Spark Streaming has supported Kafka since it's inception, but a lot has changed since those times, both in Spark and Kafka sides, to make this integration more fault-tolerant and reliable.Apache Kafka 0.10 (actually since 0.9) introduced the new Consumer API, built on top of a new group coordination protocol provided by Kafka itself.
So a new Spark Streaming integration comes to the playground, with a similar design to the 0.8 Direct DStream approach. However, there are notable differences in usage, and many exciting new features. In this talk, we will cover what are the main differences between this new integration and the previous one (for Kafka 0.8), and why Direct DStreams have replaced Receivers for good. We will also see how to achieve different semantics (at least one, at most one, exactly once) with code examples.
Finally, we will briefly introduce the usage of this integration in Billy Mobile to ingest and process the continuous stream of events from our AdNetwork.

A Tale of Two APIs: Using Spark Streaming In ProductionLightbend
Fast Data architectures are the answer to the increasing need for the enterprise to process and analyze continuous streams of data to accelerate decision making and become reactive to the particular characteristics of their market.
Apache Spark is a popular framework for data analytics. Its capabilities include SQL-based analytics, dataflow processing, graph analytics and a rich library of built-in machine learning algorithms. These libraries can be combined to address a wide range of requirements for large-scale data analytics.
To address Fast Data flows, Spark offers two API's: The mature Spark Streaming and its younger sibling, Structured Streaming. In this talk, we are going to introduce both APIs. Using practical examples, you will get a taste of each one and obtain guidance on how to choose the right one for your application.

Developing Real-Time Data Pipelines with Apache KafkaJoe Stein
Developing Real-Time Data Pipelines with Apache Kafka http://kafka.apache.org/ is an introduction for developers about why and how to use Apache Kafka. Apache Kafka is a publish-subscribe messaging system rethought of as a distributed commit log. Kafka is designed to allow a single cluster to serve as the central data backbone. A single Kafka broker can handle hundreds of megabytes of reads and writes per second from thousands of clients. It can be elastically and transparently expanded without downtime. Data streams are partitioned and spread over a cluster of machines to allow data streams larger than the capability of any single machine and to allow clusters of coordinated consumers. Messages are persisted on disk and replicated within the cluster to prevent data loss. Each broker can handle terabytes of messages. For the Spring user, Spring Integration Kafka and Spring XD provide integration with Apache Kafka.

Apache Spark has emerged over the past year as the imminent successor to Hadoop MapReduce. Spark can process data in memory at very high speed, while still be able to spill to disk if required. Spark’s powerful, yet flexible API allows users to write complex applications very easily without worrying about the internal workings and how the data gets processed on the cluster.
Spark comes with an extremely powerful Streaming API to process data as it is ingested. Spark Streaming integrates with popular data ingest systems like Apache Flume, Apache Kafka, Amazon Kinesis etc. allowing users to process data as it comes in.

Hari will finally discuss how to write a custom application and a custom receiver to receive data from other systems.
Some of the biggest issues at the center of analyzing large amounts of data are query flexibility, latency, and fault tolerance. Modern technologies that build upon the success of “big data” platforms, such as Apache Hadoop, have made it possible to spread the load of data analysis to commodity machines, but these analyses can still take hours to run and do not respond well to rapidly-changing data sets.
A new generation of data processing platforms -- which we call “stream architectures” -- have converted data sources into streams of data that can be processed and analyzed in real-time. This has led to the development of various distributed real-time computation frameworks (e.g. Apache Storm) and multi-consumer data integration technologies (e.g. Apache Kafka). Together, they offer a way to do predictable computation on real-time data streams.
In this talk, we will give an overview of these technologies and how they fit into the Python ecosystem. As part of this presentation, we also released streamparse, a new Python that makes it easy to debug and run large Storm clusters.

Chicago Data Summit: Flume: An IntroductionCloudera, Inc.
Flume is an open-source, distributed, streaming log collection system designed for ingesting large quantities of data into large-scale data storage and analytics platforms such as Apache Hadoop. It has four goals in mind: Reliability, Scalability, Extensibility, and Manageability. Its horizontal scalable architecture offers fault-tolerant end-to-end delivery guarantees, support for low-latency event processing, provides a centralized management interface , and exposes metrics for ingest monitoring and reporting. It natively supports writing data to Hadoop's HDFS but also has a simple extension interface that allows it to write to other scalable data systems such as low-latency datastores or incremental search indexers.
Deploying Apache Flume to enable low-latency analyticsDataWorks Summit
The driving question behind redesigns of countless data collection architectures has often been, ?how can we make the data available to our analytical systems faster?? Increasingly, the go-to solution for this data collection problem is Apache Flume. In this talk, architectures and techniques for designing a low-latency Flume-based data collection and delivery system to enable Hadoop-based analytics are explored. Techniques for getting the data into Flume, getting the data onto HDFS and HBase, and making the data available as quickly as possible are discussed. Best practices for scaling up collection, addressing de-duplication, and utilizing a combination streaming/batch model are described in the context of Flume and Hadoop ecosystem components.

Spark (Structured) Streaming vs. Kafka Streams - two stream processing platfo...Guido Schmutz
Independent of the source of data, the integration and analysis of event streams gets more important in the world of sensors, social media streams and Internet of Things. Events have to be accepted quickly and reliably, they have to be distributed and analyzed, often with many consumers or systems interested in all or part of the events. In this session we compare two popular Streaming Analytics solutions: Spark Streaming and Kafka Streams.
Spark is fast and general engine for large-scale data processing and has been designed to provide a more efficient alternative to Hadoop MapReduce. Spark Streaming brings Spark's language-integrated API to stream processing, letting you write streaming applications the same way you write batch jobs. It supports both Java and Scala.
Kafka Streams is the stream processing solution which is part of Kafka. It is provided as a Java library and by that can be easily integrated with any Java application.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.
