[teiid-issues] [JBoss JIRA] (TEIID-2169) Buffer Manger's memory should be backed by Infinispan Cache

Ramesh Reddy created TEIID-2169: ----------------------------------- Summary: Buffer Manger's memory should be backed by Infinispan Cache Key: TEIID-2169 URL: https://issues.jboss.org/browse/TEIID-2169 Project: Teiid Issue Type: Feature Request Components: Query Engine, Server Reporter: Ramesh Reddy Assignee: Steven Hawkins Currently the buffer manager uses the memory from the local VM's heap for processing the intermediate query results, anything that overruns is saved on the disk. Using this model so far proven very efficient. However, when it comes to using the data grid as unlimited temp backing store where the results can be shared with other nodes in the case of fail-over of the session, this in current model does not work. By using the infinispan's local cache in standalone and replicated cache in distributed node for the buffer manager these issues can resolved. Issues may be, currently Buffer Manager uses efficient btree based index store, also the uses file storage in block. To make it work, Teiid needs to have access to the Infinispan's eviction queue and may also needs to implement the cache store. -- This message is automatically generated by JIRA.
