Randall Leeds commented on COUCHDB-892:
---------------------------------------
I second what Bob said ("I'm surprised..."). I shouldn't be surprised, because
I've seen this code a lot, but oh well.
But I also think a start_seq might turn out to be useful in other situations in
the future:
a) an administrator changes the hostname of a box and wants to re-start
replication without starting from the beginning again.
b) fast-forward replication from a source when you trust a third party from
which you replicated the source.
c) scp a .couch file to create a redundant copy and jump-start continuous
replication.

> Issue Type: New Feature
> Components: Replication
> Reporter: Marco Monteiro
> Assignee: Filipe Manana
> Priority: Minor
>
> I'm using filtered replication to maitain a database that has a subset of the
> documents of some other database.
> The problem I have is when I change the filter. If the filter allows for more
> documents to be replicated, those that
> were created before the last replication are not replicated. So, I have to
> remove the database and recreate it.
> I see two solutions that can be implemented to help in this situation. The
> first one is for the filtered replication
> to restart whenever the filter changes (maybe also adding an argument to
> replicate to tell that" we want this to happen).
> Another solution is to add an argument to replicate ("start_seq", as sugested
> by fdmanana on IRC) that would be the
> source database ""local_seq that we want the replication to start from. This
> an be set to 1 to restart from first change.
