ABC: A practicable sketch framework for non-uniform multisets

SALSA: Self-Adjusting Lean Streaming Analytics

“…Using different workloads, metrics, and tasks, we also show significant accuracy improvements for the above schemes as well as for state of the art solutions like Univmon [15], Cold Filter [9], and AEE [16]. We also compare against Pyramid Sketch [12] and ABC [17], recent variable-counter-size solutions, and show that SALSA is more accurate than both. Finally, we release our code as open source [1].…”

“…Such settings are standard for applications that aim for speed rather than being memoryoptimal. For the ABC [17] and Pyramid [12] sketches, as well as the Cold Filter [9] framework, we use the configurations recommended by the authors. We pick s = 8 bit counters as the default configuration of SALSA, motivated by the synthetic results.…”

“…Most relevant to our setting are ABC [17] and Pyramid Sketch [12], which vary the size of counters on the fly. In ABC, an overflowing counter is allowed to "borrow" bits from the next counter.…”

“…We also extend these to create a Baseline and SALSA implementation of CS. We also used the authors' code for the Pyramid [12], ABC [17], and Cold Filter [9] algorithms. Particularly, for error measurements, we used the code as-is, while for speed measurements, we applied our optimizations for a fair comparison.…”

“…Further, Tango has an overhead of 1 bit per counter and does not obviously allow an efficient Fig. 8: Comparing the performance of the SALSA, Pyramid [12], ABC [17], and Baseline versions of CMS. encoding like SALSA does (Section IV).…”
