increasingly untenable. In response, we present MacroBase, a data
analytics engine that prioritizes end-user attention in high-volume
fast data streams. MacroBase enables efficient, accurate, and modular
analyses that highlight and aggregate important and unusual
behavior, acting as a search engine for fast data. MacroBase is
able to deliver order-of-magnitude speedups over alternatives by
optimizing the combination of explanation and classification tasks
and by leveraging a new reservoir sampler and heavy-hitters sketch
specialized for fast data streams. As a result, MacroBase delivers
accurate results at speeds of up to 2M events per second per query
on a single core. The system has delivered meaningful results in
production, including at a telematics company monitoring hundreds
of thousands of vehicles.</div><div><br></div><div>Δημιοσιευμένο στο SIGMOD 2017.</div><div><br></div><div>Γιάννης</div></div>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div class="inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-b5 inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-xJNT8d" style="font-family:sans-serif;overflow-x:auto;overflow-y:hidden;padding-left:10px;margin-right:60px"><div class="inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-uyb8Gf"><div><div class="inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-F3hlO"><div class="gmail_extra"><div class="inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-inbox-m_-2227816469423682111gmail_signature"><div dir="ltr"><pre cols="72"><font face="arial, helvetica, sans-serif">Ioannis Giannakopoulos
