--------------------------------------------
Summary: [replication] Storing of modified entries can be skipped
in full syncrepl mode
Key: DIRSERVER-1969
URL: https://issues.apache.org/jira/browse/DIRSERVER-1969
Project: Directory ApacheDS
Issue Type: Improvement
Affects Versions: 2.0.0-M16
Reporter: Emmanuel Lecharny
Fix For: 2.0.0-RC1
When we have replication setup, we do copy all the modified entries into a
btree for each replica we are dealing with.
We can avoid doing this as when a replica will reconnect, it will send the
latest EntryCSN it has received, and we can now locally find all the modified
entries by comparing the received entryCSN with the local entryCSNs using the
index, and send all the updated entries to the replica.
Although we can still keep a track of all the deleted entries (storing their DN
and entryCSN) so that w can send the deleted entries to the replica, instead of
asking the replica for all its DN and compute the deleted entries with that
set. We have to be careful though : the deleted entry should be sent in the
right order, within the modified entries.
