ELIXIR After 2 years in action and some code example Elixir WebUp September Zilina https://github.com/payout-one/webup_september
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
