Scalable PHP web applications with Apache Cassandra

I missed the base principle of cassandra

All of Cassandra crammed into a 30 minute talk with 5 slides of self-advertisement; impossible.

Talk was too fast but it gave an idea on how you can use cassandra on a specific project, useful.

Talk too short, i was hoping more details about scaling..

I don't agree with people saying: "product X takes care of that, so I don't need to know how it works", sooner or later you get in trouble and then you need to understand why.

Talk was too short and to fast.

The talk couldn't really get my attention. The goal and use cases of Cassandra weren't clear to me. Apparently it scales well, but what are the problems to tackle? How do you handle the implementation? How does it function compared to other systems?

For me, the implementation of specific problems is no goal for a presentation. It went very into detail how certain columns are named and how they are linked to each other, but it does not make a lot of sense if you don't have the context of the problem.

Some remarks
1. Please don't rush through your presentation. A quit pace makes listening more comfortable
2. Please explain the use cases. What is the problem? What is the goal? And how does your solution fit into?
3. Please don't commercialize your talk at the end. Focussing too much on your hiring doesn't make the audience feel comfortable about. If you mention it just once, there is no problem at all.

Hopefully you have the opportunity to give the talk another time, so you could try to improve some aspects.

A small phpcassa demo would be a great addition to this talk.
Try to limit the amount of text on your sheets and don't read them.

At the end it was not clear to me why I should migrate to cassandra. Especially with the pour PHP support far the latest version/options.

Maby presenting Cassandra in combination with PHP is just a few weeks to early.

The subject was presented too fast so that the theoretical part of the presentation wasn't always clear for a newbie who is not familiar with Cassandra. The real use cases were presented very shortly and not deeply enough. And reading text from a slide which contains a definition copied from the internet is just unacceptable at such kind of event.

With the title "Scalable PHP web applications with Apache Cassandra" I expected to learn some more basics, like simple queries etc. I like the topic, but it was a little deep for me as a beginner.
