Subject Re: Java Driver 3.0 for Apache Cassandra - Documentation Outdated?
Date Mon, 06 Jun 2016 23:57:33 GMT
I think it comes down to having full time tech writers employed and paid. If Datastax has the
$$ to provide a significant benefit to the community (well thought out documentation) that's
better than little or no documentation (if it was only done via developers who most likely
won't document or do a poor job at documentation).

Having some documentation is much better for the community than the alternative that "the
code is the documentation".

Nothing is free.

Excellent, why am I the first person to ask that, and why didn’t
a PMC member point that out right away and why did it take me asking
to point to the Apache docs.

This is what I am talking about in terms of the Apache community..

So, the core documentation for a key part of Cassandra is hosted
at DataStax?

I was checking the documentation for TupleType in DataStax docs here
the code example was like this:

TupleType theType = TupleType.of(DataType.cint(), DataType.text(),

But in the code, the *TupleType.of* has two additional parameters not
mentioned in the documentation:

*public static TupleType of(ProtocolVersion protocolVersion, CodecRegistry
codecRegistry, DataType... types)*

Maybe I am looking in the wrong place. Could someone please explain how can
I instantiate a *TupleType*?

I have the same question for *Map* type.

Thanks for your help.

Best Regards
