--------------------------------------------
Summary: [perf] Add a replace() method in the index interface
Key: DIRSERVER-1907
URL: https://issues.apache.org/jira/browse/DIRSERVER-1907
Project: Directory ApacheDS
Issue Type: Improvement
Affects Versions: 2.0.0-M15
Reporter: Emmanuel Lecharny
Fix For: 2.0.0
Currently, when we update the Rdn index, we update it many times (one time per
RDN in the entry's DN), and we store a new version of each RDN with an updated
count of children and descendant.
This is done by dropping and adding each RDN, as we don't have a replace
method. This is extermelly costly, and we can save a lot of CPU with such a
replace method (the RDN index update cost one third of the global cost of an
addition, we could save around half of this, so this would give us a 16% speed
improvement for updates.)
