Hello,
quick learning question. Does Scala automatically use the Linux DNS cache services like nscd?
In practice, “Scala”* reuses Java libraries for low-level network operation. I’d expect Java libraries to do the right thing—IIRC, nscd should not require much special support. Googling finds next to no info on the topic, suggesting nobody had issues (https://stackoverflow.com/a/2291815/53974 confirms Java was using nscd for this user).
*To be sure, “Scala” the language has nothing to do with this, and while most libraries reuse Java services, nothing forbids anybody from writing (in Scala or Java) their own nscd-bypassing DNS client.
