Abstract
Storing data records within a log data store is provided. The log data store that stores data records within a plurality of successive non-disjoint layers inserted across a plurality of different types of data storage devices associated with a data processing system is generated. A first non-disjoint layer of the plurality of successive non-disjoint layers is inserted within a main memory device. A set of intermediate non-disjoint layers of the plurality of successive non-disjoint layers is inserted within a set of storage-class memory devices. A last non-disjoint layer of the plurality of successive non-disjoint layers is inserted within a hard disk drive. A size of each successive non-disjoint layer in the plurality of successive non-disjoint layers is increased exponentially. The data records are organized into the plurality of successive non-disjoint layers of the log data store inserted across the plurality of different types of data storage devices.
