Subject [jira] Created: (DIRSERVER-1366) Delete take forever when having a lot of entries
Date Thu, 14 May 2009 09:43:45 GMT
Delete take forever when having a lot of entries
------------------------------------------------

                 Key: DIRSERVER-1366
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1366
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 1.5.4
            Reporter: Emmanuel Lecharny
            Priority: Blocker
             Fix For: 1.5.5


When we have a base with, say, 10000 entries, deleting one of them takes forever. A short
analysis conducted by Stefan Seelmann shown that the problem lies in the way we handle indexes
(log for one entry) :

JdbmStore: lookup in 0ms
JdbmStore: drop alias indices in 0ms
JdbmStore: drop ndn index in 78ms
JdbmStore: drop updn index in 34ms
JdbmStore: drop onelevel indices in 426ms
JdbmStore: drop sublevel index in 525ms
JdbmStore: drop parent onelevel index in 0ms
JdbmStore: drop existence index in 3ms
JdbmStore: master delete in 0ms
JdbmStore: sync in 7ms
