[teiid-issues] [JBoss JIRA] (TEIID-2704) DB2 lob values must be read inline

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2704?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12825917#comment-12825917 ] 

Steven Hawkins commented on TEIID-2704:
---------------------------------------

Addressed in master/8.6 by moving the type handling logic from datatiertuple source into the ConnectorWorkItem - this allows copyLobs to work on a row by row basis.  So in 8.6 with copyLobs enabled, DB2 will work as expected with respect to lobs.

This change though is broader than I would like and doesn't seem well suited for backport.  At least for 7.7.9 the fix will just be to read all db2 lob values in a non-memory safe way as strings and byte arrays.
