[infinispan-issues] [JBoss JIRA] (ISPN-8722) Impossible to create replicated/distributed cache configuration based on scattered cache configuration

[Paul Ferraro (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-8722?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro updated ISPN-8722:
-------------------------------
    Description: 
Consider an existing scattered cache configuration.

Configuration scatteredConfig = ...;
ConfigurationBuilder builder = new ConfigurationBuilder().read(scatteredConfig);
builder.clustering.cacheMode(CacheMode.DIST_SYNC);
Configuration distConfig = builder.build();

This throws:
{noformat}
org.infinispan.commons.CacheConfigurationException: ISPN000468: Invalidation batch size configuration options applies only to scattered caches.
        at org.infinispan.configuration.cache.ClusteringConfigurationBuilder.validate(ClusteringConfigurationBuilder.java:135)
        at org.infinispan.configuration.cache.ConfigurationBuilder.validate(ConfigurationBuilder.java:226)
        at org.infinispan.configuration.cache.ConfigurationBuilder.build(ConfigurationBuilder.java:283)
        at org.infinispan.configuration.cache.ConfigurationBuilder.build(ConfigurationBuilder.java:273)
{noformat}

The validation logic of ClusteringConfigurationBuilder specific requires the invalidationBatchSize attribute to be unset.  However, there is no way to "unset" an attribute.
https://github.com/infinispan/infinispan/blob/master/core/src/main/java/org/infinispan/configuration/cache/ClusteringConfigurationBuilder.java#L154

The same issue applies to the biasAcquisition and biasLifespan attributes in 9.2.x.
