Was just thinking we could do a quite simple backend for use with the accesslog
overlay and delta-syncrepl. It would write into flat files and do typical
logfile rotation on its own. The backing store would have a minimum of two files
- one for the suffix entry, one for the current chunk of logs. There would be a
configurable number of logfiles, with the oldest simply being deleted when it's
time to purge.


Two things I'd consider helpful for long-time archiving/auditing:

1. filenames to allow of "merging" different log flat files into one big file
store on a different slapd instance.


Not sure what you mean by this. As sequential logs you could just cat them if
you want to combine files into one, what does the filename have to do with it?


Sorry for unclear wording.
I'd like to move archived files of all MMR replicas into another single
filesystem directory and let a special auditing slapd with back-llog search in
them without having to muck with file names.


Then you would have to merge them entry-by-entry to preserve chronological order.


If we just use datestamps for filenames YYYYMMDD it should be no problem for you
to cat them in proper order.


There could be conflicting timestamps from different MMR replicas. Maybe
appending the serverID could be a solution?


Just keep them all in their own separate filesystem directories.
