To Share, or not to Share Online Event Trend Aggregation Over Bursty Event Streams

Summary: Hamlet enables adaptive runtime sharing for Kleene-pattern trend queries on streams. It makes run-time share/no-share decisions and uses a fast shared trend-aggregation that avoids trend construction, achieving up to 1e5x latency reduction vs prior art.
