Terracotta creator Ari Zilka talks about about the RAM is the new disk and argues for scaling up before scaling out, comparing the architectural approaches of lots of VMs with small heaps vs. a few JVMs with very large heaps. Ari introduces BigMemory, a Java add-on to Enterprise Ehcache, which allows app designs with huge amounts of memory accessible in-process, with minimal garbage collection.
Matthias Matook and Ari Zilka share the real-world experience of implementing Enterprise Ehcache at Australia's most visited online news sites. The talk will focus on the challenges and technical solutions to deal with massive page hits, high concurrency and how to achieve linear scalability without additional hardware.
Alex Miller explains shortly why caching is useful, followed by examples of typical difficulties encountered when setting up a cache, like large datasets, data eviction, stale data, replication, loading, duplication. Miller also discusses available choices for designing a distributed caching architecture, and ways to test a cache for performance.
Around January 2011, Memcached became the number one caching solution based on Java developer job demand. Memcached expanded beyond its LAMP roots. InfoQ caught up with Dustin Sallings, the implementer of Spymemcached the leading Java Memcached client, to get his perspective on the rise of Memcached in the Java world.
Distributed caching is the tip of the spear for performance, yet Java does not have a standard API. JSR-107 has gained some notoriety over the years because its old yet not done. Given the increased demand for caching, it seems JSR-107 will finally see the light of day, and be part of Java EE 7. InfoQ caught up with Greg Luck, JSR-107 specification and Ehcache lead developer to discuss.
Terracotta's BigMemory for Enterprise Ehcache product aims to by-pass Garbage Collection for objects held in the cache. InfoQ spoke to Amit Pandey, Chief Executive Officer at Terracotta, to find out more about the product.
The latest version of open source caching framework Ehcache supports terabyte cache and JAAS authentication with LDAP integration. Terracotta announced last week the general availability of Ehcache 2.2 version as part of Terracotta 3.3 release. The new version also includes a management console that provides visibility and control of run-time caching environment, for developers and operators.
The latest version of open source caching framework Ehcache supports write-behind caching and transaction management using Java Transaction API (JTA). It also includes a Hibernate 3.3 caching plugin, Bulk Loading API for clustered caches, and runtime cache reconfiguration.
Greg Luck provides an overview of alternate deployment configurations for a 1 terabyte cache based on EhCache Server.
