THE YIN AND YANG OF MUTABILITY
by Péter Gömöri
THIS TALK IN THREE WORDS:
mutability
TALK LEVEL: Intermediate users
ABSTRACT
In the footsteps of Erik Stenman and Michal Muskala, let's explore another part of the BEAM VM. The two extremes of mutability: atomic counters and persistent terms were introduced without much ado, almost secretly in the patch release OTP 21.2. Via an example using them in an hdr histogram implementation, I'd like to explore their behaviour, caveats and limitations. And also show some benchmarks for scenarios when "you have to measure".
