Abstract
This paper presents on-line algorithm that determines further datapath for incoming requests - should they temporarily stay in RAM buffers for future merge operation or should they be written to disks immediately. With workload analysis in real time, the delay time spent in RAM buffer is a self-tuned parameter. This approach increases sequential write requests latency but sufficiently raises the overall performance of sequential write workloads without the use of expensive non-volatile cache.
