[Syscussion] Next syscussion: MacroBase: Prioritizing Attention in Fast Data

[Giannis Giannakopoulos]

Καλησπέρα,

το επόμενο syscussion θα πραγματοποιηθεί Παρασκευή 2/2 στη 1μμ. Μετά από
λαϊκή απαίτηση να *μην αφορά* optimization πρόβλημα, το paper που θα
παρουσιάσω είναι το εξής:

*Title:* MacroBase: Prioritizing Attention in Fast Data
*Authors:* Peter Bailis, Edward Gan, Samuel Madden, Deepak Narayanan, Kexin
Rong, Sahaana Suri
*Abstract:* As data volumes continue to rise, manual inspection is becoming
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.
