storage unit becomes insufficient; partitioning the selected group in accordance with a state of access to data corresponding to a data access request in the second storage unit among data included in the selected group; and storing data respectively included in the groups in the first storage unit in units of the groups obtained by being partitioned.

Abstract: A computer acquires a particular entry(ies) from a database that includes plural entries for each of which a key is determined; stores the particular entry(ies) into a memory provided in the computer and used as one of memories that store the database in a distributed manner; and associates a particular piece of communication endpoint information with a network interface of the computer. Each key for each particular entry belongs to a particular subset among mutually disjoint subsets of a domain of keys. The particular piece of the communication endpoint information is one of a predetermined number of pieces of the communication endpoint information and is associated with the particular subset. Each piece of the communication endpoint information logically identifies one communication endpoint, is dynamically associated with one network interface which provides access to one of the memories, and is statically associated with one of the subsets.
