Subject [jira] Commented: (COUCHDB-782) Restarting replication
Date Thu, 03 Jun 2010 17:37:00 GMT


Randall Leeds commented on COUCHDB-782:

As far as a canonical format for remote databases:
1) strip the protocol so http and https aren't different
2) strip any login info
3) strip trailing slashes
4) uri-decode the result (I say decode only because I'm relatively sure it's idempotent, but
I don't know if encoding is. In particular, is % safe in a uri?)

Care would have to be taken to check for and migrate old checkpoint histories.

> So we had to restart replication on a server and here's something I noticed.
> At first I restarted the replication via the following command from localhost:
> curl -X POST -d '{"source":"http://localhost:5984/foo", "target":"http://remote:5984/foo"}'
> In response, futon stats:
> W Processed source update #176841152
> That part is great.
> Last night I did not have immediate access to the shell so I restarted replication from
remote (through curl on my mobile):
> curl -X POST -d '{"source":"", "target":"http://remote:5984/foo"}'
> The response in futon this morning:
> W Processed source update #1066
> ... and it kept sitting there like it was stalled and only continued in smaller increments.
> I restarted CouchDB and restarted from localhost - instant jump to 176 million.
> I'm just wondering what might be different accept for that one is against the public
interface, vs. localhost. I'd assume that replication behaves the same regardless.
