Recommended backend for Replication Config examples?

Dear All,

For the backend type for all the replication examples I'm
doing just now,
should we use bdb or hdb?

I notice that in slapd.conf.default we are using bdb.

Thoughts?

Gavin.

I'm in no hurry to deprecate back-bdb, and back-hdb's
initial performance is 
heavily dependent on priming its IDL cache. It's a tossup -
back-bdb with no 
subtree renames but less cache sensitivity, or back-hdb with
full directory 
semantics and more cache sensitivity. I suspect we'll be
carrying both for a 
long time, because of this tradeoff.

Understood. I'll stick with back-bdb for the examples,
unless the backend
is required to be changed for a specific example.

Thanks.
