Terracotta OSS dev starter

The Terracotta Server Array (TSA) provides the platform for Terracotta products and the backbone for Terracotta clusters. It allows, for instance, to use Ehcache in a clustered mode, and benefit of a distributed in-memory cache. It is available as open source, and you may want to contribute to it, or even just build it yourself…

Terracotta toolkit

The Terracotta Toolkit is an API that provides you many functionalities in a clustered manner. E.g., you can get a Clustered ReadWrite Lock, so you can do synchronization between different applications running on different machines/JVMs. In 3.7, you get the Toolkit like this: ClusteringToolkit toolkit = new TerracottaClient("localhost:9510").getToolkit(); In 4.0, you get the Toolkit like…

Cet article résume les différents points que nous avons abordés (ou pas par manque de temps) lors du hands-on avec Mathilde Lemee (@MathildeLemee). 1) Le mot 'cache' est tiré du Québecquois, cache, qui dénomme originellement l'endroit ou on entrepose des réserves. Il vient du français 'cache' qui désignait l'endroit où on cachait ses réserves (comme…

Configure a nonstop cache programmatically in Ehcache

Here's how to configure programmatically a nonstop cache in Ehcache (this one is clustered, connecting to terracotta running on localhost): import net.sf.ehcache.config.*; Configuration configuration = new Configuration() .terracotta(new TerracottaClientConfiguration().url("localhost:9510")) .defaultCache(new CacheConfiguration("defaultCache", 10000)) .cache( new CacheConfiguration("nonstopCache", 10000) .terracotta(new TerracottaConfiguration().consistency(TerracottaConfiguration.Consistency.STRONG) .nonstop(new NonstopConfiguration().enabled(true).timeoutMillis(4000) .timeoutBehavior(new TimeoutBehaviorConfiguration() .type(TimeoutBehaviorConfiguration.TimeoutBehaviorType.LOCAL_READS.getTypeName()))) ) ); CacheManager cacheManager = new CacheManager(configuration);
