Subject [jira] Created: (JCR-1825) DBDataStore doesn't support concurrent reads

DBDataStore doesn't support concurrent reads

                 Key: JCR-1825
                 URL: https://issues.apache.org/jira/browse/JCR-1825
             Project: Jackrabbit
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: 1.5.0
            Reporter: Przemo Pakulski
             Fix For: 1.5.0

My understanding is that setting parameter copyWhenReading to true should allow concurrent
reads by spooling binary property to temporary file and free database resources (connection)
immediately to make it available for other threads.

After applying patch for JCR-1388, DBDataStore doesn't support concurrent reads anymore, resultSet
is kept open and db connection is blocked until the stream is read and closed. When copyWhenReading
is set to true db connection should be released immediately, this is the reason i guess why
temporary file is used.
