Ok, finally merged everything into 0.10.x. The extra patches rnewson
referred to are
r807473: disable gen_server timeouts for internal replication processes
r807477: fix a process leak in local changes feed consumer
I merged these in, too. Best, Adam

The improvements are huge. There are other fixes since this thread
started that finally allowed my stress test to pass, I think they all
should go into 0.10.

Hi all, I committed a good bit of replication-related code today and
wanted to check with the list regarding the 0.10 branch. Here's
what I
changed ..
one flat-out bugfix,
r807308, r807354: more precise and accurate calculation of
replication
progress
one new feature that could be classified as a bugfix depending on
your
point-of-view,
r807342, r807345: follow 302 redirects during replication
and two significant performance improvements (thanks rnewson for
all the
stress testing):
r807320, r807360: checkpoint at most once per 5 seconds
r807208, r807459, r807461: minimize the number of full commit
operations
There's another new feature hiding in that last set of commits,
namely the
ability to do a restricted full commit
POST /db/_ensure_full_commit?seq=N
which guarantees that everything up to and including update_seq N
will be
synced to disk. This is a weaker guarantee than a vanilla
_ensure_full_commit, and as a result it can be much faster in
certain
situations (e.g. replication from a server experiencing a heavy
batch=ok
write load).
I'd like to merge all of these into the 0.10 branch if that abides
by our
release policies. Best,
Adam
