Subject [jira] Commented: (JCR-1825) DBDataStore doesn't support concurrent reads
Date Tue, 21 Oct 2008 13:23:44 GMT

    [ https://issues.apache.org/jira/browse/JCR-1825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641374#action_12641374

Claus Köll commented on JCR-1825:
---------------------------------

i would also prefer to use the closeSilently Method from the DatabaseHelper instead of ConnectionRecoveryManager
so we can delete the Method in the ConnectionRecoveryManager

> 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.
