Subject [jira] [Created] (DIRSERVER-1969) [replication] Storing of modified entries can be skipped in full syncrepl mode

Emmanuel Lecharny created DIRSERVER-1969:

             Summary: [replication] Storing of modified entries can be skipped in full syncrepl
                 Key: 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

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.
