PR-Sketch: Monitoring Per-key Aggregation of Streaming Data with Nearly Full Accuracy
Summary: PR-Sketch delivers nearly full-accuracy per-key streaming aggregation under bounded resources. It ties counters to per-key values via linear equations and records keys in the recovery phase to reduce update cost, with a fast variant and trace-driven validation of efficiency and accuracy.
