Conference Schedule - FOSDEM PGDay 2020

PostgreSQL vs. probabilistic data structures

Date: 2020-01-31
Time: 10:20 - 11:10
Room: PGDay at Hilton

This talk is primarily about t-digest and q-digest, two interesting probabilistic data structures allowing efficient (distributed, parallel) estimation of rank-based statistics (e.g. percentiles). I'll briefly explain the purpose, basic principles and how you can use them to process large amounts of data in PostgreSQL.
