Scale By The Bay 2018: Pathikrit Bhowmick, ArrayDeques and How to Contribute to Scala 2.13

ai.bythebay.io Nov 2025, Oakland, full-stack AI conference Scale By the Bay 2019 is held on November 13-15 in sunny Oakland, California, on the shores of Lake Merritt: https://scale.bythebay.io. Join us! ----- In this talk, we will introduce a new data structure, mutable.ArrayDeque, that outperforms most current mutable Scala collections like Lists, Buffers, Stacks and Queues. We will also go over implementation details needed for this to be part of the new Scala 2.13 collections library. We will then encourage the audience to contribute other useful data structures like Ropes, Zippers, Disjoint Sets etc. to Scala.
