Use Eclipse Collections

[koppor]

Context: #2837, #2533, #2247

Eclipse Collections seem to be be more memory efficient than standard Java Implementations.

Should we try to switch to Eclipse Collections?

I would vote against switching as we then heavily depend on an external library for core features and switching back would be a problem then. Am 18.07.2017 10:55 vorm. schrieb "Oliver Kopp" <notifications@github.com>:

Fir the first months, I would just use their implementations and rely on the normal Java interfaces. (Is that item 18 of Effective Java?)

Thus, it would be "just" another dependency. 😇

We are currently trying to focus on other things. 🔥
We will come back later to this topic, therefore closing adding on-hold label and closing the issue for now.
