Abstract
A method of reducing write amplification in an append-only memory store of data records, by which the store is subdivided into streams, each of which for storing records having an update frequency within a variable range of update frequencies. By defining an update frequency that does not rely on time, statistical methods can be used to select the streams in which data records can be written. The range of update frequencies of each stream can be fixed or variable and based on the stored records. The memory allocated to each stream can be determined based on numerically solving an optimization problem that determines the write amplification resulting from different memory allocations in the streams.
