"Building a Distributed Task Scheduler With Akka, Kafka, and Cassandra" by David van Geest
 
36:39
Dynamically scheduled tasks are at the heart of PagerDuty's microservices. They deliver incident alerts, on-call notifications, and manage myriad administrative chores. Historically, these tasks were scheduled and run using an in-house library built on Cassandra, but that solution had begun to show its age. Early in 2016, the Core team at PagerDuty built a new Task Scheduler using Akka, Kafka, and Cassandra. After six weeks in development, the Scheduler is now running in production. This talk discusses how the strengths of the three technologies were leveraged to solve the challenges of resilient, distributed task scheduling. This talk will present a number of distributed system concepts in the real-world context of the Scheduler project. How can you dynamically adjust for increased task load with zero downtime? Can you guarantee task ordering across many servers? Do your tasks still run when an entire datacenter goes down? What happens if your tasks are scheduled twice? Attendees can expect to see how all of these challenges were addressed. Some familiarity with distributed queueing and actor systems will be helpful for attendees of this talk.

How to start with Spring Batch using Spring Boot – Java Config
 
07:46
http://javasampleapproach.com/spring-framework/spring-batch/start-spring-batch-using-spring-boot How to start with Spring Batch using Spring Boot – Java Config Many business operations need to process with batch job for critical environment. Spring Batch is a lightweight framework to boot the batch application. The tutorial will guide you how to start with Spring Batch using Spring Boot. Related Artical: How to start with Spring Batch using Spring Boot – XML Config I. Technologies for Spring Batch tutorial – Java 1.8 – Maven 3.3.9 – Spring Tool Suite – Version 3.8.1.RELEASE – Spring Boot: 1.4.0.RELEASE II. Overview 1. Structure of project 2. Step to do – Create Spring Boot project – Add needed dependencies – Configure datasource for Batch Job Repository – Create Step:Reader, Processor, Writer – Configure Batch Job – Create a Controller for launch Job – Run & Check result 3. Demo Video III. Practices 1. Create Spring Boot project 2. Add needed dependencies – Add dependencies: Web MVC, Spring Batch, PostgreSQL 3. Config datasource for Batch Job repository 4. Create Step:Reader, Processor, Writer public interface ItemReader: Strategy interface for providing the data. Implementations are expected to be stateful and will be called multiple times for each batch, with each call to read() returning a different value and finally returning null when all input data is exhausted. Implementations need not be thread-safe and clients of a ItemReader need to be aware that this is the case. A richer interface (e.g. with a look ahead or peek) is not feasible because we need to support transactions in an asynchronous batch. public interface ItemProcessor: Interface for item transformation. Given an item as input, this interface provides an extension point which allows for the application of business logic in an item oriented processing scenario. It should be noted that while it’s possible to return a different type than the one provided, it’s not strictly necessary. Furthermore, returning null indicates that the item should not be continued to be processed. public interface ItemWriter: Basic interface for generic output operations. Class implementing this interface will be responsible for serializing objects as necessary. Generally, it is responsibility of implementing class to decide which technology to use for mapping and how it should be configured. 5. Enable Spring Batch In main class, use @EnableBatchProcessing: Enable Spring Batch features and provide a base configuration for setting up batch jobs in an @Configuration class. 6. Configure Batch Job Create a configuration file and enable Spring batch via annotations: – @Configuration 7. Create a Controller for launch Job Create a simple controller JobLauncherController with 1 @RequestMapping(“/launchjob”) org.springframework.batch.core.launch.JobLauncher: Simple interface for controlling jobs, including possible ad-hoc executions, based on different runtime identifiers. It is extremely important to note that this interface makes absolutely no guarantees about whether or not calls to it are executed synchronously or asynchronously. The javadocs for specific implementations should be checked to ensure callers fully understand how the job will be run. org.springframework.batch.core.JobParameters: Value object representing runtime parameters to a batch job. Because the parameters have no individual meaning outside of the JobParameters they are contained within, it is a value object rather than an entity. It is also extremely important that a parameters object can be reliably compared to another for equality, in order to determine if one JobParameters object equals another. Furthermore, because these parameters will need to be persisted, it is vital that the types added are restricted. This class is immutable and therefore thread-safe. 8. Run & Check result – Maven build:clean install – Run project with mode: Spring Boot App Make a request:http://localhost:8080/launchjob IV. Source code SpringBatch

13.7 Multithreading Synchronized Keyword
 
10:17
In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. Multithreading in java is a process of executing multiple activities can proceed concurrently in the same program. Thread is basically a lightweight sub-process, a smallest unit of processing. In multithreading threads share a common memory area. They don't allocate separate memory area so saves memory, and context-switching between the threads takes less time than process. Multiple threads can exist within the same process and share resources such as memory, while different processes do not share these resources. Using two different task at the same time means multi-tasking. Thread is unit of a process.

In this session, we'll observe various instances of the majestic `Flux` and `Mono` in their natural habitat, the JVM. We'll look past the APIs and Reactive Stream concepts, towards less abstract matters such as the Reactor execution model (is there even such a thing?). What is the difference between assembly time and execution time? What is work stealing? Why does nothing happen until we subscribe? What is operator fusion? Magnets, how do they even work? Come join us and we'll try to answer all of these questions, and more!

Spring Batch Partition for Scaling & Parallel Processing
 
16:42
Link: http://javasampleapproach.com/spring-framework/spring-boot/spring-batch-partition-scaling-parallel-processing Spring Batch Partition for Scaling & Parallel Processing For Scaling & Parallel Processing, Spring Batch provides various solutions: Multi-threaded Step, Parallel Steps, Remote Chunking of Step & Partitioning a Step. In the tutorial, JavaSampleApproach will introduce Partitioning a Step cleary by a sample project. Related articles: – Spring Batch Job with Parallel Steps Link: http://javasampleapproach.com/spring-framework/spring-batch/spring-batch-job-parallel-steps – How to use Spring Batch Late Binding – Step Scope & Job Scope Link: http://javasampleapproach.com/spring-framework/spring-boot/use-spring-batch-late-binding-step-scope-job-scope Spring Batch provides an solution for partitioning a Step execution by remotely or easily configuration for local processing. The Job in left hand is executed sequentially, Master step is partitioning step that has some Slave steps. Slave steps can be remote services or local threads. For configuring partitioning step, Spring Batch provies PartitionHandler component & Partitioner interface. 1. PartitionHandler The componenet PartitionHandler knows about the kind of remote services(RMI remoting, EJB remoting,… or local threads) or grid numbers. PartitionHandler can send StepExecution requests to the remote Steps, in various format, like a DTO. The gridSize defines the number of step executions, so we should to consider the size of TaskExecutor’s thread pool. 2. Partitioner The Partitioner interface is used to build execution contexts as input parameters for step executions. Map contains a unique name for each step execution that associated with ExecutionContext’s value. 3. How to Binding input Map to Steps StepScope feature of Spring Batch can help us to late binding data from PartitionHandler to each step at runtime. See more: How to use Spring Batch Late Binding – Step Scope & Job Scope II. PRACTICE In the tutorial, we create a Batch Job that has only one partition step with 5 slave steps for inserting data from 5 csv files to MySql database.

Recorded at SpringOne Platform 2016. Speakers: Michael Minella,Glenn Renfro Slides: http://www.slideshare.net/SpringCentral/task-madness-modern-on-demand-processing The flexibility promised by cloud computing is something that hasn't been fully available in many use cases yet. Most application models are still based on long running containers, robbing users of that very flexibility. Spring Cloud Task, a new project in the Spring portfolio provides both functional and non-functional capabilities for building short lived, cloud-native, microservices. This talk will introduce the project as well as look at example applications. Since we're in Vegas, we're going to put that on demand processing to good use by demonstrating how we used it to generate a March Madness NCAA Men's Basketball Tournament bracket. We'll review how it worked, why Spring Cloud Task was the best fit for this type of application, and how we did this past March!

TPL Dataflow by Jon Gyllenswärd
 
22:25
Today programmers sit on huge computing resources but it's still hard to utilize that power to its full extent. Modern frameworks and tools like async/await and task parallel library makes it easier, but synchronization is still hard. What if there's another way, invented over 40 years ago? TPL Dataflow Library is a framework that sits on top of task parallel library. It uses asynchronous message passing, a technique that has been around since the early 70:s. The abstractions and declarative programming style it provides makes an excellent ground for creating more human-readable and testable code. But as always, there are pitfalls and lessons to be learned. Jon will first be giving a brief overview of the framework before diving into real life code and sharing experiences from a recent implementation of large scale risk calculations that use TPL Dataflow. There will be code! Jon Gyllenswärd is a Passionate developer, team lead and systems architect with over 17 years of experience in the IT industry. He has a heart for clean code, patterns, and architecture. When he's not at his daytime job as a consultant with factor10 he's always involved in a startup business or spare time coding project.

SpringBoot RetryTemplate Example  | Java Web Service Retry Design
 
12:35
Step by step guide how you can easily implement an automated Retry and Back-off policy within your Spring Java application. Enable your application to handle temporary failures when attempting to connect to a service or network resource. This can be done by enabling an automated retry policy that will perform the same operation that previously failed. The retry policy should have a maximum number of retries and either a dynamic back-off or incremental delay period. I recommend each service that you retry is idempotent. By designing for failure, you improve the stability of the application. If you enjoyed the video, please share, comment & subscribe for more great content!

User-level threads....... with threads. - Paul Turner - Google
 
34:00
"Multi-threaded programming is hard. Synchronous interfaces can help, but typically require lighter-weight representation of concurrency than a thread to implement efficiently. Frustratingly, this leads to a proliferation of both asynchronous and synchronous interfaces, depending on the language used. Over the past year we've been looking at how a uniform, performant, synchronous programming model can be implemented across all of Google's core languages (C++, Java, Go, Python), while maintaining compatibility with existing code. In this talk I will discuss new kernel interfaces which allow the use of regular threads in a co-operative fashion, with under 200ns context-switch times, and how new user-level primitives built on top of this support." http://www.linuxplumbersconf.org/2013/
The Web Platform Podcast 29: Reactive Extensions (Rx) in Practice
 
01:05:36
The Reactive Extensions (Rx) is a library for building async and event-based programs using observable sequences & query operators. Developers can use Rx to represent asynchronous data streams with Observables and query those data streams using LINQ operators. Rx can  utilize Schedulers to parameterize concurrency asynchronous data streams. Simply put, Rx = Observables + LINQ + Schedulers. Rx comes in many flavors and there are a lot of resources out there. Microsoft has open sourced this interesting and powerful way to work with async data streams so that we can all contribute and benefit from its strengths & weaknesses.Matthew Podwysocki (@mattpodwysocki), Microsoft ‘Open Sourcerer’, demystifies the Rx realm and opens our minds to new ideas. .
