Subject Re: Suggest improvement to Util classes (Ignite ML)
Date Wed, 26 Aug 2020 13:21:01 GMT
Hi, Mark, it's great to hear from you a few suggestions related to code
culture and so on.
I hope during PR preparation it will be more of them and I suggest to
collect them in the shared doc (i've added first two of them)

When we collect a few suggestions there I'll promise to spend time to solve
each incident to answer you or create a ticket or quick fix.
Also we could arrange a call in the next few weeks to answer your questions
and discuss your suggestions.

> Hence, at least one non-public constructor should be defined.

> - IgniteModelStorageUtil.java
> - MapUtil.java
> - MatrixUtil.java
> - Utils.java
> Class JdbcThinSSLUtil.java already has a private constructor.
