[teiid-issues] [JBoss JIRA] (TEIID-2153) Allow LOBs to be accessable after the statement close in the local connection scenarios
[
https://issues.jboss.org/browse/TEIID-2153?page=com.atlassian.jira.plugin...
]
Steven Hawkins resolved TEIID-2153.
-----------------------------------
Resolution: Done
Changed the code to allow cache entry lobs to be readable after close as the filestore
will not be removed until all of the lobs are gc'd.
Also I'll treat more proactive lob cleanup as a separate issue. We'll need to
distinguish between persistent values created by processing (as opposed to cache/source
values) and remove their stores only on the removal of the requestbuffer. removal based
upon intermediate buffers would result in invalid blobs unless we have better reference
tracking.
Allow LOBs to be accessable after the statement close in the local

Key: TEIID-2153
URL: https://issues.jboss.org/browse/TEIID-2153
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Affects Versions: 8.0
Reporter: Ramesh Reddy
Assignee: Steven Hawkins
Fix For: 8.2
When a LOB returned the resultset, the contents of it are only accessed when
resultset/statement and/or connection object is not closed, so that internal resources can
be appropriately cleaned up.
This can be relaxed in the local connection scenarios, as the data access is occurring in
the same VM, by taking advantage of single read nature of SQL/XML to cleanup once the
resource is read or closed.
