I&#x27;m currently working at implementing all types of ETL &amp; data extraction processes with Elixir, and so far I must say I like this (although I cannot share numbers are the moment, just yet).<p>My own impression (as the author of <a href="http:&#x2F;&#x2F;www.kiba-etl.org" rel="nofollow">http:&#x2F;&#x2F;www.kiba-etl.org</a> which is a Ruby ETL framework) is that Elixir is going to be a great fit for high-quality, decent throughput data processing of all kinds (streaming, batching, or other such as websocket-api-endpoint types).<p>The immutable data + lightweight processes + ability to go distributed + concise code (testable, composable etc) is truly appealing in my opinion.<p>I will share more stuff online (at <a href="http:&#x2F;&#x2F;thibautbarrere.com" rel="nofollow">http:&#x2F;&#x2F;thibautbarrere.com</a>) when I can, but I can only say this is so far very promising.
