Managing large state on the Beam

Jun 29, 2017 · San Francisco, United States of America

Come hear Yoshihiro Tanaka talk about state on the Beam and learn what OpenX is doing with Erlang!

OpenX has developed an Erlang powered integrated technology platform that combines ad server and a real-time bidding exchange with a standard supply-side platform ensuring the highest real-time value for any trade. OpenX was founded in 2008 and has raised over $75 million from Accel, Index,  Samsung,  Dentsu,  Mangrove Capital and others.

Abstract: Erlang's process model is shared-nothing, and processes communicate over message passing. This gives us challenges when we have large amount of state on the Erlang VM. In his talk, Yoshi will share the experience how OpenX dealt with this problem and improved performance. This talk will be beneficial for Elixir users too since this is regarding the behavior of Erlang VM.

This talk will include:

1. Erlang process structure
2. When data is copied
3. What is constant pool and what is the benefit of using it
4. Use cases at OpenX

Bio: Yoshihiro joined OpenX in 2011 and engaged in various Erlang components design/development including market qualification engine, data service, server-side real-time bidding system, and their DSL library. He is the Erlang lead developer in their Santa Clara office.
