Hi Kenneth, As a Cassandra user I value usability, but since it's a database I value consistency and performance even more. If you want usability and documentation you can use Datastax DSE, after all that's where they add value on top of Cassandra. Since Datastax actually paid dev to work Cassandra internals, it's understandable that they kept some part (usability) for their own product. We all notice that when you google for some CQL commands you'll always end up to Datastax site, it would be great if that was not the case but it would take a lot of time.
Also, as a manager you're not supposed to fight with devs but to allocate tasks/time. If you have to choose between enhancing documentation and fixing this bad race condition that corrupts data, I hope you'd choose the later. As for filling Jiras, if you create one like "I want a UI to setup TLS" it would be the kind of Jira nobody would implement, it takes a lot of time, touches security and may not be that useful in the end. Last point on usability for Cassandra, as an end user it's very difficult to see the progress on it, but since I'm using Cassandra internals for my custom secondary index I can tell you that there was a huge rework between Cassandra 2.2 and 3.x, PartitionIterators are a very elegant solution and is really helpful in my case, great work guys :) -- Jacques-Henri Berthemet -----Original Message----- From: Kenneth Brotman [mailto:kenbrot...@yahoo.com.INVALID] Sent: Wednesday, February 21, 2018 11:54 PM To: dev@cassandra.apache.org Cc: u...@cassandra.apache.org Subject: RE: Cassandra Needs to Grow Up by Version Five! Hi Akash, I get the part about outside work which is why in replying to Jeff Jirsa I was suggesting the big companies could justify taking it on easy enough and you know actually pay the people who would be working at it so those people could have a life. The part I don't get is the aversion to usability. Isn't that what you think about when you are coding? "Am I making this thing I'm building easy to use?" If you were programming for me, we would be constantly talking about what we are building and how we can make things easier for users. If I had to fight with a developer, architect or engineer about usability all the time, they would be gone and quick. How do approach programming if you aren't trying to make things easy.

I would second Jon in the arguments he made. Contributing outside work is draining and really requires a lot of commitment. If someone requires features around usability etc, just pay for it, period.
