LOB handling strategry issues
-----------------------------

                 Key: TEIID-1252
                 URL: https://jira.jboss.org/browse/TEIID-1252
             Project: Teiid
          Issue Type: Quality Risk
          Components: Query Engine
    Affects Versions: 7.1
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 7.1.1


LOBs returned from sources cause executions to stay alive until the user query has been completed - this is true even if the LOB values are not returned to the user.
Whenever an execution is kept alive, it's associated connection is held until the execution is closed - thus source connections may be held out of their pool indefinately.
Currently each source execution will attempt to obtain a new connection from the pool, which with LOB handling will cause potentially many connections even to the same source to be held out of the their pool indefinitely.
