lean-map

The talk at Clojure West wasn't given by myself, but I found it worthwhile linking. Rather it was given by someone who independently picked up my research results and replicated them in the context of ClojureScript (https://github.com/bendyworks/lean-map). The authors independently confirmed the performance improvements of CHAMP over HAMT that I was observing. You can also have a look at the JVMLS'16 talk (https://www.youtube.com/watch?v=pUXeNAeyY34) for a high-level overview of the work that is covered in my thesis.

Adoption (especially in industry) takes time, but there's definitely interest in the Clojure and Scala communities. The CHAMP data structure was already picked up by the ClojureScript community (https://github.com/bendyworks/lean-map), but still requires some work to be upstreamed to Clojure I guess. I personally (I'm the author of the thesis linked above) plan to work together with the Scala folks at Lightbend for the collections overhaul that's planned for Scala 2.13 (see https://github.com/scala/collection-strawman).
