Class TempTableDataManager

java.lang.Object
  org.teiid.query.tempdata.TempTableDataManager

All Implemented Interfaces:

ProcessorDataManager

public class TempTableDataManager
extends java.lang.Object
implements ProcessorDataManager

This proxy ProcessorDataManager is used to handle temporary tables. This isn't handled as a connector because of the temporary metadata and the create/drop handling (which doesn't have push down support)

Constructor Summary

TempTableDataManager(ProcessorDataManager processorDataManager, BufferManager bufferManager, java.util.concurrent.Executor executor, org.teiid.dqp.internal.process.SessionAwareCache<org.teiid.dqp.internal.process.CachedResults> cache, org.teiid.dqp.internal.process.SessionAwareCache<org.teiid.dqp.internal.process.CachedResults> distibutedCache, CacheFactory cacheFactory)

Description copied from interface: ProcessorDataManager

Lookup a value from a cached code table. If the code table is not loaded, it will be loaded on the first query. Code tables should be cached based on a combination of the codeTableName, returnElementName, and keyElementName. If the table is not loaded, a request will be made and the method should throw a BlockedException.

Throws:

BlockedException
