Abstract:In this paper, we target lookback processing systems (LPS), which allow queries to operate on segment-based historical data. We present new strategies that decide which segments should be placed, and how they should be replicated. Our approach leverages segment popularity. They are provably optimal in replication level, and thus memory and network overheads, for the static case. For the dynamic case, we present two heuristics. Our experiments show that the approaches improve memory and network utilization compared to existing strategies.
