Shanti Chellaram on Pri-Queue and raft_erl – Elixir Internals

Elixir Wizards

Today on the show we welcome Shanti Chellaram to talk about a couple of Erlang libraries she has created! We hear from her about Pri-Queue and raft_erl, and her motivation behind making them and some of the things we wishes she did differently! Shanti shares some of her background, early coding experiences, affinity for open source and her current work situation. From there we look at Pri-Queue, the problem it addresses and what a priority queue is. A highlight of the show is Shanti giving the best explanation of a bootstrapped skew binomial heap we have heard before explaining some of the main issues she faced in creating Pri-Queue. We then turn to raft_erl, how she got started with it and her hopes for its future. Throughout the conversation Shanti shares her philosophy towards open source and coding going forward as well as offering advice for newcomers to Erlang. Make you you join us for this fantastic episode!
