Ramesh Reddy updated TEIID-444:
-------------------------------
Fix Version/s: 6.1.0
Affects Version/s: 6.0.0
To support providing the Cache services at connector level, Teiid will provide following
two methods on the "ExecutionContext" interface in the Connector API
-- Object getFromCache(CacheScope scope, Object key);
-- void storeInCache(CacheScope scope, Object key, Object value);
Where CacheScope is defined as
public enum CacheScope {
REQUEST, // retained until end of every top level request
SESSION, // retained until end of user session termination
VDB, // retained for life of VDB
SERVICE, // retained for life of the service
GLOBAL; // common across system, query engine life cycle
}
except for REQUEST, the items placed in all other scopes will be replicated across the
cluster in server mode. In embedded, no replication is available.
Expose the cache to connectors.

Key: TEIID-444
URL: https://jira.jboss.org/jira/browse/TEIID-444
Project: Teiid
Issue Type: Feature Request
Components: Connector API
Affects Versions: 6.0.0
Reporter: John Doyle
Assignee: Ramesh Reddy
Fix For: 6.1.0
The XML-Relational connectors have historically had their own cache. I'm modifying
the connectors to use JBoss cache and it would benefit users if this connector and other
connectors with need of a cache could use the teiid cache to ease cache configuration and
monitoring.
