Henrik Hofmeister commented on COUCHDB-1367:
--------------------------------------------

@Robert - C-L aside - its still strange that its just some 'random' number of 
actions taken which is not really usable to the end user. That C-L could use a 
different implementation is besides the point imo - Its still is usable to get 
the current latest update seq - for whatever reason - if even to just show a 
progress bar in a to-be-developed feature in some gui application or whatever.

We use it internally to track progress of an aggragation application.

@Randall: in terms of adding a field or whatever - my only input is - less is 
more - update_seq makes perfect sense naming wise, it should just be the 
expected value. If you'll need to track other changes than doc changes later on 
in terms of replication or whatever - my uneducated guess is you're gonna need 
to do alot more than just have a number increase in any case. But thats just me

>          Components: HTTP Interface
>    Affects Versions: 1.1.1
>         Environment: Any

> Certain operations, (currently _revs_limit and _security changes) cause the 
> database header's update_seq to increase when the by_seq index (and therefore 
> _changes) has not changed, which is confusing in light of the naming 
> consistency.
