State-of-the-Art Analytical Systems in Elixir

In this talk, Dmitry Russ, a lead engineer at Uepn, shares his experience on developing analytical systems with Elixir presented at Code BEAM Europe 2023. The talk covers their work on Process Mining products over several years, leveraging various technologies such as Clickhouse, MariaDB, DuckDB, KDB+, and Polars. Dmitry highlights the problems, design decisions, and challenges faced during the development process, including the creation of an in-house Ecto-like framework. He discusses the limitations of SQL for certain tasks and emphasizes the need for lower-level technologies like Polars and KDB+. The talk concludes with examples comparing functionalities of Elixir Explorer and Python, offering practical insights into the state-of-the-art techniques in Elixir for analytical systems.
