This document provides an overview of a presentation on Laravel Octane given by Albert Chen. The presentation covered: the lifecycle of PHP and Laravel applications; an introduction to Laravel Octane and how it makes applications more friendly for long-lived processes; reminders for developing long-lived PHP applications; Laravel's service container and how containers work in Octane; how Octane supports concurrent tasks using Swoole; additional Octane features like tickers, caching, and process communication; blocking I/O in PHP and how coroutines work in Swoole; whether Octane supports coroutines; and a benchmark comparing Octane to PHP-FPM with Nginx. The document concludes with an
How to Build a High Performance Application with PHP and Swoole?Albert Chen
Albert Chen gave a presentation about using Swoole, an extension for PHP, to build high concurrency applications. Swoole provides asynchronous network capabilities that allow PHP applications to have an event-driven, non-blocking architecture. It addresses issues with PHP's blocking I/O and stateless model that limit scalability. Swoole improves performance by keeping the PHP code in memory and handling requests with coroutines instead of processes. While Swoole helps PHP applications achieve higher concurrency, traditional PHP code requires refactoring to fully utilize Swoole's features. Overall, Swoole extends PHP's capabilities for building high performance web applications.
This document summarizes a presentation about integrating the Laravel PHP framework with the Swoole extension. It discusses how Swoole provides high-performance asynchronous networking capabilities. Integrating Laravel with Swoole can boost performance by preloading the Laravel application and running requests in isolated "sandboxes" to prevent state from persisting between requests. This allows Laravel to take advantage of Swoole's asynchronous and non-blocking I/O without the typical overhead of Laravel's request lifecycle. Benchmarks show the integrated system can achieve a 5x performance increase over vanilla Laravel.
HAProxy is a free, open-source load balancer and reverse proxy that is fast, reliable and offers high availability. It can be used to load balance HTTP and TCP-based applications. Some key features include out-of-band health checks, hot reconfiguration, and multiple load balancing algorithms. Many large companies use HAProxy to load balance their websites and applications. It runs on Linux, BSD, and Solaris and can be used to load balance applications across servers on-premises or in the cloud.
From Generator to Fiber the Road to Coroutine in PHPAlbert Chen
The document discusses generators, fibers, and coroutines in PHP. It explains that generators allow for yielding values iteratively without building an array, while fibers provide each their own call stack allowing suspension at any point. Coroutines in Swoole make blocking I/O non-blocking through automatic yielding and resuming. Event loops power asynchronous non-blocking I/O by handling callbacks from I/O streams. Both generators and fibers are building blocks for implementing coroutines to improve PHP application concurrency.
This document discusses using caching to improve performance for web applications. It provides three key points:
1. Cache stores data to serve future requests faster by avoiding accessing the database. It is commonly used for things like login information, page content, and API responses.
2. There are different cache architectures like memcached and Redis that support storing data in-memory for fast retrieval. Factors like data size, update frequency, and consistency requirements determine the appropriate caching strategy.
3. Real-world examples show how companies like Facebook, Twitter, and Wonga use caching extensively to handle high volumes of traffic and database requests. Caching is critical to scaling applications in a cost-effective way.
Using The Mysql Binary Log As A Change StreamLuís Soares
The binary log records all data modifications made to tables logged by MySQL. It provides a sequential record of statements and changes that can be used for point-in-time recovery or to replicate data. The binary log files are persisted on disk and contain control events, transaction events, and row events representing changes. Applications can inspect the contents of the binary log through SQL statements or the mysqlbinlog tool to understand the recorded changes.
Open Swoole is a PHP extension that allows PHP applications to take advantage of asynchronous and coroutine programming models for building large scale concurrent systems. It was created in 2012 and provides features like TCP/UDP/HTTP servers, clients and protocols as well as coroutine support to improve performance over traditional PHP architectures.
Event-Driven Messaging and Actions using Apache Flink and Apache NiFiDataWorks Summit
At Comcast, our team has been architecting a customer experience platform which is able to react to near-real-time events and interactions and deliver appropriate and timely communications to customers. By combining the low latency capabilities of Apache Flink and the dataflow capabilities of Apache NiFi we are able to process events at high volume to trigger, enrich, filter, and act/communicate to enhance customer experiences. Apache Flink and Apache NiFi complement each other with their strengths in event streaming and correlation, state management, command-and-control, parallelism, development methodology, and interoperability with surrounding technologies. We will trace our journey from starting with Apache NiFi over three years ago and our more recent introduction of Apache Flink into our platform stack to handle more complex scenarios. In this presentation we will compare and contrast which business and technical use cases are best suited to which platform and explore different ways to integrate the two platforms into a single solution.
Nginx uses an event-driven architecture with a master process that manages worker processes. It handles requests non-blockingly and efficiently using techniques like memory pooling, buffer chaining, and an event-driven model. Key parts of the architecture include phases and handlers for HTTP requests, virtual servers, locations, and filters. Nginx also supports mail proxying and module development.
The document provides an overview of the libfabric interface for high performance networking. It discusses the high-level architecture including interfaces, services, and the object model. It describes the control interface for querying capabilities and attributes. It also presents a simple ping-pong example using reliable datagram messaging endpoints to illustrate basic usage.

- The document discusses the use of ref and reactive in Vue Composition API. Ref and reactive are methods used to define reactive data in Vue.
- Ref can be used on both objects and primitive values, while reactive only works on objects. When accessing a ref, the .value property must be used, while reactive data can be accessed directly.
- The document provides examples of ref and reactive implementation and compares their characteristics and proper usage. It also discusses a common development approach of extracting business logic into functions using ref and reactive.
This document discusses implementing lightweight concurrency in PHP. It introduces spatie/fork, an open source library for running PHP code concurrently. The library provides an easy to use solution for running code concurrently. It was created by Freek Van der Herten, who develops open source packages and has over 300 packages on Packagist with over 190 million downloads total.
This document discusses using the Stimulus JavaScript framework for frontend development. Stimulus is described as having modest ambitions and not seeking to take over the entire frontend like larger frameworks. It is designed to augment HTML with minimal behavior rather than handle rendering. Key aspects discussed include controllers, actions, targets, values, and the framework's lifecycle methods. The document suggests Stimulus lets developers easily write JavaScript and know where it should go.
This document discusses coding style, static code analysis, and PHP. It begins with an introduction to the speaker and outlines topics including what coding style is, PHP coding style standards like PSR-2 and PSR-12, and what static code analysis is. It then discusses specific static code analysis tools for PHP like PHPStan, Psalm, and Phan, covering how to install them, what kinds of checks they perform like syntax, type checks, and array shapes, and how to configure them.
