Liquid Stream Processing Across Web Browsers and Web ServersMasiar Babazadeh
ICWE2015 presentation on the control infrastructure of the Web Liquid Streams framework, a data stream framework developed at the University of Lugano, Switzerland.
early benchmarks on pre-release Gnocchi v4. includes benchmark comparison between all-ceph v3.x driver versus all-ceph v4 driver. also, shows benchmark using redis+ceph deployment.
A key feature when monitoring and debugging any Cloud infrastructure is to provide the ability to trace, track, and collate all the individual, discrete steps that compose an event. A typical resource action in OpenStack is often a combination of smaller tasks -- which given the distributed nature of OpenStack -- can fail at unpredictable points in the workflow. By collecting the appropriate events, operators can view all events within Ceilometer, filter on a failed action and trace back the history of related events to spot anomalies or errors. In this talk, we provide an overview of the recent enhancements made in Ceilometer to support the collection of event notifications from OpenStack services. We will describe: how events are processed, transformed and stored in Ceilometer; how you can derive metrics from events; and how it’s possible to track the events of a resource and analyse where errors occur.

Streams are Node’s best and most misunderstood idea. In this talk, I try to explain the concept of streams as simple as possible. We also do live coding and solve some real time problems using streams.
THE RED METHOD: HOW TO INSTRUMENT YOUR SERVICESInfluxData
In this talk, Tom Wilkie will discuss patterns of application instrumentation, where and when they are applicable, and how they can be implemented with Prometheus. He’ll cover Google’s Four Golden Signals, the RED Method, the USE Method, and Dye Testing. He’ll also discuss why consistency is an important approach for reducing cognitive load. Finally, he’ll talk about the limitations of these approaches and what can be done to overcome them.

Cassandra is awesome for many things. One of the things it's awesome for is Time Series. Combining the power of Cassandra with APIs of existing Time Series tools, such as Graphite can yield interesting results.
Cyanite is a Time Series aggregator and store built on top of Cassandra. It's fully compatible with Graphite, can serve as a plug-in replacement for Graphite and Graphite web.
Cyanite is using SASI indexes to make glob metric path queries, can query and aggregate, store, display and analyse metrics from hundreds and thousands of servers.
Which data modelling practices work best for Time Series, which new awesome Cassandra features you can use to make your Time Series analysis better.

Introduction to GraphQL (or How I Learned to Stop Worrying about REST APIs)Hafiz Ismail
Talk for FOSSASIA 2016 (http://2016.fossasia.org)
----
This talk will give a brief and enlightening look into how GraphQL can help you address common weaknesses that you, as a web / mobile developer, would normally face with using / building typical REST API systems.
Let's stop fighting about whether we should implement the strictest interpretation of REST or how pragmatic REST-ful design is the only way to go, or debate about what REST is or what it should be.
A couple of demos (In Golang! Yay!) will be shown that are guaranteed to open up your eyes and see that the dawn of liberation for product developers is finally here.
Background: GraphQL is a data query language and runtime designed and used at Facebook to request and deliver data to mobile and web apps since 2012.
Hafiz Ismail (@sogko) is a contributor to Go / Golang implementation of GraphQL server library (https://github.com/graphql-go/graphql) and is looking to encourage fellow developers to join in the collaborative effort.

GraphQL: The Missing Link Between Frontend and Backend DevsSashko Stubailo
Engineers working on backend data services are often focused on operational concerns like data consistency, reliability, uptime, and storage efficiency. Because each situation calls for a specific set of tradeoffs, one organization can end up with a diverse set of backend databases and services. For the people building the UI and frontend API layers, this diversity can quickly become an issue, especially if the same client needs to call into multiple backends or fetch related objects across different data sources.
GraphQL is a language-agnostic API gateway technology designed precisely to solve this mismatch between backend and frontend requirements. It provides a highly structured, yet flexible API layer that lets the client specify all of its data requirements in one GraphQL query, without needing to know about the backend services being accessed. Better yet, because of the structured, strongly typed nature of both GraphQL queries and APIs, it's possible to quickly get critical information, such as which objects and fields are accessed by which frontends, which clients will be affected by specific changes to the backend, and more.
In this talk, I'll explain what GraphQL is, what data management problems it can solve in an organization, and how you can try it today.
GraphQL is a new API technology that makes it easy to describe the data available in your backend, and then fetch it with a simple query language. In this talk, I go over some of the reasons this is especially great for frontend developers.
GraphQL is an application layer query language from Facebook. With GraphQL, you can define your backend as a well-defined graph-based schema. Then client applications can query your dataset as they are needed. GraphQL’s power comes from a simple idea — instead of defining the structure of responses on the server, the flexibility is given to the client. Will GraphQL do to REST what REST did to SOAP?

as a quality assurance engineer. In 1993, he moved to the DACS (Data
Acquisition and Control System) team where he helped design and build
site-wide data collection system in VisualWorks and GemStone/S
Smallalk.

There are 600+ arguments that you can pass to JVM just around Garbage collection and memory. It’s way too many arguments for anyone to digest and comprehend. In this session, 7 important JVM arguments that will boost your application performance will be highlighted.
Presented by Gregg Donovan, Senior Software Engineer, Etsy.com, Inc.
Understanding the impact of garbage collection, both at a single node and a cluster level, is key to developing high-performance, high-availability Solr and Lucene applications. After a brief overview of garbage collection theory, we will review the design and use of the various collectors in the JVM.
At a single-node level, we will explore GC monitoring -- how to understand GC logs, how to monitor what % of your Solr request time is spend on GC, how to use VisualGC, YourKit, and other tools, and what to log and monitor. We will review GC tuning and how to measure success.
At a cluster-level, we will review how to design for partial availability -- how to avoid sending requests to a GCing node and how to be resilient to mid-request GC pauses.For application development, we will review common memory leak scenarios in custom Solr and Lucene application code and how to detect them.
