Hi, I'm currently working on some code in Flink's runtime and want to use some Java Primitive Collections to improve performance.
As fas as I can see no Primitive Collections library is in the dependencies so I wanted to ask if anybody has any preferences or input on which library the project should use. The viable candidates (from a licensing perspective at least) are: - Apache Commons Primitives Collections - High Performance Primitives Collections for Java (HPPC) - fastutil They are all APL 2.0 licensed. Since I'm probably not the only one who is going to use Primitive Collections I don't want to introduce a new dependency without any discussion. Cheers, Robert
