The Essence of Caching - Ehcache

Google Tech Talk
January 24, 2011

Presented by Greg Luck, Founder of Ehcache, Ehcache CTO of Terracotta.

ABSTRACT

In this talk we will start with a performance problem and lead you through solving it with caching, discovering along the way the problems of distributed caching and their solutions. This will equip you with the tools to analyze a performance situation and to see whether a cache will help and what type of cache to apply. Then we'll talk about Ehcache: New and Notable that walks us from standalone Ehcache which Java developers at Google are probably familiar with to the Distributed Ehcache with Terracotta and then to new features like Search, Write-Behind and Transactions.

Topics include:

- The nature of system load
- Desirable Properties of Scalable Systems
- Caching as a solution for off-load, scale out and performance
- Why caching works
- Tiered Cache Design
- SOR Coherency Problem and Solutions
- N * Problem and Solution
- Cache Cluster topologies
- Cache Coherency Problem and Solutions
- CAP and PACELC constraints

@Arvoitusmies Probably a typo (happens to me every year throughout January...): In the presentation, he references Terracotta BigMemory which was only released in November 2010.

This may be outdated but it's been useful to me.

It is interesting to know that you don't need to have a cluster of application servers and replicated databases, you just need to cache properly :)
