Re: NewBie Question

For newcomers that ( https://github.com/apache/cassandra/blob/cassandra-3.0.0/guide_8099.md) is probably a bad document to point them to, as it will no doubt confuse them - the naming, behaviour and format descriptions are all now partially incorrect. It was, by its own admission, intended only

Since the specs change with the code id argue everything belongs in the git repo including deep technical specs. On Wed, Jun 15, 2016 at 10:26 AM J. D. Jordan wrote: > I think high level concepts of how data is stored should be in user facing > documentation. Storage

I agree that it should be documented but I don't think it should be in user level docs. Let's keep it in the wiki for contributors. On Jun 15, 2016 7:04 PM, "Jonathan Haddad" wrote: > Definitely required reading for anyone getting into it, plus Aaron's post. > I think ideally

Re: NewBie Question

The file format is SSTable: http://wiki.apache.org/cassandra/ArchitectureSSTable If you're getting into byte-level detail, I highly recommend you familiarize yourself with the read and/or write path first, because that deep in the bowels there are some non-obvious things going on where Cassandra

Re: NewBie Question

It's a little more involved than that. I suggest inserting a single row in a test table, then looking at the sstabledump output as a first step, then compare with two rows in a single partition. Then you can code dive to see what sstabledump is actually doing if you really need the byte-level

Hi Matt, I suggested the resources keeping in mind the ease with which one can learn. My idea was not to disrespect Apache or community in any form, it was just to facilitate learning of a Newbie. While having a good wiki would be amazing and I believe we all agree on this Thread that current

Hi Chris, Disclaimer: I am a Datastax employee It is clear to me that the current official documentation is far from being enough. That's why I fully support the decision made by Jonathan to do our best to improve it. As an Apache Cassandra Committer mostly working on the CQL layer, I know that

Hi Harmeet, The dev list is the lifeblood of an Apache project, and projects here at the ASF conduct 99% of their business in public, not in private. The ASF is a non-profit for the public good and we have a tradition of openness and transparency. Even if the business isn’t pleasant some

Re: NewBie Question ~ Book for Cassandra

It's really not open to debate that the Project needs to provide adequate documentation. We have dropped the ball on this as a community since Moin became unusable, but we are now coordinating the replacement on CASSANDRA-8700 and should have a first version as soon as a week from now. There is

Re: NewBie Question ~ Book for Cassandra

I respectfully disagree. "Newbies" should be pointed in the direction that will ensure the highest possibility of their success with the product. This is the best decision for the project, regardless of where the documentation may reside. As one of the authors of an early book on Cassandra, the

Chris, The tools supplied by Apache for documentation, ie, wiki, are awful. No human being should be subjected to those. It would be great if someone of your stature would do something about that for the entire Apache community. On 06/11/2016 12:16 PM, Mattmann, Chris A (3980) wrote: Hi
