Subject [jira] Updated: (DIRSERVER-1161) search results are not streamed to the client until final done response is queued
Date Wed, 27 Aug 2008 18:07:44 GMT

     [ https://issues.apache.org/jira/browse/DIRSERVER-1161?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Karasulu updated DIRSERVER-1161:
-------------------------------------

    Fix Version/s:     (was: 1.5.4)
                   1.5.5

Moving to 1.5.5.  We need to move to MINA 2.0 where we have more leverage to fix this issue.
 I'm confident though that we'll have a solid solution to this problem for 1.5.5 since we've
already added the needed structures in ApacheDS to handle this properly.

> Search results accumulate in Events on the SessionBuffer.eventQueue within ExecutorFilter.fireEvent()
until final done response for the search is written to the session and then all results for
the search (possibly millions depending on the search and state of the directory) are written
out at once. This is a big problem for scalability and I gather from previous correspondence
with Alex that this behaviour is unexpected.
