Adaptable query accuracy at scale a talk by Alberto Schiabel

Friday 15 September 15:00 (30 minutes)

Have you ever wondered how social medias keep track of the number of likes and comments under each post? In a distributed world, performing accurate and fast queries on large amounts of data is challenging, as traditional query techniques can become impractical at scale.

Thankfully, probabilistic techniques allow us to trade a small amount of accuracy for significant performance gains. Introducing data structures like Bloom filters and Count-Min sketches, we’ll develop an intuition on how they are used for efficient set membership or frequency queries, and will compare their performance with non-probabilistic queries. We will also compare probabilistic data structures coded in Python with real-world alternatives used in databases.

After this talk, you will have a better understanding of the internals of popular databases and new tools at your disposal to let your software service grow at scale.
