This document describes how to use a Groovy scripting component to pause a Mule flow for a period of time by calling the sleep method. The example flow picks up a file from an inbound location, passes it through a Groovy script that sleeps for 3 seconds, and then places the file in an outbound location. The Groovy component allows pausing the flow programmatically without using additional middleware.

Process file one after another
This document discusses how to process multiple files sequentially through a file endpoint in Mule. It explains that by default, all files will be processed together in parallel using multiple threads. However, by setting the processingStrategy of the flow to "synchronous", files can be picked up and processed one by one from the inbound folder and dispatched sequentially to the outbound folder. The document provides an example Mule configuration and demonstrates that when multiple files exist in the inbound folder, they will be deposited one by one into the outbound folder over time rather than all at once.
Groovy with Mule
This document demonstrates how to use a Groovy scripting component to pause a Mule flow for a period of time before processing the payload. The flow uses a file inbound endpoint to pick up a file, passes it to a Groovy script that sleeps for 3000ms, and then sends the file to a file outbound endpoint. The Groovy script allows pausing the flow by calling the sleep method, holding the payload for a specified interval before continuing processing.
Simple groovy example in mule
This document shows how to use a Groovy scripting component to hold a Mule flow for a period of time before processing the payload. The Groovy component uses the sleep method to pause the flow for 3000 milliseconds. This holds the file payload before writing it to the outbound location. The example flow uses a file inbound endpoint to pick up a file, passes it to the Groovy component which sleeps for 3 seconds, and then writes the file to the outbound location. This allows dynamically pausing a flow to hold the payload for a specified interval of time.

The flow uses a file inbound endpoint to pick up a file, passes it to a Groovy component that uses the sleep method to pause processing for 3000 ms, then writes the payload to an outbound file endpoint.
This allows inserting a delay between when a file is picked up and when it is written out, demonstrating how Groovy can be used to control flow timing in Mule applications.
Compressing & decompressing in mule
The document discusses using gzip compression and decompression transformers in Mule. It shows how to compress a file payload with gzip-compress-transformer, which reduces the file size from 83 KB to 21.99 KB as seen in the logs. It then demonstrates decompressing the compressed file back to its original size of 83 KB using gzip-uncompress-transformer. The flows pick up files from source folders, process them with the transformers, and write the results to destination folders, compressing and decompressing a sample "abc.doc" file as an example.
Groovy in Mule
This document discusses using a Groovy scripting component in Mule to add a delay to a flow. The Groovy component uses the sleep method to pause message processing for a specified time period. This allows holding the payload for a set interval before writing the file to the outbound location. The example flow reads a file from one directory, uses a Groovy script to sleep for 3000ms, then writes the file to another directory.
Caching and invalidating with managed store
This document discusses using the NonPersistentManagedObjectStore in Mule for caching and invalidating caches with simple configurations. It shows how to configure caching in a flow using the cache scope, retrieve cached data even after deleting from the database, and invalidate the entire cache using another flow to clear it. Testing is done using SoapUI to call the web service and observe the cached response versus a fresh response after cache invalidation.

Handle File on mule
The document discusses two ways to stop a Mule flow after processing a file: 1) stopping the flow at the end using a Groovy component, or 2) stopping the connector at the end. It focuses on the first option, showing how a Groovy script can call muleContext.registry.lookupFlowConstruct('Flow name').stop() to end the flow after a file has been read. This prevents any additional files from being processed by the inbound endpoint.
WebSockets with Spring 4
This document discusses WebSockets and Spring WebSockets. It begins by introducing WebSockets as a protocol for real-time full duplex communication over a single TCP connection. It then covers the WebSocket handshake process and JavaScript WebSocket API. Next, it discusses Java WebSocket implementations and how Spring 4 supports WebSockets and the fallback SockJS protocol. Finally, it introduces STOMP as a simple messaging protocol that can be used over WebSockets, and how Spring supports asynchronous messaging using STOMP over WebSockets.
Ruby Proxies for Scale, Performance, and Monitoring - GoGaRuCo - igvita.com
A high-performance proxy server is less than a hundred lines of Ruby code and it is an indispensable tool for anyone who knows how to use it. In this session we will first walk through the basics of event-driven architectures and high-performance network programming in Ruby using the EventMachine framework.
Servers with Event Machine - David Troy - RailsConf 2011
EventMachine allows Ruby programs to handle many concurrent connections without blocking or threads. It uses an asynchronous model where callbacks are invoked in response to I/O events like incoming connections or data. EventMachine provides a high performance non-blocking TCP server that handles all I/O with callbacks rather than blocking. It can be used to build scalable I/O intensive applications like email servers that handle thousands of concurrent connections in a single Ruby process. The key is to never block the EventMachine reactor loop.
JavaScript development methodology
The document discusses several development methodologies including:
1. Using package managers like NPM and Bower to simplify installing dependencies and ensuring consistent versions.
2. Writing automated tests with libraries like Mocha to catch bugs and ensure code works as intended.
3. Conducting A/B testing and experiments to learn what customers value and determine the best product iterations from data.
Vagrant
Vagrant allows developers to easily create and manage virtual machine environments for development. It provides a simple configuration file format and CLI to automate the setup of VMs using various providers like VirtualBox, VMware, AWS, and more. Vagrant can provision VMs using tools like Chef, Puppet, Ansible and Shell scripts. It aims to allow exact clones of production environments for testing and to simplify tasks like testing infrastructure changes.
Messaging with the Docker
Docker is a platform for running and managing Linux containers that provides lightweight virtualization compared to traditional virtual machines. It allows applications to be packaged into standardized units called containers that have all their dependencies and can be run on any infrastructure that supports Docker. Docker improves deployment by allowing applications to be easily moved between development, testing, and production environments using self-contained images. As Docker grows in popularity, companies like Red Hat are integrating it into their middleware products and looking to distribute software via Docker containers and images.

This document contains information about a minimal browser operating system called xPUD. It is very small, weighing under 35MB, and boots within 10 seconds. It uses a web interface and framework called "plate" to provide functionality typically found on desktop systems like window management and WiFi setup through a web browser. The document provides links to the GitHub source code page and the project website for more details on xPUD.
Potemkin PaaS
1. The document summarizes the Potemkin PaaS project from June 2010 which aimed to experiment with building a scalable runtime fabric using Java and OSGi that could run applications on-premises, in the public cloud, or in a hybrid environment.
2. An initial virtual appliance was created that could assemble and run a demo application. This was expanded to allow nodes to discover each other over multicast and form a distributed fabric.
3. Automation was added through a "boot scripts as a service" approach where each new node would contact a context service to learn its role and how to connect to other nodes, allowing the entire fabric to be deployed with a single command.
S&T What I know about Node 110817
Node is a JavaScript runtime environment that allows JavaScript to run on the server. It uses Google's V8 JavaScript engine and allows developers to build fast and scalable network applications using JavaScript. Node installs with NPM (Node Package Manager), which is used to install dependencies and share JavaScript code as reusable modules. Many modern web development processes use Node and NPM together to compile assets, run tasks, and share code.
JavaScript is the new black - Why Node.js is going to rock your world - Web 2...
Node.js allows JavaScript to be used for server-side programming. It is a popular choice because JavaScript programmers can reuse code and libraries on both the client-side and server-side. Node.js is also fast and non-blocking which allows for high concurrency levels. The Node.js ecosystem includes many libraries like Express for building web servers and Mustache.js for templating that make building server-side JavaScript applications easy.
Node.js for Rubists
Node.js is an asynchronous I/O library for JavaScript that aims to provide an easy way to build scalable network programs. It keeps slow operations from blocking other operations through non-blocking I/O and by utilizing a single-threaded event loop model. This allows Node.js applications to handle a large number of concurrent connections using a single process, without the overhead of threads. CommonJS modules provide portability for JavaScript libraries between Node.js and other environments like browsers.
Modern frontend workflow
This document discusses modern frontend workflows using Yeoman, Grunt, and Bower. Yeoman provides generators to scaffold projects and boilerplate code. Grunt is a task runner that automates tasks like linting, testing, concatenating, and minifying files. Bower is a package manager for frontend dependencies. Together these tools automate repetitive setup tasks, allow running development servers, building projects, and managing dependencies from the command line.
Websockets and SockJS, Real time chatting
SockJS is a browser JavaScript library that provides a WebSocket-like object. It gives a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server.
Under the hood SockJS tries to use native WebSockets first.
SockJS is intended to work for all modern browsers and in environments which don't support the WebSocket protocol. In this slide a real time chat application using SockJS (sockjs-1.1.1.min.js as SockJS-client, SockJS-node as SockJS-server) step by step development is also shown.
Node js
Node.js is a JavaScript runtime built on Chrome's V8 engine that allows JavaScript to run on the server side or as a standalone application. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, as it can handle multiple concurrent connections while waiting for responses. Common uses of Node.js include building web servers, real-time applications, command line tools, and more due to its asynchronous and event-driven nature.
Ruby e xmpp
This document discusses using Ruby and XMPP for building messaging applications. It recommends using the Blather library to connect to XMPP and DaemonKit for managing Ruby processes as daemons. DaemonKit provides a Rails-like structure and tools for logging, starting, stopping processes and managing environments. An example shows registering a user on Ejabberd, a popular XMPP server, in a simple way using the ejabberdctl command.
SockJS Intro
SockJS provides a WebSocket-like API that works across all browsers, including older browsers, by using multiple transport mechanisms as needed such as xhr-polling. It supports both client-side and server-side libraries for major platforms. While SockJS mimics the WebSocket API, it is simpler than solutions like Socket.IO that provide additional functionality beyond a raw protocol.
Unity and WebSockets
This document discusses using WebSockets in Unity games and describes how to implement a finite state machine to handle asynchronous WebSocket events on the main thread. It begins with an overview of WebSockets and their advantages over polling. It then demonstrates how to connect to a WebSocket server and handle events like connection, receiving messages, and disconnection using the WebSocket Sharp library. To address Unity's single-threaded model, it presents a finite state machine pattern that queues asynchronous WebSocket events to be processed on the main thread. Sample code is provided to illustrate setting up and transitioning between states to safely coordinate the WebSocket connection and events.

It provides an example of a custom interceptor that caches payload data and reuses it when the same request is made. The document demonstrates testing the cache by making a request, deleting related data from the database, and confirming the same response is returned from the cache rather than refetching from the database. It concludes that a custom interceptor can provide caching capabilities in Community Edition similar to the cache scope in Enterprise Edition.
Cache for community edition
This document discusses implementing a cache in Mule Community Edition using a custom interceptor since Community Edition does not include the cache scope feature of Enterprise Edition. It provides an example of a custom interceptor class that caches payload data and includes a code sample. The document then demonstrates configuring and testing the custom cache interceptor on a web service that retrieves database records, showing that it continues returning the cached response even after the underlying database record is deleted.
Cache for community edition
This document discusses implementing a cache in Mule Community Edition using a custom interceptor, as the cache scope is only available in the Enterprise Edition. It provides an example of a custom interceptor that caches payload data and applies a filter expression. The flow is divided into two parts connected by a VM component. The interceptor is used and configured with a filter expression property. Testing is done using SoapUI to call the web service and validate that the cached response is returned even after deleting the cached data from the database.

- 1. Simple Groovy example in Mule BY MURALIDHAR.GUMMA
- 2. We often want to stop our flow for sometime and then want to process it after an interval of time. In Java we can use Sleep method to hold our thread for a specific period of time
- 3. But how can we use Sleep method in Mule?? .
- 4. Here I will show you how ……
- 5. Let us consider we have a following Mule flow :- Now you can see in the above flow the inbound endpoint will pic a file from a location and put it into another location. But what if we want to hold the flow for sometime before it put the file in the outbound location ??? How can we hold the file for an particular interval of time ???
- 6. Yes .. We can do it by using sleep method in our flow
- 7. So, we need Groovy component to implement sleep method:-
- 8. So our Mule flow will be now following :- This Groovy component will be holding the payload for some time
- 9. The corresponding Mule flow will be :- <file:connector name="File_Global" autoDelete="true" outputAppend="true" streaming="true" validateConnections="true" doc:name="File"/> <flow name="Flow1" doc:name="Flow1"> <file:inbound-endpoint path="E:backuptest" responseTimeout="10000" doc:name="File" connector- ref="File_Global"> <file:filename-regex-filter pattern="abc.txt" caseSensitive="false"/> </file:inbound-endpoint> <scripting:component doc:name="Groovy"> <scripting:script engine="Groovy"> <![CDATA[ sleep(3000); System.out.println("Holding the flow for 3000 ms"); return message.payload;]]> </scripting:script> </scripting:component> <file:outbound-endpoint path="E:backuptestnewfolder" responseTimeout="10000" doc:name="File"/> </flow>
- 10. So, if we start our application again and put the inbound file in the location E:backuptest , we will get the following in our console :-
- 11. And we will get the file in our outbound location E:backuptestnewfolder after 3000 ms
- 12. Hope you enjoyed the simple yet an amazing trick in Mule
