Cassandra 3.0 - JSON at scale - StampedeCon 2015StampedeCon
This session will explore the new features in Cassandra 3.0, starting with JSON support. Cassandra now allows storing JSON directly to Cassandra rows and vice versa, making it trivial to deploy Cassandra as a component in modern service-oriented architectures.
Cassandra 3.0 also delivers other enhancements to developer productivity: user defined functions let developers deploy custom application logic server side with any language conforming to the Java scripting API, including Javascript. Global indexes allow scaling indexed queries linearly with the size of the cluster, a first for open-source NoSQL databases.
Finally, we will cover the performance improvements in Cassandra 3.0 as well.
Whether running load tests or migrating historic data, loading data directly into Cassandra can be very useful to bypass the system’s write path.
In this webinar, we will look at how data is stored on disk in sstables, how to generate these structures directly, and how to load this data rapidly into your cluster using sstableloader. We'll also review different use cases for when you should and shouldn't use this method.
Cassandra Community Webinar | Become a Super ModelerDataStax
Sure you can do some time series modeling. Maybe some user profiles. What's going to make you a super modeler? Let's take a look at some great techniques taken from real world applications where we exploit the Cassandra big table model to it's fullest advantage. We'll cover some of the new features in CQL 3 as well as some tried and true methods. In particular, we will look at fast indexing techniques to get data faster at scale. You'll be jet setting through your data like a true super modeler in no time.
Speaker: Patrick McFadin, Principal Solutions Architect at DataStax
This presentation introduces people to Cassandra and Column Family Datastores in general. I will discuss what Cassandra is, how and when it is useful, and how it integrates with Rails. I will also go in to lessons learned during our 3-month project, and the useful patterns that emerged. The discussion will be very technical, but targeted at developers who are not familiar with, or have not done a project with Cassandra.

Cassandra Day Chicago 2015: Advanced Data ModelingDataStax Academy
Speaker(s): Tim Berglund, Global Director of Training at DataStax
You know you need Cassandra for its uptime and scaling, but what about that data model? Let's bridge that gap and get you building your game changing app. We'll break down topics like storing objects and indexing for fast retrieval. You will see by understanding a few things about Cassandra internals, you can put your data model in the spotlight. The goal of this talk is to get you comfortable working with data in Cassandra throughout the application lifecycle. What are you waiting for?
DataStax Enterprise clients, such as CQLSH or Hadoop and Spark based applications, can be precisely configured to achieve a desired behaviour. For a basic use case, we just run a dedicated DSE command and do not care about how all of those pieces are setup to work together, leveraging the goodness of DSE. However, understanding where and what we need to modify to achieve the expected change in the configuration is essential for using DSE efficiently. In this presentation we go through the basic and advanced settings for client applications, including security features and limitations or DSE patches introduced into integrated Spark. We show the new tools which significantly simplify the configuration of external DSE installations which are used just for accessing DSE cluster in client mode. Finally, we conclude with hints for configuring Spark driver from scratch in order to use it in a web application, when running the program through DSE scripts is not feasible.

Simon Elliston Ball – When to NoSQL and When to Know SQL
With NoSQL, NewSQL and plain old SQL, there are so many tools around it’s not always clear which is the right one for the job.This is a look at a series of NoSQL technologies, comparing them against traditional SQL technology. I’ll compare real use cases and show how they are solved with both NoSQL options, and traditional SQL servers, and then see who wins. We’ll look at some code and architecture examples that fit a variety of NoSQL techniques, and some where SQL is a better answer. We’ll see some big data problems, little data problems, and a bunch of new and old database technologies to find whatever it takes to solve the problem.By the end you’ll hopefully know more NoSQL, and maybe even have a few new tricks with SQL, and what’s more how to choose the right tool for the job.

One of the major trends in data warehousing/data engineering is the transition from click-based ETL tools to using code for defining data pipelines. Nowadays, the vast majority of projects either start with a set of simple shell/ bash scripts or with platforms such as Luigi or Apache Airflow, with the latter clearly becoming the dominant player. In the past 6 years, Project A also followed this approach when building data warehouses for more than 20 of its portfolio companies and we are now open sourcing the underlying infrastructure (https://github.com/mara). Basically, it is a lightweight, opinionated Airflow, with a focus on transparency and complexity reduction. In this talk, I will guide you through some of the design decisions behind the platform and some general learnings for setting up successful data engineering teams.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

7. SLA Dashboard
• Create DA’s or
Groups in SCOM
• Define your Services
SLA and SLO
• Create Rollup and
Present
8. Demo
• Create a Group
• Put SLA on it
• Present it in varios ways
10. Bottleneck
• Is it slow?
• Identify the individual layers
• What’s Normal???
