    Self-Tuning for Short-Term Memory Consumers
    (Datenbank-Spektrum: Vol. 11, No. 1, 2011) Overbeck, Ludger C.; Schmidt, Karsten
    We present an approach to adequately consider short-term memory consumers when using self-tuning buffer techniques. For instance, sort operations often need (large) amounts of memory but only for a short time. Moreover, certain operators, e.g., joins, require (lots of) memory to produce results that are retrieved only once. Unfortunately, most traditional self-tuning techniques fail to observe those peaks, as they need to monitor a system for a while before tuning it, which is often too late.
