Big Data with Elixir

What about a project that isn’t quite a “Big Data” project? Rather a Medium Data project - if you will.

Like an ETL / Data Warehousing project that required data to be collected from a dozen data sources that in total are not quite in PB territory. With Elixir it would be fairly straightforward to write an app that queries and processes the data sources concurrently. There would certainly be some number crunching involved but nothing at a scale that justifies building a Hadoop cluster.

Would the issues discussed on here about Elixir/Erlang’s weak spots in the number crunching arena be problematic at this “Medium Data” scale?
