Writing Prefork Workers / Servers
The document discusses different approaches for writing job workers and servers in Perl, including using Parallel::Prefork for managing preforked processes, Server::Starter for hot-deploying servers, and Parallel::Scoreboard for monitoring prefork-based workers and servers. It provides code examples and compares the prefork and event-driven approaches.Read less

Kazuho@Cybozu Labs: Releasing Starlet 0.10, now runs faster than ever
Last Sunday my friend told me that Starman is now way faster than Starlet and I started to wonder why. There should not be such a difference between the two servers, sicne they share a lot in common. So I looked into the code yesterday, found the bottleneck and fixed them, as well as adding some tweaks. Here's what I did, and the chart[1] shows how the performance changed. 1) optimize the calcu

A Clever Way to Scale-out a Web Application
This document describes techniques for scaling out a web application across multiple database shards. It introduces Incline, which handles denormalization and data replication between shards transparently using triggers and queue tables. It also discusses Pacific utilities like mysqld_jumpstart for provisioning MySQL instances and pacific_divide for splitting shards without downtime. Incline addre

Incline - a trigger and queue based distributed materialized view manager Pacific - a set of perl scripts to manage MySQL shards, a MySQL shard can be split into two in less than 10 seconds of write blocking (and no read blocks) DBIx::ShardManager - a
Kazuho@Cybozu Labs: Writing Hot-deployable servers (introduction of Server::Starter)
Yesterday at YAPC::Asia 2009, I did a LT introducing verious techniques to write hot-deployable servers, and introduced a perl module called Server::Starter that encapsulates the burden of developing support for hot-deployment within each TCP server program. The presentation slides are on Slideshare.
