[jira] [Created] (DIRSERVER-1773) We should not store replicatio cookies in config if we use a one file config

Emmanuel Lecharny created DIRSERVER-1773:
--------------------------------------------

             Summary: We should not store replicatio cookies in config if we use a one file config
                 Key: DIRSERVER-1773
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1773
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 2.0.0-M8
            Reporter: Emmanuel Lecharny
            Priority: Critical
             Fix For: 2.0.0-M9


Although it's convenient, storing the cookie in the config file is really a big hassle when the configuration is stored using the SingleFileLdifPartition : we will flush this big file on disk for every modification the server receives...

IMO, it's ok if the config is based on the LdifPartition, but otherwise, it's simply overkilling. 

Another solution would be to store the cookies on disk as separate files.

----------------------------------------------

Hmmm, memoryMappedFile might not be useful : if the entry we want to change grows, we need to update the file entirely...

----------------------------------------------

We may also improve the way we use the SingleFileLdifPartition, by using a MemoryMappedFile over it...
