  • CASSANDRA - Choosing the right cloud instances for success

    York Butter Factory

    Knowing how to maximise your investment on the cloud can be sometimes difficult even for the experienced. In this month's Meetup, we will discuss how to select the correct cloud instances and why: - false economy, instances costing you more - IOPS and what is required for C* workloads - understanding your app - read vs write heavy - are ephemeral disks evil? - a time to kill instances - they're not your pets This month's Meetup will be co-hosted with the AWS Group so there will be other AWS topics covered. We hope to see many Cassandra rebels there!

  • Introduction to Cassandra 3.x and beyond + Graph & Spark

    York Butter Factory

    The 3.x versions of Apache Cassandra brought a lot of changes to the way data is stored and manipulated. It's exciting, even for people who have been using it since version 0.4. For this session we will give four 20 minute talks: 1) Introduction to Cassandra Explaining some of the architecture and operations that Cassandra uses to operate of as cluster of machines, how it handles consistency, and the basics of reading and writing data to disk. 2) What's new in CQL Looking at recent improvements such as Materialised Views, UDF and UDAs (well, they were 2.2 but who's counting), per partition Limits, and why you dont have to "freeze" your UDT's. 3) Storage Engine Changes Diving into the new 3.X storage engine format, a major re-write of the on disk format. The storage engine now understands the CQL layout and optimises the bytes used on disk and how they are accessed. 4) The Bleeding Edge Talking about what has just arrived and what is coming. This talk will touch on ideas like SASI indexes, Change Data Capture, Partition Level Aggregations. and Thread Per Core. CLOSING A quick overview of new features in the upcoming major release of DataStax Enterprise including DSE Graph and new Spark integrations.

  • HANDS ON - Build a Spark cluster on Cassandra

    York Butter Factory

    As the title states, the session is completely hands-on where you get to build your very own Spark cluster on Cassandra. Yes, you heard it right --- you will be building the cluster yourself. Swags! Santa Claus is coming early this year! It doesn't matter if you've been naughty. If you attend this month's meetup, I will guarantee that you get a Cassandra shirt. Please let me know your preferred size. Here is a rough size guide measured around the chest: • Small - 85 cm • Medium - 95 cm • Large - 105 cm • X Large - 115 cm And for those who have been nice, there will be extra surprise presents in the bag for you! Pre-requisites • Bring your own laptop • Your own Linux virtual machine • Your free DataStax account from https://academy.datastax.com/ (https://academy.datastax.com/Please) • Please RSVP! Your own laptop This is a hands-on session where you will get free training on setting up your own cluster in real-time. If you don't have a laptop, then you will not be able to follow the session at all. Linux VM There are several choices for you here. You can either: • run and install a Linux VM on your machine, or • use a VM on the cloud If you choose to run a VM on your machine, you can use VMware or VirtualBox (free). It doesn't matter whether you install Ubuntu, CentOS or RedHat. If you prefer the cloud, you can take advantage of the following FREE offerings: • https://aws.amazon.com/free/ • https://cloud.google.com/free-trial/ • https://azure.microsoft.com/en-us/pricing/free-trial/ You will need a minimum of 1 Linux VM but to get the most out of the session, I would recommend at least 3 Linux VMs. DataStax Account This is a FREE account which allows you to download the full suite of DataStax software to use which ever way you choose. It also allows you to access the FREE courses provided by DataStax. Signing up for an account on https://academy.datastax.com/ is pretty quick and simple. You don't need a company email --- the email addresses are just used by a robot which automatically emails the credentials back to you. Please RSVP I would appreciate it if you could RSVP on http://www.meetup.com/Melbourne-Cassandra-Users/events/226071326/ for catering purposes. I am also aiming to steer away from the usual pizzas and instead organise healthier options including vegetarian so thanks for your cooperation! Venue The meetup will be held in the usual location --- York Butter Factory, 62 King St (between Collins St & Flinders La). Entry is usually via the glass doors but if you arrive after 6pm, access is via the red double doors on the left of the glass doors (ring bell if necessary). Issues? Questions? If you have any issues or have any questions about the meetup, please contact me immediately. I don't want anyone to miss out and if you have issues with VMs, etc., let me know as I will see if I can make arrangements. See you at the meetup! Erick Ramirez, Cassandra Meetup Organiser
