Download as PPTX, PDF0 likes487 views
The document discusses the use of Elixir and its benefits in application development, focusing on performance, fault tolerance, and the comparison with Erlang. It covers the start of projects using Elixir, GenServer behavior, and optimization through various strategies. Additionally, it provides resources for further learning and showcases code examples relevant to handling large data sets effectively.
Elixir - After 2 years in action + code WebUp
- 1. Better way to pay ELIXIR After 2 years in action Oliver Payout CTO Sept 2019
- 3. All Team !!! <3 :-) There is something missing!!!
- 4. Oliver, what about performance? Peter Payout founder 10k transactions/sec Scaling everywhere No Limits We believe what we do and how we do it
- 5. Oliver, which technologies we use? .NET 😂😂😂😂 It’s hardcoded
- 6. Payout 2017 Elixir since 2017 Ruby since 2010 Intro - Oliver
- 7. Current version 1.9.1 (July 2019) Since 2011 Based on BEAM (1982-1991 …) Supported by Plataformatec 811 contributors > 15k commits Intro - Elixir Forum ~ 12k topics ~10k users (2.5k active) Slack > 22k users
- 8. Current version 1.4.10 (Sept 2019) Since 2014 693 contributors > 5k commits Intro - Phoenix Supported by Plataformatec Plug vs Middleware(Rails)
- 9. Why Erlang Erlang ● First choice 🤯 ● + Partner companies use it ● + OTP (Fault tolerance) ● + In production for decades ● + Still active and progressive ● + Speed ● - Learning curve ● - Syntax
- 10. Why Elixir Elixir ● Second choice ● + Erlang ● + Syntax ● + Syntax similar to Ruby ● + Learning curve ● + Phoenix ● - “Young” language ● - OOP -> FP ● - New Environment (Docker, …)
- 11. How we started Rails developers Minimal FP skills First touch with - Elixir, - Erlang, - Hex, - Docker - ...
- 12. What about YOU? “Fears are nothing more than a state of mind.” —Napoleon Hill
- 13. Multiple Processes GenServers everywhere? More |> (pipe operator) Multiple applications Cluster Some advise Own packages More modular Lost focus to Phoenix Phoenix LiveView more
- 14. Let’s see some code
- 15. GenServer Client - Server Behaviour Supervised One process Synch/Async Messaging State
- 16. GenServer Very fast State in Memory Bottleneck Simple Queue - Timeout No concurrency Solutions - Pool boy - DynamicSupervisor - Task.async
- 17. GenServer Very fast State in Memory Bottleneck Simple Queue - Timeout No concurrency More Solutions - Pool boy - DynamicSupervisor - Task.async
- 18. Some hints Pattern match in functions Tuple return - fault tolerance flow
- 21. Stream lazy enumerables lazy operations future computations More Flow GenStage computations on collections similar to Stream More
- 22. Let’s see some code
