public class ConfigDataCache
extends AbstractMTAsynchronouslyRefreshedCache<ConfigDataCache.ConfigData>

An innder class that uses the config service to asynchronously refresh tenant config data.

Cluster-wide invalidation messages mean that we have to be very careful about only making updates to caches when entries really change. However, the nature of the ConfigService hierarchy makes it very difficult to do this in a deterministic manner without performing write locks that run across tenants. By receiving asynchronous messages to refresh we no longer have to rely on a cluster-aware cache.

Since:

4.1.5

Method Detail

setRepoXMLConfigService

public void setRepoXMLConfigService(RepoXMLConfigService repoXMLConfigService)

Set the config service. Depending on the order of injection, this might have to be done by code.

buildCache

protected ConfigDataCache.ConfigData buildCache(java.lang.String tenantId)

Description copied from class: AbstractMTAsynchronouslyRefreshedCache

Build the cache entry for the specific tenant. This method is called in a thread-safe manner i.e. it is only ever called by a single thread.
