Re: back-bdb IDL limitations

A transaction begins and commits on a cluster boundary as well. If something bad happens in the middle of slapadding, the database will remain intact up to the previous cluster commit. I don't see this as a limitation as long as the administrator is given the information on the point his/her slapadd progressed to and as long as the cluster size is not too large.

Instead of writing to the index database upon addition of every single ID, slapadd can be made to buffer multiple IDs to make an ID cluster and writes the cluster as a single unit.
Question: What happens if the process dies, or the hardware shuts down in the middle of one of
these group commit operations ?
