[ http://issues.apache.org/jira/browse/JCR-178?page=all ] Marcel Reutegger closed JCR-178: --------------------------------
> Allow concurrent index updates and queries > ------------------------------------------ > > Key: JCR-178 > URL: http://issues.apache.org/jira/browse/JCR-178 > Project: Jackrabbit > Type: Improvement > Components: query > Environment: svn revision: 231015 > Reporter: Marcel Reutegger > Assignee: Marcel Reutegger > Priority: Minor > > Currently the query handler either allows one modification or multiple > queries at a time. That is, write operations are separated from read > operations. With this synchronization scheme multiple queries may run > concurrently, but only in the absence of a write operation. > There is one major drawback with this synchronization: a single long running > query is able to block the whole workspace from committing changes. Because > the query handler is coupled to the Workspace via a synchronous event > listener, further processing is blocked until the query handler has finished > its event processing (reflecting the changes in the index). > Instead, each index modification should be non-blocking, in the sense that an > index modification should not have to wait for any queries to complete. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
